Module 4: Analyzing Investment Properties
A Beginner's Guide to Building Wealth Through Property
Module Overview
Time Required: 120-150 minutes
Difficulty Level: Beginner to Intermediate
Prerequisites: Modules 1-3 completed
Learning Objectives
By the end of this module, you will be able to:
- Accurately estimate rental income for any property
- Calculate all operating expenses including hidden costs
- Understand and calculate key investment metrics (cash flow, cash-on-cash return, cap rate, ROI)
- Analyze properties using the 1% rule and other screening tools
- Project long-term returns including appreciation and equity buildup
- Complete a comprehensive property analysis from start to finish
- Identify good deals and recognize overpriced properties
- Make confident, data-driven investment decisions
Part 1: Understanding Investment Property Math
Real estate investing is fundamentally a numbers game. Emotions, hopes, and hunches lead to poor decisions. Data, analysis, and math lead to profitable investments.
This module teaches you how to "run the numbers" on any property so you can make intelligent decisions with confidence.
The Investment Analysis Framework
Every property analysis follows this structure:
Step 1: Determine Purchase Price What will you pay for the property?
Step 2: Estimate Rental Income What revenue will the property generate?
Step 3: Calculate Operating Expenses What will it cost to own and maintain the property?
Step 4: Calculate Cash Flow Income minus expenses = cash flow
Step 5: Calculate Investment Metrics How well does the investment perform?
Step 6: Project Long-Term Returns What happens over 5, 10, 20 years?
Step 7: Make Decision Buy, pass, or negotiate?
Let's work through each step systematically.
Part 2: Estimating Rental Income
Accurate rental income estimates are critical. Overestimate rent and you'll buy a money pit. Underestimate and you'll miss good deals.
How to Determine Market Rent
Method 1: Online Rental Listings (Quick & Free)
Process:
- Go to Zillow, Apartments.com, Craigslist, Facebook Marketplace
- Search for rentals in target neighborhood
- Filter by property type, beds, baths similar to your property
- Note asking rents for 5-10 comparable properties
- Calculate average
Important Notes:
- Use asking rents (what landlords want), not listed prices (what properties sold for)
- Look for recently listed properties (last 30 days)
- Adjust for condition differences (updated vs. dated)
- Check if utilities are included
- Verify properties are truly comparable (size, location, features)
Example Analysis:
Target Property: 3-bed, 2-bath, 1,400 sq ft, good condition
Comparable Rentals Found:
1. 3/2, 1,350 sq ft, good condition: $1,650
2. 3/2, 1,500 sq ft, excellent condition: $1,800
3. 3/2, 1,400 sq ft, average condition: $1,550
4. 3/2, 1,300 sq ft, good condition: $1,600
5. 3/2, 1,450 sq ft, good condition: $1,700
Average: $1,660
Median: $1,650
Conservative Estimate: $1,600 (using slightly below average)
Method 2: Rentometer (Quick Online Tool)
Process:
- Go to Rentometer.com
- Enter property address
- Enter bedrooms, bathrooms
- Review estimated rent range
- Use as secondary validation
Pros:
- Fast and easy
- Shows percentile (helps gauge market position)
- Free basic version
Cons:
- Less accurate than manual research
- May include outdated data
- Doesn't account for condition/features
Method 3: Property Management Companies (Most Accurate)
Process:
- Contact local property management companies
- Describe your property
- Ask what they could rent it for
- Get 2-3 opinions
Pros:
- Most accurate (they rent properties daily)
- Understand local micro-markets
- May share vacancy rates and tenant demand
Cons:
- Takes more time
- May need to position as potential client
- Different companies may give varying estimates
Method 4: Local Real Estate Agents
Process:
- Contact agents who handle rentals
- Ask for rental comps (comparable properties)
- Get their professional opinion
Pros:
- Access to MLS rental data
- Professional market knowledge
- May provide written rental comps
Cons:
- Not all agents handle rentals
- May be less accurate than property managers
- Takes time to establish relationship
Adjusting for Property Differences
Once you have comparable rents, adjust for differences:
Positive Adjustments (Charge More Rent):
- Updated kitchen/bathrooms: +$50-150/month
- Hardwood/upgraded flooring: +$25-75/month
