Frequently asked questions

What exactly does the 1% rule check for?+

The 1% rule is a quick screening test stating that monthly rent should be at least 1% of the property's purchase price — for example, a $200,000 property should rent for at least $2,000 per month to pass. It's meant for rapid comparison, not a final investment decision.

Why do so few properties meet the 1% rule in expensive markets?+

The 1% rule tends to fail in high-appreciation coastal and urban markets where prices have risen faster than rents, while it's easier to meet in lower-cost, cash-flow-focused markets in the Midwest and South. It reflects a cash-flow-oriented strategy, not a universal standard for all markets.

If a property fails the 1% rule, does that mean it's a bad investment?+

Not necessarily — it may still be a strong investment if it's expected to appreciate significantly, which the 1% rule doesn't account for at all. The rule is a rough cash-flow filter, and appreciation-focused investors in strong markets routinely buy properties that fail it.

Does the 1% rule account for expenses like taxes, insurance, and maintenance?+

No — it's a gross, back-of-envelope calculation using rent and price only. A property that technically 'passes' can still have negative cash flow once real operating expenses and the mortgage payment are factored in, so it should be followed by a full cash flow analysis.

How does the 1% rule differ from the 2% rule?+

They use the same formula — monthly rent as a percentage of price — but the 2% rule sets a much higher bar, which is rarer to find and is generally associated with higher-risk, lower-appreciation markets or properties needing significant work. Neither threshold is inherently 'correct'; they're just different risk/return screening levels.
