The 1% rule is the most popular screening tool in real estate investing. It also eliminates about 95% of properties in any market where you'd actually want to own real estate. Austin, Denver, Raleigh, Nashville, Tampa: none of them come close. The rule was coined when mortgage rates sat at 4% to 5% and a decent three-bedroom in the Midwest cost $120,000. The math underneath has shifted. The rule has not.
What is the 1% rule?
The formula is almost insultingly simple. If the monthly rent is at least 1% of the purchase price, the property passes. If it falls short, you move on, or you bring a different investment thesis.
A $200,000 property needs $2,000/mo in rent. A $350,000 property needs $3,500. You can do the math in your head while scrolling Zillow, which is the entire point. No expense assumptions, no vacancy modeling, no cap rate debate. Two numbers, one division, done.
The problem is that "simple" and "accurate" are not the same thing. And in a 7%+ rate environment, they have never been further apart.
A brief history of the 1% rule (and why it is breaking)
The rule emerged in the early 2000s from online real estate forums, BiggerPockets chief among them. At the time, it worked. Rates were 5% to 6%. Prices were lower. The expense-to-rent ratio was more predictable. A property that cleared 1% almost always cash flowed, because the debt service was manageable relative to the rent.
Then three things happened simultaneously. Home prices roughly doubled in most metros from 2012 to 2023. Rents climbed too, but only 40% to 60%. And interest rates went from 3% in 2021 to 7%+ by 2023. The gap between what the 1% rule implies and what the numbers actually produce has never been wider.
When the rule was born, passing 1% with a 5% mortgage meant you had a comfortable cash-flow margin. Today, passing 1% with a 7.5% mortgage might mean you break even, or worse. The rule does not adjust for rates. It does not adjust for anything. That is its feature and its fatal flaw.
How to calculate the 1% rule: a worked example
The calculator above loads with a $250,000 purchase price and $2,300/mo rent. Here is the math:
At 0.92%, this property fails the 1% rule. In Memphis or Indianapolis, you would probably pass and keep scrolling. In Raleigh or Charlotte, 0.92% might be the best ratio you see all week, and the property could still be a solid investment.
Context matters. Move the rent slider to $2,500 and the ratio jumps to 1.0%. Negotiate the price down to $225,000 and you are at 1.02%. Small moves make or break the rule, which is exactly why it is a screen and not a verdict.
The 0.8% reality
Here is what nobody on the real estate forums wants to say out loud: most cash-flowing deals in decent markets hit 0.7% to 0.9%. Not 1%. The deals that actually close, that experienced investors actually buy, that lenders actually fund. They live in that range.
A $300,000 duplex in a B-class neighborhood of Kansas City renting for $2,400 total is a 0.8% property. It might cash flow $200 to $300 a month after all expenses. It will never pass the 1% rule. It is still a perfectly reasonable investment.
Rigid adherence to 1% in today's market means you are either shopping exclusively in the cheapest zip codes in the country, or you are not buying anything at all. Both outcomes are worse than adjusting the threshold to match reality.
Where the 1% rule still works (and what that means)
The 1% rule is not dead everywhere. You can still find properties that clear it in parts of Cleveland, Memphis, Detroit, Birmingham, and certain pockets of the Midwest and Deep South. But those numbers come with asterisks.
| Market | Typical ratio | The catch |
|---|---|---|
| Cleveland (East Side) | 1.0% – 1.4% | Higher vacancy rates, older housing stock, more management intensity. Deferred maintenance is the norm, not the exception. |
| Memphis (South / Whitehaven) | 1.0% – 1.3% | Solid rental demand but tenant turnover runs higher. Property management is not optional; it is survival. |
| Detroit (certain neighborhoods) | 1.2% – 2.0%+ | The ratios look incredible. The insurance costs, tax lien risks, and condition issues behind those ratios are less incredible. |
| Birmingham (West / Ensley) | 1.0% – 1.3% | Affordable entry point but economic base is narrow. Rent growth is slow. You are buying cash flow, not appreciation. |
| Indianapolis (East Side) | 0.9% – 1.2% | One of the more balanced cash-flow markets. Still requires careful neighborhood selection, where a few blocks make a big difference. |
Notice the pattern. Markets where the 1% rule works tend to be markets with lower price floors, older homes, higher management demands, and slower appreciation. The high ratio is not free money; it is compensation for higher operational risk. If you are buying a 1.3% property in East Cleveland from 800 miles away without a property manager you trust, the ratio is not protecting you.
Where the 1% rule is fantasy
In most of the Sun Belt and every coastal market, the 1% rule is a relic. A $450,000 house in Austin renting for $2,200 is 0.49%. A $600,000 condo in San Diego renting for $2,800 is 0.47%. A $380,000 townhouse in Denver renting for $2,400 is 0.63%. None of these will ever see 1%.
These are not bad investments. Austin appreciated over 50% between 2019 and 2022. Denver has been one of the strongest equity-growth markets in the country for a decade. San Diego rents have climbed steadily while vacancy stays below 4%. The investors buying in these markets have a different thesis: equity growth, tax advantages, long-term rent escalation, and portfolio diversification. The 1% rule measures none of that.