- In-unit washer/dryer: +$75-150/month
- Garage/covered parking: +$50-100/month
- Fenced yard: +$25-75/month
- Extra bedroom: +$100-200/month
- Central air conditioning: +$50-100/month
- Better location within neighborhood: +$50-100/month
Negative Adjustments (Charge Less Rent):
- Dated kitchen/bathrooms: -$50-100/month
- Poor condition: -$100-200/month
- No central air: -$50-75/month
- Busy street/bad location: -$50-100/month
- Shared laundry or none: -$50-100/month
- No parking: -$50-75/month
- Less bedroom: -$100-200/month
Example Adjustment:
Comparable Property Rent: $1,500
- Has updated kitchen (+$100 to comp)
- Your property kitchen is dated (-$100 to your rent)
- Comp has garage (+$75 to comp)
- Your property no garage (-$75 to your rent)
Adjusted Estimated Rent for Your Property: $1,500 - $175 = $1,325
Conservative vs. Aggressive Rent Estimates
Conservative Approach (Recommended for Beginners):
- Use lower end of rent range
- Assume property won't rent at top of market
- Factor in longer vacancy periods
- Better to be pleasantly surprised than disappointed
Aggressive Approach:
- Use median or higher rent estimates
- Assume you'll get top-of-market rent
- Factor in minimal vacancy
- Risk: Cash flow problems if assumptions wrong
Example:
Rent Range for Comparables: $1,400 - $1,800
Average: $1,600
Conservative Estimate: $1,500 (below average)
Aggressive Estimate: $1,700 (above average)
Difference in Annual Income: $2,400
Impact on Deal Quality: Significant!
Recommendation: Always use conservative estimates. If the deal works with conservative numbers, it's truly a good deal.
Rental Income Red Flags
Be cautious if:
- Seller claims much higher rent than market comps show
- "Pro forma" (projected) rents significantly exceed current rents
- Property has been vacant for extended period
- Comparable properties sit on market for months
- Seller offers inflated rent estimates without documentation
- Area shows declining rents
- Many "For Rent" signs in neighborhood
Verify Everything:
- Ask to see current lease if property is rented
- Request rent roll for multi-unit properties
- Never take seller's word without verification
- Trust but verify
Part 3: Calculating Operating Expenses
Many beginners dramatically underestimate expenses, destroying cash flow and making bad investments. Let's calculate every expense accurately.
The Complete Expense Categories
Fixed Expenses (Consistent Monthly):
- Property taxes
- Insurance
- HOA fees (if applicable)
- Mortgage payment (principal & interest)
Variable Expenses (Change Over Time): 5. Maintenance and repairs 6. Vacancy 7. Property management 8. Utilities (if landlord pays) 9. Lawn care/snow removal (if landlord pays) 10. Pest control 11. Capital expenditures (CapEx)
Let's break down each expense category:
1. Property Taxes
What It Is: Annual taxes paid to local government based on assessed property value.
How to Find:
- Check county assessor/treasurer website
- Look at current owner's tax bill
- Ask listing agent
- Review property listing details
Important Notes:
- Taxes may increase after sale (reassessment at new purchase price)
- Look at tax history to see trend
- Check for pending reassessments
- Understand local tax rates
Example:
Property Purchase Price: $200,000
Annual Property Tax: $2,400
Monthly Property Tax: $200
Calculation Check:
$2,400 ÷ 12 months = $200/month
Potential Increase After Purchase:
Current Owner's Tax (on $180,000 assessment): $2,160/year
Your Tax (on $200,000 purchase): $2,400/year
Difference: $240/year = $20/month increase
Factor this into your analysis!
2. Insurance
What It Is: Landlord/dwelling insurance covering the building (not tenant belongings).
Types of Coverage:
- Dwelling Coverage: The building itself
- Liability Coverage: Protects you from lawsuits
- Loss of Rents: Covers rent if property becomes uninhabitable
- Personal Property: Covers appliances you own
How to Estimate:
- Get actual quotes from insurance agents
- Typical cost: $500-1,500/year ($42-125/month) for single-family
- More for multi-family
- Varies by location (flood zones, hurricane areas cost more)
Factors Affecting Cost:
- Property value
- Age of home
- Location/natural disaster risk
- Claims history
- Deductible amount
- Coverage limits
Never Skimp on Insurance: Proper coverage protects your investment. Saving $200/year isn't worth risking a $200,000 asset.
