The 1% Rule Explained - Filter, Not a Buy Signal

Last updated: July 2026

The 1% rule is a blunt filter: monthly rent should be about 1% of purchase price (or your all-in cost). Pass means “worth a deeper look,” not “buy it.” Fail is common on the coasts — still run cash flow if strategy differs.

1% vs 2% vs rent-to-price

Same idea, different hurdle. Check the 1% rule calculator, the stricter 2% rule calculator, or the continuous rent-to-price ratio when you want a percent instead of a badge.

Always underwrite next

A pass with rotten expenses still loses. After the screen, run rental cash flow (and usually NOI / CoC) before you schedule the inspection.

What this guide is not

Not a national standard and not a buy signal. Gross rent ≠ collected rent.
