How it works

The 1% rule says monthly rent should be at least 1% of the purchase price. It's a quick screen, not a verdict.

In many markets today, 0.7–0.9% is realistic. Always run the full numbers before offering.

What the 1% rule actually tells you

The 1% rule is a filter, not a formula for profit. If a $200,000 property rents for $2,000 a month, it passes — and historically, properties at that ratio have a good chance of cash-flowing after typical expenses and a mortgage. If it rents for $1,200 (0.6%), the math almost never works at today's interest rates, and you can move on in seconds.

Think of it as the first gate in a rental property analysis: fail the 1% rule badly and the deal needs an unusual angle — a big value-add, house hacking, or a steep discount — to be worth more of your time.

Is the 1% rule still realistic today?

In much of the country, no. Home prices have outpaced rents in most metros, so 0.6–0.9% is now the realistic range in many markets, and passing deals cluster in the Midwest and South. At higher interest rates, even a 1% property can cash-flow poorly once taxes and insurance are counted.

That's why the rule should start your analysis, not end it. A 0.85% property with low taxes and a cheap loan can outperform a 1.1% property in a high-tax county. The ratio gets you to the shortlist; the full analysis picks the winner.

The 1% rule vs the 2% rule and 50% rule

The 2% rule — rent at 2% of price — is the aggressive version, mostly achievable only in low-price, high-turnover markets where hidden costs often eat the extra yield. The 50% rule is a companion heuristic: expect about half of gross rent to go to operating expenses before the mortgage. A property that passes the 1% rule and roughly follows the 50% rule usually has room for a mortgage payment.

Use all three as a quick mental stack: ratio first, expense sanity check second, then a real cash-flow calculation with actual taxes, insurance, and loan terms.

Frequently asked questions

Is the 1% rule still realistic?

In high-cost markets it's rare. Treat it as a filter to decide which deals deserve a full analysis.

Does the 1% rule use purchase price or total cost?

Strictly it's purchase price, but if you're doing meaningful renovations, include them — use your all-in cost for a honest screen.

A property passes the 1% rule. Is it a good deal?

Maybe. Passing means it deserves a full analysis: cap rate, cash flow, and cash-on-cash with real expense numbers. Plenty of 1% properties still lose money after taxes, insurance, and repairs.