Example:
Single-Family Home: $800/year = $67/month
Duplex: $1,200/year = $100/month
Fourplex: $2,000/year = $167/month
3. HOA Fees (If Applicable)
What It Is: Monthly fees for condos and some townhouses/planned communities.
What It Covers:
- Exterior maintenance
- Common area upkeep
- Amenities (pool, gym)
- Insurance on building exterior
- Trash/water sometimes
How to Find:
- Listed in property details
- Ask seller/agent
- Review HOA documents
Critical Analysis:
$350/month HOA fee = $4,200/year
This dramatically impacts cash flow!
Ask yourself:
- What does it cover?
- Is HOA financially healthy?
- Any special assessments coming?
- Are fees rising rapidly?
- Do fees provide value?
HOA Red Flags:
- Rapidly rising fees (10%+ annually)
- Low reserve funds
- Deferred maintenance visible
- Special assessments recently levied
- High percentage of delinquencies
4. Mortgage Payment (Principal & Interest)
What It Is: Monthly loan payment if financing the property.
How to Calculate: Use mortgage calculator or formula:
Example:
Loan Amount: $160,000
Interest Rate: 7%
Term: 30 years
Monthly P&I: $1,064
(Principal + Interest only, not including taxes and insurance)
Important Notes:
- This is NOT an operating expense for cash-on-cash return calculations
- It IS a cash expense affecting cash flow
- We'll separate this in our metric calculations
5. Maintenance and Repairs
What It Is: Ongoing costs to keep property functional and rentable.
Includes:
- Plumbing repairs
- Electrical fixes
- Appliance repairs
- HVAC servicing
- Painting
- Minor repairs
- Pest control
- Lawn maintenance (if landlord responsibility)
How to Estimate:
Method 1: Percentage of Rent
- Conservative: 10-15% of gross rent
- Moderate: 8-10% of gross rent
- Aggressive (new property): 5-8% of gross rent
Method 2: Per Square Foot
- $0.50-1.00 per square foot per year
- 1,500 sq ft home: $750-1,500/year = $63-125/month
Method 3: Fixed Dollar Amount
- Single-family: $100-200/month
- Multi-family: $75-150/month per unit
Example (Conservative):
Rent: $1,500/month
Maintenance (10%): $150/month
Annual: $1,800
Covers:
- Occasional plumbing issues
- Minor repairs
- HVAC servicing
- Appliance repairs
- Misc fixes
Reality Check: Some years you'll spend $0. Other years you'll spend $3,000. The average matters for analysis.
Property Age Considerations:
- New property (0-10 years): Lower maintenance (5-8% of rent)
- Mid-age (10-30 years): Standard maintenance (8-12% of rent)
- Older (30+ years): Higher maintenance (12-15% of rent)
6. Vacancy
What It Is: Lost rent when property is unoccupied between tenants or during repairs.
How to Calculate: Set aside percentage of annual rent to account for vacancy.
Typical Rates:
- Strong market: 5% (18 days per year)
- Average market: 8% (29 days per year)
- Weak market: 10-15% (36-55 days per year)
Calculation:
Annual Rent: $18,000
Vacancy Rate: 8%
Annual Vacancy Cost: $1,440
Monthly Vacancy Reserve: $120
This means accounting for ~29 days vacant per year
Don't Assume Zero Vacancy: Even in strong markets, tenants move. You'll have turnover. Between tenants, you'll have:
- Time to clean/repair
- Time to show property
- Time to screen tenants
- Possible market conditions delaying rental
Conservative Approach: Use 8-10% vacancy even in strong markets.
7. Property Management
What It Is: Fee paid to property management company if you hire one.
Typical Costs:
- Monthly Fee: 8-12% of monthly rent
- Leasing Fee: 50-100% of first month's rent (one-time when placing tenant)
- Markup on Maintenance: 10-20% on contractor work
Example:
Rent: $1,500/month
Management Fee (10%): $150/month
Annual Cost: $1,800
Plus Leasing Fee: $1,500 (when tenant placed)
If tenant stays 2 years: $1,500 ÷ 24 months = $63/month effective
Total Effective Management Cost: $213/month
Self-Management: If managing yourself, factor your time cost:
- Showing property: 2-4 hours
- Screening tenants: 1-2 hours
- Lease preparation: 1 hour
- Monthly rent collection and communication: 30 min/month
- Maintenance coordination: 1-3 hours/month
- Accounting and record keeping: 1 hour/month
Recommendation: Include management fees in analysis even if self-managing initially. This gives you:
- True picture of property performance
- Option to hire manager later
- Accurate comparison between properties
8. Utilities (If Landlord Pays)
What It Includes:
- Water/sewer
- Trash
- Gas
- Electric
- Internet
Who Pays: Varies by market and property type:
- Single-family: Usually tenant pays all utilities
- Multi-family: Landlord often pays water/trash, sometimes gas/electric for common areas
- Condos/Townhouses: HOA may cover some utilities
Estimation:
If landlord pays water/sewer/trash:
Typical: $75-150/month depending on area
If landlord pays all utilities:
Can be $200-400/month total
Significantly impacts cash flow!
