The One Percent Rule and Other Screening Shortcuts
Written by Evoque Lending Team · Published July 11, 2026
Screening rules exist to protect your time, not to make decisions. Where the one percent rule and its cousins work, where they mislead, and what the second pass looks like.
Investors face a volume problem: hundreds of listings, limited evenings. Screening rules solve it by sorting properties into worth-a-look and not-worth-the-click in seconds. The most famous is the one percent rule, and like all famous shortcuts it gets misused as a buying criterion when it is only a sorting criterion. Here is what the common screens actually test, where each one lies to you, and what the real analysis looks like once a property survives the screen.
What the one percent rule says
The rule asks whether a property's monthly rent is at least about one percent of its purchase price. A home whose rent clears that bar has a fighting chance of covering its costs; one that falls far short probably cannot, no matter how nice the kitchen. That is the entire rule. It is a rent-to-price ratio test, useful precisely because you can run it in your head while scrolling listings, and it correlates loosely with the coverage tests that actually matter later.
Why it stuck, and where it breaks
The rule earned its fame in an era and in markets where it sorted well. It still does in much of the country. But it breaks in predictable places. It knows nothing about expenses: two properties with identical rent-to-price ratios perform completely differently when one sits in a heavy-tax, high-insurance state and the other does not. It knows nothing about property class: an older building in a rough pocket can pass the screen and still lose money through turnover and repairs, while a newer home in a strong school zone can miss the screen and outperform for a decade. And in expensive coastal markets, almost nothing passes, which does not mean nothing there is investable; it means the screen is answering a question those markets do not ask. Treat a pass as permission to spend twenty more minutes, never as permission to offer.
The other screens in the toolbox
A few cousins do adjacent jobs. The gross rent multiplier divides price by annual rent, the same ratio flipped, handy for comparing similar properties inside one market. The half-of-rent expense heuristic assumes operating costs will consume roughly half of gross rent over the long run, before any loan payment; it is a blunt instrument, but it inoculates new investors against pro formas that budget expenses at fantasy levels. Price-per-door comparisons keep small multifamily shopping honest across different unit counts. Each screen shares the same DNA: fast, crude, directionally useful, and blind to the specific property in front of you.
The second pass: from screen to real numbers
A property that survives screening earns actual analysis, and the sequence matters. Verify the rent with comparable listings and a property manager's opinion, not the flyer. Pull real figures for taxes and quoted insurance. Apply honest accruals for vacancy, maintenance, and management. Then run the coverage math a lender will run: rent against the full monthly obligation including taxes and insurance. The break-even rent calculator shows the rent the deal must clear, and the DSCR calculator tells you whether the income supports the financing. That last check matters because it is the one your lender performs: a DSCR loan qualifies on exactly that ratio, and the current program minimum is here: Typically 1.00.
Screens filter markets too
Run the one percent test across a whole zip code's listings and you learn something about the market itself: where typical properties land tells you whether the area prices for income or for appreciation. That is often more useful than any single listing's result, because it aims your search at markets whose economics match your strategy before you evaluate a single address. It also calibrates expectations honestly: a market where nothing passes the screen is not hiding a secret bargain on page nine of the listings, and a market where everything passes deserves a hard question about why sellers there are so agreeable.
