Transactional deals like flips are relatively clean to analyze. You have a beginning, a middle, and an end. Residual deals are messier. Money goes out and comes back in over long periods. There may be multiple types of financing. And you might not know when, or even if, you plan to sell.

This is why the authors devote multiple chapters to analyzing cash-flowing rental properties. It’s not complicated once you have a framework. But it does require being thorough.

The example used here is a real deal that J purchased in January 2021 near Fort Myers, Florida. All numbers are actual figures.

Step 1: What Are You Putting Into It?

Before you can evaluate a rental, you need to know your total cost to get the property generating cash flow.

Cost assumptions:

• Purchase price: $133,000
• Land value (25% of purchase): $33,250
• Building value (75% of purchase): $99,750
• Improvements/renovation: $15,000
• Closing costs: $4,655
• Reserves: $0
• Total cost: $152,655

Why split land vs. building? Because only the building can be depreciated for tax purposes. More on that shortly.

Financing assumptions:

The lender agreed to finance 75% of the total cost ($114,491), leaving a down payment of $38,164. Terms: 25-year amortization at 4.125% interest.

Monthly mortgage payment: $612.26 ($7,347/year)

So the actual cash out of pocket to close: $38,164.

Step 2: What Are You Getting Out of It?

Now look at the income side.

The property manager estimated rent at $1,575/month. Vacancy in the area runs about 6%. No other income sources.

Annual income:

• Gross potential rent: $18,900
• Rent loss (6%): ($1,134)
• Gross operating income: $17,766

Annual operating expenses:

• Property taxes: $1,700
• Insurance: $987
• Property management: $1,777
• Turnover: $800
• Repairs and maintenance: $600
• Utilities (when vacant): $200
• Pool maintenance: $900
• Total operating expenses: $6,964

Net operating income (NOI): $17,766 - $6,964 = $10,802

Now add debt service and capital expenses to get cash flow:

• Debt service: ($7,347)
• Capital expenses: ($1,320)
• Annual cash flow: $2,135

A Note on Capital Expenses

Capital expenses are the big-ticket items that need to be replaced over time: roof, HVAC, water heater, appliances, plumbing, electrical. A lot of investors ignore these until they get blindsided by a $10,000 roof bill.

The right way to estimate them is to take each item’s expected cost, divide by its service life, and budget that amount annually.

For this property:

• Roof ($8,000 / 25 years): $320/year
• HVAC ($5,000 / 20 years): $250/year
• Water heater ($1,000 / 10 years): $100/year
• Electrical ($5,000 / 40 years): $125/year
• Plumbing ($5,000 / 40 years): $125/year
• Appliances ($2,000 / 6 years): $333/year
• Siding ($2,000 / 30 years): $67/year
• Total capital expenses: $1,320/year ($110/month)

Quick Tip: The 50 Percent Rule

Before doing a full analysis, there’s a rough tool called the 50 Percent Rule. It says that on average, operating expenses plus vacancy will eat about 50% of gross rents. So if a property rents for $1,000/month, you should expect roughly $500 to cover expenses, leaving $500 to service debt and generate profit.

This is only useful for a quick first pass. Don’t make final decisions with it.

Step 3: Evaluate Against All Four Return Types

Most investors look at cash flow and stop there. The authors say that’s a mistake. To properly evaluate a rental property, you need to look at all four return types from the earlier chapters.

1. Cash Flow and Cash-on-Cash Return (COC)

You already have cash flow: $2,135/year.

But raw cash flow doesn’t tell you whether the return is competitive. That’s what cash-on-cash return (COC) does:

COC = Annual cash flow / Cash invested

COC = $2,135 / $38,164 = 5.6%

Is 5.6% good? On its own, the stock market has historically done better. But this isn’t the only return from this investment. Keep reading.

2. Amortization (Loan Paydown)

Part of every mortgage payment goes to paying down the principal balance. That money doesn’t hit your bank account monthly, but it does build equity you can capture later when you sell or refinance.

In Year 1 of this deal, the principal paydown is $2,675.

The book introduces equity-on-cash return (EOC) to measure this:

EOC = Annual principal paydown / Cash invested

EOC = $2,675 / $38,164 = 7.0%

The loan paydown is actually generating a higher return than the cash flow.

Add them together for a “total return”:

Total return = ($2,135 + $2,675) / $38,164 = 12.6%

Suddenly this deal looks a lot more competitive with the stock market.

3. Tax Benefits (Depreciation)

Residential investment properties can be depreciated over 27.5 years. Since the building value here is $99,750:

Annual depreciation = Building value / 27.5

Annual depreciation = $99,750 / 27.5 = $3,627/year

If this investor is in the 24% federal tax bracket:

Tax savings = Taxable income deduction x Marginal tax rate

Tax savings = $3,627 x 24% = $871/year

The authors note that depreciation isn’t truly free money because you’ll typically owe recapture taxes when you sell. They frame it as an interest-free loan from the government. Hold the property long enough, and the compounding effect of reinvesting those annual savings becomes meaningful. Over twenty years, the future value of the annual tax savings can exceed $38,000 from just this one property.

4. Appreciation

The authors split this into market and forced appreciation.

Market appreciation: They’re honest that they don’t factor this into deal analysis. Historically, most markets haven’t outpaced inflation meaningfully over long periods. The 2008 crisis reminds us that values can drop, too. If market appreciation happens, treat it as a bonus, not a requirement.

Forced appreciation: This one they do value, because it’s controllable. J paid $133,000 and put $15,000 into renovations. After renovations, the property should appraise around $175,000.

Total investment to create that value: $148,000. New estimated value: $175,000. Equity created: $27,000.

ROI on forced appreciation = (Ending equity - Starting equity) / Starting equity

ROI = ($65,164 - $38,164) / $38,164 = 70.7%

That’s a 70.7% ROI just from the renovation creating value above what was spent.

Putting It All Together

A novice investor might look at 5.6% COC and walk away. An investor who looks at all four returns sees a deal generating 12.6% combined, plus significant tax benefits, plus a 70.7% return on forced appreciation.

The authors’ conclusion: there’s no such thing as a universally good or bad deal. The question is whether a specific deal meets your personal financial goals. If you figured out from the compounding machine chapter that you need 12% annualized returns, this deal clears that bar.