Strategy: Pass as many utilities to tenant as possible. Every utility you pay reduces cash flow and creates variable expense risk.
9. CapEx (Capital Expenditures)
What It Is: Major repairs/replacements for big-ticket items that wear out over time.
Major Systems and Lifespans:
- Roof: 15-25 years (Replace: $5,000-15,000)
- HVAC: 12-18 years (Replace: $4,000-8,000)
- Water Heater: 8-12 years (Replace: $800-1,500)
- Appliances: 8-15 years (Replace each: $500-1,200)
- Flooring: 10-20 years (Replace: $2,000-8,000)
- Paint (Exterior): 7-15 years (Cost: $3,000-8,000)
- Windows: 20-30 years (Replace: $5,000-15,000)
How to Estimate CapEx:
Method 1: Percentage of Rent
- Set aside 5-10% of rent for future CapEx
- $1,500 rent × 8% = $120/month
Method 2: Per System Calculation
Example Property Analysis:
Roof (20-year life, $10,000 replacement):
Annual Reserve: $10,000 ÷ 20 = $500/year = $42/month
HVAC (15-year life, $6,000 replacement):
Annual Reserve: $6,000 ÷ 15 = $400/year = $33/month
Water Heater (10-year life, $1,200 replacement):
Annual Reserve: $1,200 ÷ 10 = $120/year = $10/month
Appliances (12-year life, $3,000 for all):
Annual Reserve: $3,000 ÷ 12 = $250/year = $21/month
Flooring (15-year life, $4,000):
Annual Reserve: $4,000 ÷ 15 = $267/year = $22/month
Total CapEx Reserve: $128/month
Important: CapEx is not spent monthly—it's reserved for when systems need replacement. Some years you'll spend $0, other years $10,000. We account for the average.
Newer vs. Older Properties:
- New property (all systems new): ~5% of rent
- Average property (systems 5-10 years old): ~8% of rent
- Older property (systems 10+ years old): ~10-12% of rent
The Complete Expense Example
Let's calculate total expenses for a sample property:
PROPERTY DETAILS:
Purchase Price: $200,000
Rent: $1,600/month
Property Type: Single-family, 1,400 sq ft, 15 years old
MONTHLY EXPENSES:
Fixed Expenses:
Property Tax: $200
Insurance: $83
HOA: $0
Subtotal Fixed: $283
Mortgage (Not Operating Expense):
Loan: $160,000 at 7%, 30 years
P&I Payment: $1,064
Variable Operating Expenses:
Maintenance (10% of rent): $160
Vacancy (8% of rent): $128
Property Management (10% of rent): $160
CapEx Reserve (8% of rent): $128
Utilities: $0 (tenant pays)
Subtotal Variable: $576
TOTAL OPERATING EXPENSES: $859/month
TOTAL CASH EXPENSES (with mortgage): $1,923/month
MONTHLY CASH FLOW:
Income: $1,600
Operating Expenses: $859
Mortgage: $1,064
Total Expenses: $1,923
NET MONTHLY CASH FLOW: $1,600 - $1,923 = -$323 (NEGATIVE!)
This property has NEGATIVE CASH FLOW!
Should you buy it? Let's learn the metrics to decide...
Part 4: Key Investment Metrics Explained
Now that you can calculate income and expenses, let's learn the metrics that tell you if a property is a good investment.
1. Cash Flow
Definition: The money remaining each month after all expenses (including mortgage) are paid.
