The 1% Rule in Real Estate: Does It Still Work in 2026?

The 1% rule is the oldest, fastest screening tool in rental investing: monthly rent should be at least 1% of the purchase price. No spreadsheet, no financing assumptions — just a quick gut check on whether a listing is even worth a closer look.
The 1% Rule Formula
1% Rule: Monthly Rent ÷ Purchase Price ≥ 1%
Equivalently: monthly rent should be at least 1% of the purchase price.
A $200,000 property needs to rent for at least $2,000/month to meet the rule. Some investors also track a looser 0.8% threshold ($1,600/month on the same property) as a "still worth a look" tier rather than an automatic pass.
Worked Example
Our example property from this series — $200,000 purchase price, $2,400/month rent — comes in at a 1.2% rent-to-price ratio, comfortably clearing the 1% threshold:
| Threshold | Required rent on $200,000 | This property |
|---|---|---|
| 1% rule | $2,000/month | $2,400/month — meets it |
| 0.8% rule | $1,600/month | $2,400/month — meets it |
But this same property has a 4.1% cash-on-cash return and a 1.15 DSCR
It comfortably passes the 1% rule — and still lands in "fair" to "marginal" territory once you run cap rate, cash-on-cash return, and DSCR with real financing terms. That gap is the whole story of why the 1% rule needs a second opinion in 2026.
Why the 1% Rule Is Less Reliable Than It Used To Be
The 1% rule doesn’t know your interest rate. It was a much more reliable proxy for cash flow when mortgage rates were 4% and a smaller share of NOI went to debt service. At today’s higher rates, a property can meet the 1% rule and still produce weak or negative cash flow after financing — exactly what happened in our worked example above.
- It ignores financing entirely — same blind spot as cap rate, but even cruder
- It ignores property taxes, insurance, and HOA dues, which vary enormously by market
- It treats a $2,000/month rent on a $200,000 property in Texas the same as a $2,000/month rent on a $200,000 property with $8,000/year in property taxes
Screen fast, then verify with real numbers
RealtyDealScout checks the 1% rule automatically, then runs full cap rate, cash-on-cash, and DSCR analysis on every property — so a quick screen never has to be your final answer.
So Should You Still Use It?
Yes — as a first-pass filter, not a purchase decision. The 1% rule is genuinely useful for quickly discarding listings that are obviously overpriced relative to rent, especially when you’re scanning dozens of listings and can’t run full underwriting on each one. The mistake is treating a "pass" on the 1% rule as confirmation that a deal is good. It isn’t — it just means the deal is worth the five minutes it takes to check cap rate, cash-on-cash return, and DSCR properly.
