## Start with evidence and a clear purchase strategy

Rental property deal analysis is a repeatable process: verify the property and income, budget operating costs, model financing, then test downside cases. Use the same definitions throughout. A ratio or AI recommendation cannot compensate for missing insurance, unrealistic rent or unpriced repairs.

## Step 1: build the property file

-   Record the price, legal unit count, condition and listing/source date.
-   Check leases or comparable rentals and distinguish asking from achieved rent.
-   Get tax information, insurance quotes and HOA/utility obligations.
-   Obtain loan terms and written repair estimates.
-   Confirm permitted use and relevant rental requirements with qualified local guidance.

## Step 2: calculate effective income and NOI

Hypothetical rental: price $300,000; monthly rent $2,500; annual scheduled rent $30,000. Subtract 5% vacancy ($1,500) for effective income of $28,500. Budget $4,000 taxes, $1,500 insurance, $2,280 management, $2,000 routine maintenance and $1,000 other operating costs. Total operating expenses are $10,780; NOI is $17,720. Cap rate is 5.91%. These are illustrative figures, not local market averages.

Vacancy of one month per two years is 1 ÷ 24 = 4.17%, not 5–8%. Choose your own evidence-based allowance and document it. Show replacement reserves separately under the convention used here; the [NOI guide](/blog/how-to-calculate-noi-real-estate) explains why definitions matter.

## Step 3: add debt and cash invested

Assume $18,000 quoted annual principal-and-interest debt service, $75,000 down payment, $8,000 acquisition costs and $12,000 immediate repairs. Total cash invested is $95,000. Cash flow before separate reserves is $17,720 − $18,000 = −$280; cash-on-cash return is approximately −0.29%. A separate $2,000 annual reserve makes budgeted cash flow −$2,280. The positive cap rate does not mean this financed deal cash-flows.

## Step 4: check coverage and downside cases

NOI-based DSCR is $17,720 ÷ $18,000 = 0.98. A lender using rent/PITIA may calculate a different ratio; match the definition in the [DSCR loan guide](/blog/dscr-loan-guide-how-to-calculate-dscr).

Scenario

Change from base

NOI before reserves

Base

Original inputs

$17,720

Lower rent

Scheduled rent down 10%; vacancy remains 5%; management remains 8% of effective income

$15,098

Higher insurance

Annual insurance increases $1,000

$16,720

Extra repair

One-time $8,000 capital repair

NOI unchanged; cash needed rises $8,000

The rent sensitivity adjusts management with collected income. The repair case shows why capital costs must be tracked even when they do not change NOI. Passing one downside case does not protect against every risk.

## Step 5: decide what must change

-   Reconsider the price, financing or scope if the verified deal misses your requirements.
-   Ask which inputs remain uncertain and what evidence could resolve them.
-   Maintain enough cash for vacancy and repairs.
-   Do not depend on appreciation or an unapproved refinance to rescue weak current cash flow.

Run the [rental property cash flow calculator](/tools/rental-property-calculator), [cap rate calculator](/tools/cap-rate-calculator) and [DSCR calculator](/tools/dscr-calculator). For a refinance strategy, follow the [BRRRR worked example](/blog/brrrr-method-guide-real-estate). Save the inputs and the reason for the decision so you can revisit it when a quote changes.

## Frequently Asked Questions

**Q: How do I analyze a rental property deal?**

A: Verify price, rent, condition and operating costs; calculate NOI; add debt and cash invested; then test vacancy, repairs and cost increases before deciding.

**Q: Does positive cap rate mean positive cash flow?**

A: No. Debt service, reserves and capital spending can consume more than the property’s NOI.

**Q: Is the 1% rule enough to decide whether to buy?**

A: No. It is a rough rent-to-price screen that ignores expenses, financing, condition and legal use.