Formula:
Cash Flow = Rental Income - All Expenses (Operating + Mortgage)
Example:
Monthly Rent: $1,800
Operating Expenses: $900
Mortgage: $1,100
Cash Flow: $1,800 - $900 - $1,100 = -$200/month
Annual Cash Flow: -$200 × 12 = -$2,400/year
What It Means:
- Positive: Money in your pocket each month
- Negative: You pay out of pocket each month
- Break-even: Income exactly covers expenses
Target for Beginners:
- Minimum: $100/month per property
- Good: $200-300/month per property
- Great: $400+/month per property
Important Notes:
- Negative cash flow isn't always bad (if appreciation is strong)
- Positive cash flow is critical for beginners (safety buffer)
- Cash flow improves over time (rents rise, mortgage stays fixed)
2. Cash-on-Cash Return (CoC)
Definition: The annual return on the actual cash you invested.
Formula:
Cash-on-Cash Return = (Annual Cash Flow ÷ Total Cash Invested) × 100
Total Cash Invested Includes:
- Down payment
- Closing costs
- Immediate repairs/improvements
- Reserves (sometimes included, sometimes not)
Example:
Annual Cash Flow: $3,600 ($300/month)
Total Cash Invested: $50,000
CoC Return = ($3,600 ÷ $50,000) × 100 = 7.2%
What It Means: Your invested capital is returning 7.2% annually in cash flow alone (not including appreciation, tax benefits, or equity buildup).
Target Returns:
- Minimum: 5-6% (comparable to stock market without work)
- Good: 8-10%
- Great: 12%+
- Exceptional: 15%+
Why CoC Matters:
- Compares investments with different prices/down payments
- Shows efficiency of your invested capital
- Helps decide between multiple properties
Comparison Example:
PROPERTY A:
Price: $150,000
Down Payment: $30,000
Cash Flow: $200/month = $2,400/year
CoC: $2,400 ÷ $30,000 = 8%
PROPERTY B:
Price: $200,000
Down Payment: $40,000
Cash Flow: $300/month = $3,600/year
CoC: $3,600 ÷ $40,000 = 9%
Property B is better use of capital despite higher price!
3. Cap Rate (Capitalization Rate)
Definition: The return on property as if purchased all cash (no financing).
Formula:
Cap Rate = (Net Operating Income ÷ Purchase Price) × 100
Where NOI = Gross Rent - Operating Expenses (excluding mortgage)
Example:
Purchase Price: $200,000
Annual Rent: $18,000
Annual Operating Expenses: $7,200
NOI = $18,000 - $7,200 = $10,800
Cap Rate = ($10,800 ÷ $200,000) × 100 = 5.4%
What It Means: If you bought the property all cash (no loan), you'd earn 5.4% annually on your investment.
Why Cap Rate Matters:
- Compares properties regardless of financing
- Shows property's inherent return
- Market indicator (low cap = expensive market, high cap = cheaper market)
Typical Cap Rates by Market:
- A-class properties/markets: 4-6%
- B-class properties/markets: 6-8%
- C-class properties/markets: 8-10%
- D-class properties/markets: 10%+
Important Notes:
- Cap rate ignores financing (all-cash perspective)
- Cash-on-cash return accounts for leverage
- Both metrics matter for complete picture
Cap Rate vs. Cash-on-Cash:
Property: $200,000 purchase, 20% down
Cap Rate: 6% (property's inherent return)
Cash-on-Cash: 10% (your leveraged return)
Leverage improves your return!
4. Gross Rent Multiplier (GRM)
Definition: How many years of gross rent equal the purchase price.
Formula:
GRM = Purchase Price ÷ Annual Gross Rent
Example:
Purchase Price: $180,000
Annual Rent: $21,600 ($1,800/month)
GRM = $180,000 ÷ $21,600 = 8.3
Translation: It takes 8.3 years of gross rent to equal purchase price
What It Means: Lower GRM = better deal (less expensive relative to rent) Higher GRM = expensive (more years to recoup purchase price)
Typical GRMs:
- Strong cash flow markets: 8-12
- Balanced markets: 12-15
- Appreciation-focused markets: 15-20+
Why GRM Matters:
- Quick screening tool
- Easy to calculate
- Compares properties quickly
Limitations:
- Ignores expenses completely
- Doesn't account for financing
- Less useful than cash-on-cash or cap rate
Best Use: Initial screening. If GRM is reasonable, do deeper analysis.
5. Return on Investment (ROI)
Definition: Total return including cash flow, appreciation, equity buildup, and tax benefits.
