The 1% rule is a fast reality check: a rental's monthly gross rent should be about one percent of its purchase price. It flags properties worth a closer look, but it ignores taxes, financing, and expenses, so it is a filter, not a full financial analysis.
The Rule in One Sentence
The 1 percent rule is a fast reality check: a rental's monthly gross rent should be about one percent of its purchase price. Under the rule, a property bought for $200,000 should rent for around $2,000 a month. It is a quick screen to flag whether a deal is worth a closer look, not a complete financial analysis.
Pass the test and the property earns deeper attention; fail it and the numbers may not work as a rental. It is the kind of shortcut that separates promising deals from likely duds in seconds.
What the Rule Captures
The rule captures the basic relationship between the price of the property and the rent it can produce. When the monthly rent is a meaningful share of the price, there is more room for the rent to cover the mortgage, taxes, insurance, and maintenance. When the rent is a tiny share of the price, the property is unlikely to cash flow.
It works best as a comparison tool across similar properties and markets. A rental meeting the 1 percent threshold is not automatically a good deal, but it is a deal worth examining further.
What the Rule Ignores
The 1 percent rule ignores taxes, financing, vacancy, and expenses, so it is a filter, not a full financial analysis. Two properties can both meet the rule and produce very different results because of their property taxes, interest rates, condition, and running costs. The rule cannot tell you which is the better investment.
In some markets, meeting the 1 percent rule is difficult because prices are high relative to rents, while in others it is the norm. Treat the rule as a starting screen and run the full underwriting on anything that passes.
Using the Rule With a Full Analysis
Use the 1 percent rule to screen, then follow up with a complete underwriting of the deal. Calculate the real cash flow with your actual financing, the taxes, the insurance, the vacancy allowance, and the maintenance reserve. Compare the cash-on-cash return and the total return with appreciation.
The rule gets you to the right questions; the full analysis answers them. A property that passes both the screen and the deep dive is a genuine candidate, and one that fails either deserves skepticism.
