This is the data checklist for screening a buy and holdBuy & HoldAcquiring a rental property and holding it long-term for cash flow, appreciation, and equity paydown.Read more in the glossary rental before you commit to a deep dive. It covers the handful of numbers that decide whether a long-term rental is worth your time: the demand signals from census dataCensus DataGovernment-collected data on population, income, vacancy rates, owner/renter ratios, and demographics at the ZIP code or tract level.Read more in the glossary, the income and expense inputs, and the three return metrics lenders and investors actually use — cap rateCap Rate (Capitalization Rate)Net Operating Income (NOI) divided by the property's current market value or purchase price, expressed as a percentage.Read more in the glossary, DSCRDebt Service Coverage Ratio (DSCR)NOI divided by annual debt payments (principal + interest).

Work the list top to bottom. If a deal fails the demand checks, you do not need to run the return math. If it passes demand but fails the returns at honest assumptions, you do not need a deep dive.
Who this is for
This is for investors who have read the Buy and Hold guideLearn more in this articleBuy and Hold Real Estate: Pros, Cons, and When It Makes Sense and want a repeatable screening sequence for individual properties. It assumes you understand the strategy and now need a fast, disciplined way to evaluate specific deals.
It does not re-teach each metric in depth — every term links to its glossary definition. For the strategy itself, start with the guideLearn more in this articleBuy and Hold Real Estate: Pros, Cons, and When It Makes Sense.
Step 1: Market demand checks (census data)
Before any property-level math, confirm the market can sustain a long-term tenant. These come from free census dataLearn more in this articleHow to Use Census Data Before Buying a Rental Property.

Step 2: Income inputs
Build effective rental income from evidence, not the listing sheet.
Step 3: Expense inputs
Understating expenses is the fastest way to make a bad deal look good. Use full, honest lines.
Step 4: The three return metrics
Now run the numbers. Each links to a free calculator.
Cap rate — yield independent of financing
Cap rateCap Rate (Capitalization Rate)Net Operating Income (NOI) divided by the property's current market value or purchase price, expressed as a percentage.Read more in the glossary is NOINet Operating Income (NOI)Gross rental income minus operating expenses (taxes, insurance, maintenance, management, vacancies). Does NOT include mortgage payments.Read more in the glossary ÷ purchase price. Use it to compare the property against local alternatives. Run it in the cap rate calculator.
DSCR — can the property carry its own loan
DSCRDebt Service Coverage Ratio (DSCR)NOI divided by annual debt payments (principal + interest). Lenders typically require 1.25+.Read more in the glossary is NOINet Operating Income (NOI)Gross rental income minus operating expenses (taxes, insurance, maintenance, management, vacancies). Does NOT include mortgage payments.Read more in the glossary ÷ annual debt service. Below 1.0, the property cannot cover its mortgage from rent. Most lenders want 1.20+. Test it in the DSCR calculator.
Cash flow — what lands in your pocket
Cash flowCash FlowMonthly rental income minus ALL expenses—including mortgage principal and interest, taxes, insurance, maintenance, vacancy allowance, and property management.Read more in the glossary is income minus all expenses and debt service. Confirm it stays positive after a conservative stress test. Run it in the cash flow calculator.
Step 5: The stress test
A deal that only works at perfect assumptions is not a deal. Re-run the metrics with:
Rent $100/month lower than your base case
VacancyVacancy RateThe percentage of time or units that are unoccupied. Often expressed as a monthly cost: vacancy rate × gross rent.Read more in the glossary two points higher than the market average
One major repair in year one drawn from reservesCapital Reserves (CapEx)Monthly savings set aside for large, infrequent expenses: roof, HVAC, plumbing, appliances. Often 5–10% of gross rent.Read more in the glossary

FAQ
What is the most important number on this checklist?
There is no single one, but the market demand checks come first because they can disqualify a property before any return math matters. After that, DSCRDebt Service Coverage Ratio (DSCR)NOI divided by annual debt payments (principal + interest). Lenders typically require 1.25+.Read more in the glossary and stress-tested cash flowCash FlowMonthly rental income minus ALL expenses—including mortgage principal and interest, taxes, insurance, maintenance, vacancy allowance, and property management.Read more in the glossary tell you whether the property can carry itself and survive a bad month.
How many comps do I need for rent?
At least three comparable active listings or recent leases — similar in bedroom count, square footage, condition, and location. One comp is an anecdote; three start to form a defensible market rentMarket RentThe rent a property would command if leased today at arm's length in the current market.Read more in the glossary.
What DSCR should a buy-and-hold rental have?
Most lenders require 1.20 or higher for investment property, meaning NOI exceeds debt service by at least 20%. Even with a non-DSCR loan, treat 1.20 as a cushion target — it tells you how much room the property has before income fails to cover the mortgage.
Should I screen with these metrics or do a full analysis?
Screen first. This checklist is meant to kill weak deals fast. A full analysis — inspection, title, detailed comps, financing — is worth doing only on the deals that survive the screen and the stress test.