Formula (Simplified):
ROI = (Total Benefits ÷ Total Investment) × 100
Total Benefits = Cash Flow + Appreciation + Equity Buildup + Tax Savings
Example (Year 1):
Total Investment: $50,000
Year 1 Benefits:
Cash Flow: $3,000
Appreciation (3%): $6,000
Equity from Principal Paydown: $2,400
Tax Savings (depreciation): $2,000
Total Benefits: $13,400
ROI = ($13,400 ÷ $50,000) × 100 = 26.8%
What It Means: Your total return (all sources) is 26.8%, far exceeding cash flow alone.
This Is Why Real Estate Works: Multiple return sources compound to create exceptional returns even when cash flow is modest.
6. The 1% Rule (Quick Screening Tool)
Definition: Monthly rent should equal or exceed 1% of purchase price.
Formula:
Monthly Rent ÷ Purchase Price ≥ 0.01 (1%)
Examples:
PROPERTY A:
Purchase: $150,000
Rent: $1,600
Ratio: $1,600 ÷ $150,000 = 1.07% ✓ PASSES
PROPERTY B:
Purchase: $250,000
Rent: $2,000
Ratio: $2,000 ÷ $250,000 = 0.8% ✗ FAILS
PROPERTY C:
Purchase: $100,000
Rent: $1,200
Ratio: $1,200 ÷ $100,000 = 1.2% ✓ PASSES (strong!)
What It Means:
- Passes 1% rule = likely positive cash flow
- Fails 1% rule = probably negative cash flow
- Higher than 1% = better cash flow potential
Important Notes:
- The 1% rule is a SCREENING tool, not a final analysis
- High-appreciation markets rarely meet 1% rule
- Passing 1% rule doesn't guarantee good investment
- Must do full analysis regardless
Regional Variations:
- Cash flow markets: Often meet or exceed 1% rule
- Appreciation markets: Often 0.5-0.7% (below 1%)
- Balance markets: Often 0.8-1%
Modified Rules:
- 2% Rule: Rare but indicates exceptional cash flow
- 0.7% Rule: Some investors accept in strong appreciation markets
7. Debt Service Coverage Ratio (DSCR)
Definition: How many times NOI covers debt service (mortgage payment).
Formula:
DSCR = Net Operating Income ÷ Annual Debt Service
Debt Service = Annual mortgage payments (P&I only)
Example:
Annual Rent: $19,200
Operating Expenses: $7,200
NOI: $12,000
Annual Mortgage Payments: $12,768
DSCR = $12,000 ÷ $12,768 = 0.94
What It Means:
- DSCR > 1.0: Income covers mortgage (positive cash flow)
- DSCR = 1.0: Income exactly covers mortgage (break-even)
- DSCR < 1.0: Income doesn't cover mortgage (negative cash flow)
Targets:
- Minimum: 1.0 (break-even)
- Good: 1.2-1.25 (20-25% cushion)
- Great: 1.4+ (40% cushion)
Why It Matters:
- DSCR loans require this ratio for approval (usually 1.0-1.25)
- Shows financial safety margin
- Indicates resilience to expense increases
8. Net Operating Income (NOI)
Definition: Income remaining after operating expenses but before mortgage payments.
