The 1% Rule in Real Estate: Does It Still Work in 2025?
Where the 1% rule came from, which cities still pass it, and what to use instead when the math doesn't add up.
The 1% rule is the most popular screening tool in rental property investing. It's fast, it's simple, and for decades it helped investors quickly separate deals worth analyzing from deals to skip. But home prices have outpaced rent growth in most of America, and investors are asking a reasonable question: is the 1% rule still relevant?
The short answer is yes — as a filter, not a standard. Here's the full picture.
What Is the 1% Rule?
A property listed at $200,000 should rent for at least $2,000/month to pass the 1% rule. A $350,000 property needs $3,500/month. It's a ratio test — and it approximates whether a property can generate positive cash flow after expenses and financing.
The logic works because if you're collecting 1% of the purchase price every month (12% of the price per year in gross rent), you generally have enough margin to cover property taxes, insurance, maintenance, vacancy, and a mortgage payment while still having cash left over.
Below 1%, the margins get thin. The further below 1% you go, the more likely you are to break even or lose money on a monthly basis — especially with today's interest rates.
Where It Came From
The 1% rule emerged from investor forums and real estate investing communities in the early 2000s. There was also a 2% rule (much more aggressive — monthly rent should be 2% of price) that was achievable in some Midwest and Southern markets before the 2010s price run-up.
These rules were never academic or scientific. They're practitioner rules of thumb — shortcuts developed by investors analyzing hundreds of deals who noticed that below certain rent-to-price ratios, deals rarely cash flowed. The 1% threshold proved to be a reliable dividing line across most markets and financing scenarios.
The Problem: Most Markets Fail It Now
Here's the uncomfortable reality. We track rent-to-price ratios across 300 US cities, and the majority don't pass the 1% rule at median prices and rents.
Expensive metros fail badly. Seattle comes in around 0.32%. Denver around 0.38%. Even historically affordable cities like Raleigh and Nashville have been pushed well below 1% by the post-2020 price surge. When a $400,000 house rents for $1,800/month, you're at 0.45% — nowhere close.
The markets that still pass tend to share certain characteristics: lower home prices (typically under $200,000), strong rent demand relative to ownership demand, and often slower appreciation. Think Rust Belt cities, smaller Southern markets, and some Midwest metros.
Does Failing the 1% Rule Mean It's a Bad Deal?
No. And this is where investors go wrong by treating the 1% rule as a hard standard instead of a filter.
A property at 0.7% in a market growing 3% per year, with strong job creation and rising rents, might dramatically outperform a 1.1% property in a shrinking market over a 10-year hold. The 1% rule doesn't capture appreciation, rent growth, equity buildup, or tax benefits — and those factors often dominate total returns.
The 1% rule was designed for screening, not decision-making. It tells you "this deal is likely to cash flow" or "this deal needs more scrutiny." It doesn't tell you "this is a good investment" or "this is a bad investment."
What to Use Instead (or Alongside)
Cap rate: the real analysis
If the 1% rule is the quick filter, cap rate is the thorough analysis. Cap rate accounts for actual expenses — taxes, insurance, maintenance, vacancy — which the 1% rule ignores entirely. A property at 0.85% with very low taxes could have a better cap rate than a 1.05% property in a high-tax state.
Cash-on-cash return: the personal metric
Cash-on-cash return factors in your financing, which the 1% rule also ignores. With a low interest rate (say you assume a loan at 5%), a 0.8% property might still generate a healthy cash-on-cash return. With a 7.5% rate, even a 1% property might struggle.
The 0.8% adjusted rule
Some investors have simply adjusted the threshold downward. In a world where 6–7% interest rates are the norm and home prices are elevated, 0.8% might be the new 1%. A $300,000 property renting for $2,400/month (0.8%) can still work with the right financing and reasonable expenses.
This isn't official — it's just a practical adjustment that reflects the current market. The principle is the same: set a minimum rent-to-price ratio below which you don't bother running full analysis.
Gross rent multiplier (GRM)
GRM is just the inverse of what the 1% rule measures. A property that passes the 1% rule has a GRM of 8.3x or lower (purchase price ÷ annual rent). A GRM under 10 is generally considered favorable for cash flow. GRM is more granular than a binary pass/fail — you can see exactly how close a deal is to working.
Three Strategies When Nothing Passes
1. Look at different markets
If your local market is at 0.5%, the 1% rule isn't broken — your market is just expensive relative to rents. Many investors successfully invest remotely in higher-yield markets. A Portland investor buying in Birmingham. A San Diego investor buying in Memphis. Out-of-state investing has its own challenges (property management becomes essential), but the math works.
2. Force the ratio with value-add deals
Buy below market, renovate, increase rents. A property that's at 0.7% at listing price might be at 1.1% after you negotiate a discount, rehab the kitchen and bath, and raise rent to market rate. This is essentially the BRRRR strategy — and it works precisely because it creates deals that pass the 1% rule in markets where turnkey properties don't.
3. Shift your strategy
If you're investing in a low rent-to-price market like Denver or Austin, stop trying to make it cash flow like Memphis. Accept that your returns will be appreciation-driven, keep the property cash-flow neutral or slightly positive, and let equity growth and mortgage paydown do the work over a longer hold period. Not every market is a cash flow market, and that's okay — as long as your expectations match your strategy.
The Bottom Line
The 1% rule still works as what it always was: a quick filter to identify deals worth deeper analysis. What's changed is that fewer deals pass it, which means you need to either look in different markets, create the ratio through value-add work, or adjust your expectations about what "good" looks like in your target market.
Don't throw out the 1% rule — just stop using it as your only tool. Pair it with cap rate, cash-on-cash return, and market fundamentals for the complete picture.