Formula:
NOI = Gross Rental Income - Operating Expenses
Operating Expenses = Everything EXCEPT mortgage payment
Example:
Gross Annual Rent: $21,600
Property Tax: $2,400
Insurance: $1,000
Maintenance: $1,920
Vacancy: $1,728
Management: $1,920
CapEx: $1,728
Total Operating Expenses: $10,696
NOI = $21,600 - $10,696 = $10,904
Why NOI Matters:
- Used to calculate cap rate
- Used to calculate DSCR
- Shows property performance independent of financing
- Commercial properties valued on NOI
Metrics Summary Table
| Metric | Formula | What It Shows | Target |
|---|---|---|---|
| Cash Flow | Rent - All Expenses | Monthly profit/loss | $200+ positive |
| Cash-on-Cash | Annual CF ÷ Invested $ | Return on your capital | 8-10%+ |
| Cap Rate | NOI ÷ Price | Property's yield | 6-10% |
| GRM | Price ÷ Annual Rent | Price/rent relationship | 8-15 |
| 1% Rule | Rent ÷ Price | Quick screening | ≥1% |
| DSCR | NOI ÷ Debt Service | Cash flow safety | ≥1.25 |
| NOI | Rent - Opex | Operating profit | Higher better |

Research:
Comparable Rentals (3/2, similar size):
1. $1,750 (excellent condition)
2. $1,600 (good condition)
3. $1,550 (average condition)
4. $1,650 (good condition)
5. $1,625 (good condition)
Average: $1,635
Our Property Condition: Good, but needs minor updates
Conservative Estimate: $1,600/month
Annual Rent: $19,200
Step 2: Calculate Operating Expenses
MONTHLY OPERATING EXPENSES:
Property Tax: $225 (verified with county)
Insurance: $100 (quote obtained)
HOA: $0
Maintenance (10% of rent): $160
Vacancy (8% of rent): $128
Property Management (10% of rent): $160
CapEx (8% of rent): $128
Utilities: $0 (tenant responsibility)
Total Operating Expenses: $901/month
Annual Operating Expenses: $10,812
Step 3: Calculate Cash Flow
MONTHLY CASH FLOW:
Rental Income: $1,600
Operating Expenses: -$901
Mortgage Payment (P&I): -$1,197
Monthly Cash Flow: $1,600 - $901 - $1,197 = -$498
Annual Cash Flow: -$5,976
RESULT: NEGATIVE CASH FLOW!
Initial analysis shows negative cash flow. Should we immediately reject this property? Let's look at all metrics.
Step 4: Calculate Investment Metrics
Net Operating Income (NOI):
Annual Rent: $19,200
Operating Expenses: $10,812
NOI: $8,388
Cap Rate:
Cap Rate = ($8,388 ÷ $225,000) × 100 = 3.7%
This is LOW. A-class property territory.
Cash-on-Cash Return:
Annual Cash Flow: -$5,976
Total Invested: $55,000
CoC = (-$5,976 ÷ $55,000) × 100 = -10.9%
NEGATIVE return on cash flow alone!
Gross Rent Multiplier:
GRM = $225,000 ÷ $19,200 = 11.7
This is moderate to high—property is relatively expensive compared to rent.
1% Rule:
$1,600 ÷ $225,000 = 0.71%
FAILS the 1% rule (below 1%)
DSCR:
NOI: $8,388
Annual Debt Service: $14,364
DSCR = $8,388 ÷ $14,364 = 0.58
Well below 1.0—income doesn't cover mortgage!
Step 5: Long-Term Analysis
Despite negative cash flow, let's look at total returns:
Year 1 Complete Return:
Cash Flow: -$5,976
Principal Paydown: $2,880 (builds equity)
Appreciation (3%): $6,750
Tax Savings (depreciation, approx): $2,500
Total Year 1 Benefit: $6,154
ROI = ($6,154 ÷ $55,000) × 100 = 11.2%
5-Year Projection:
Cash Flow: -$5,976/year × 5 = -$29,880
Principal Paydown: ~$15,500
Appreciation (3%/year): ~$36,000
Tax Savings: ~$12,500
Total 5-Year Benefit: $34,120
Average Annual Return: 12.4%
Step 6: Decision Making
The Numbers Tell Us:
- Cash Flow: Negative $498/month (RED FLAG for beginners)
- CoC: -10.9% (Poor cash return)
- Cap Rate: 3.7% (Low—typical of expensive market)
- Total ROI: 11.2% (Good when including all benefits)
This Property Is:
- Appreciation play, not cash flow
- Suitable for experienced investors with capital reserves
- NOT suitable for beginners needing cash flow
- Might work in strong appreciation market
VERDICT: PASS (for beginner focused on cash flow)
Why Pass:
- Negative cash flow requires feeding property monthly
- Risky if job loss or expenses increase
- No cushion for unexpected issues
- Better opportunities likely exist
Who Should Buy This:
- Investor with strong reserves
- High-income earner wanting appreciation
- Someone in this market long-term
- Investor comfortable with negative cash flow

Part 7: Advanced Analysis Considerations
Sensitivity Analysis (What If Scenarios)
Test your analysis against different scenarios:
Scenario 1: Rent Lower Than Expected
Expected Rent: $1,600
Actual Rent: $1,450 (10% lower)
Impact:
- Cash Flow decreases $150/month
- CoC return drops significantly
- May turn positive cash flow negative
Lesson: Conservative rent estimates protect you
Scenario 2: Expenses Higher Than Expected
Expected Maintenance: $150/month
Actual Maintenance: $250/month (major repair year)
Impact:
- Cash Flow decreases $100/month
- May eliminate positive cash flow
Lesson: Adequate reserves are critical
Scenario 3: Extended Vacancy
Expected Vacancy: 8% (29 days)
Actual Vacancy: 90 days (25% of year)
Impact:
- Lost rent: $4,500
- Property loses money that year
- Reserves depleted
Lesson: Strong cash flow provides cushion
Scenario 4: Interest Rate Change (if refinancing)
Current Rate: 7%
Refinance Rate: 6%
Impact:
- Monthly payment decreases ~$100
- Cash flow improves ~$100/month
- CoC return improves
Lesson: Lower rates improve returns
Break-Even Analysis
What price makes this property work?
If property doesn't cash flow at asking price, calculate maximum price you'd pay:
Target Cash Flow: $200/month minimum
Current Cash Flow: -$300/month
Needed Improvement: $500/month = $6,000/year
Sources of Improvement:
Option 1: Lower purchase price
- Need to reduce mortgage payment by $500/month
- Requires ~$75,000 lower loan
- Offer: $150,000 instead of $225,000
Option 2: Combination
- Lower price by $40,000 ($185,000)
- Reduces payment by ~$266/month
- Find property with $234/month higher rent
- Combination makes deal work
Appreciation Scenarios
How does appreciation affect returns?
Property: $200,000 purchase
Annual Cash Flow: $2,400
3% Appreciation:
Year 5 Value: $231,855 (gained $31,855)
Year 10 Value: $268,783 (gained $68,783)
5% Appreciation:
Year 5 Value: $255,256 (gained $55,256)
Year 10 Value: $325,779 (gained $125,779)
Even 2% difference in appreciation dramatically impacts wealth building!
Market Cycle Timing
When you buy matters:
Buying at Market Peak (2006):
- Purchase: $250,000
- Market drops 30% (2008-2010)
- Value: $175,000
- Underwater on mortgage
- Forced to hold or take loss
Buying at Market Bottom (2011):
- Purchase: $175,000
- Market recovers (2013-2020)
- Value: $300,000
- Built substantial equity
- Multiple exit options
Lesson: Understand your market cycle. Buying at peaks is risky; buying in recovery/early expansion is ideal.
Part 8: Key Takeaways from Module 4
Core Principles
-
Analysis is everything:
- Emotions lie; numbers tell truth
- Conservative estimates protect you
- Detailed analysis prevents costly mistakes
-
Income and expenses must be accurate:
- Research comparable rents thoroughly
- Account for ALL expenses (many beginners forget CapEx, vacancy)
- Get actual quotes, don't guess
-
Multiple metrics provide complete picture:
- Cash flow: Monthly profit/loss
- CoC: Return on invested capital
- Cap rate: Property's inherent yield
- All matter; don't rely on just one
-
Cash flow is king for beginners:
- Positive cash flow provides safety
- Negative cash flow is risky
- Appreciation is bonus, not strategy
-
Long-term returns include multiple sources:
- Cash flow
- Appreciation
- Equity buildup
- Tax benefits
- Combined returns often 15-25% annually
-
The 1% rule is a starting point:
- Quick screening tool
- Not a final decision maker
- Always do full analysis
-
Conservative analysis prevents problems:
- Underestimate rents slightly
- Overestimate expenses
- Account for vacancy
- Build in cushion
Common Analysis Mistakes to Avoid
Mistake 1: Optimistic Rent Estimates
- Using asking price instead of actual rent
- Assuming top-of-market rent
- Not accounting for condition differences
Mistake 2: Underestimating Expenses
- Forgetting CapEx reserve
- Ignoring vacancy
- Not accounting for all maintenance
Mistake 3: Failing to Account for All Cash Invested
- Only counting down payment
- Forgetting closing costs
- Ignoring immediate repairs needed
Mistake 4: Relying on Seller's Numbers
- Seller-provided rent may be inflated
- Pro forma numbers are projections, not reality
- Always verify independently
Mistake 5: Ignoring Market Comparisons
- Every metric should be compared to market averages
- 5% cap rate in 8% cap market means overpriced
- Understand your market's typical metrics
Mistake 6: Analysis Paralysis
- Don't overanalyze and miss opportunities
- Get comfortable making decisions with good (not perfect) information
- Move forward when numbers work