Using 1% as a filter in these markets means you filter out the entire market. If your strategy includes appreciation, drop the rule entirely and underwrite with a proper cash flow calculator instead.
The 2% rule: even more outdated
The 2% rule doubles the bar: monthly rent should be at least 2% of the purchase price. A $200,000 property would need to rent for $4,000 a month. In 2010, this was ambitious but achievable in dozens of Midwest and Southern zip codes. In 2026, finding that combination in a livable neighborhood is close to impossible.
Prices outran rents. Median home values roughly doubled while rents climbed 40% to 60%. The handful of markets that still show 2% numbers (parts of Detroit, certain blocks in St. Louis, rural Mississippi) tend to be areas where the high ratio is telling you something about the risk, not the opportunity.
Some investors still use 2% as a stretch goal. Filtering exclusively for 2% properties will leave you with either war-zone addresses or listings that have something wrong the seller is not mentioning. Treat it as a historical curiosity.
1% vs 2% across price points
The rule gets exponentially harder to pass as the purchase price climbs. Here is a quick reference:
| Purchase price | 1% target rent | 2% target rent | Reality check |
|---|---|---|---|
| $100,000 | $1,000/mo | $2,000/mo | 1% achievable in many Midwest markets. 2% possible in select neighborhoods. |
| $200,000 | $2,000/mo | $4,000/mo | 1% still findable in Memphis, Cleveland, Indianapolis. 2% requires a unicorn. |
| $350,000 | $3,500/mo | $7,000/mo | 1% tough outside multi-family or heavy value-add. 2% does not exist. |
| $500,000 | $5,000/mo | $10,000/mo | 1% requires premium rents or multi-unit strategy. 2% is fantasy math. |
| $750,000 | $7,500/mo | $15,000/mo | Neither rule applies. You are playing a different game entirely. |
What the rule ignores (and why that matters more now)
The 1% rule uses exactly two numbers: price and rent. Everything else is invisible to it. That was an acceptable trade-off when rates were low and expense ratios were predictable. In 2025, it is a trap.
- Interest rates. This is the big one. A 1.05% ratio with a 4% mortgage is a comfortable cash-flow deal. The same 1.05% with a 7.5% mortgage might be cash-flow negative. The rule does not know the difference. You need to.
- Operating expenses. Taxes, insurance, maintenance, management. A property in Texas or New Jersey can pass 1% and still bleed cash because 30% to 40% of gross rent goes to expenses before you touch debt service. Insurance costs in Florida have doubled in some counties since 2020.
- Vacancy. The rule assumes the property is always rented. A duplex that passes 1% with both units occupied fails the moment one sits empty for three months. Markets with higher ratios, like Cleveland and Detroit, often have higher vacancy rates to match.
- Property condition. A $150,000 house renting for $1,600 clears 1% easily. But if it needs a $12,000 roof, a $6,000 furnace, and $8,000 in foundation work, your real cost basis is $176,000 and the ratio drops to 0.91%. Cheap properties with high ratios and deferred maintenance is the oldest trap in rental investing.
- Neighborhood trajectory. A declining area with cheap prices produces beautiful ratios. Falling rents, rising vacancy, tenant turnover, and insurance issues will destroy those economics over three to five years. The rule cannot see direction, only a snapshot.
How to actually use the 1% rule in 2025
The rule is still useful. It is just not useful the way most people use it. Here is how experienced investors adapt it:
- Adjust the threshold by market. In a cash-flow market like Memphis or Cleveland, hold the line at 1%. In a balanced market like Kansas City or Indianapolis, use 0.8% to 0.9% as your filter. In a growth market like Raleigh, Charlotte, or Phoenix, 0.7% may be acceptable if the appreciation thesis is solid. One threshold does not fit all markets.
- Include rehab in the price. Always. If you are buying a fixer for $150,000 and spending $40,000 on renovation, your cost basis is $190,000. The rent needs to hit $1,900, not $1,500. BRRRR investors who forget this step end up with deals that look great on acquisition and terrible at refinance.
- Use market rent, not asking rent. Sellers and listing agents inflate rents on pro formas. That $2,400/mo in the listing might be $2,100 in the real world. Check Zillow, Rentometer, and local property management companies. Underwrite to the conservative number and be pleasantly surprised.
- Treat it as step one, not the final step. The 1% rule is a 10-second filter. Properties that pass get 20 minutes of your time in a rental property analyzer where you model cash flow, DSCR, cap rate, and total return together. Nobody should buy or reject a property based on a single ratio.
Properties that pass 1% but still lose money
This is the scenario new investors do not see coming. A $120,000 property in East Cleveland renting for $1,400 clears 1.17%. Looks great on paper.
But property taxes are $4,200/year. Insurance is $1,800. The roof needs $8,000 in two years. You are managing from out of state at 10% of rent plus a half-month leasing fee on turnover. You budget 8% for vacancy because the neighborhood runs higher than average.
Run those numbers through an actual cash flow calculator and the annual cash flow after debt service is negative. The 1% rule said yes. The bank account says no. High ratios in low-cost markets often come with high expense ratios that the rule cannot see.
Properties that fail 1% but are still good buys
A $500,000 house in a strong Raleigh suburb renting for $2,800 is a 0.56% ratio. The 1% rule would reject it immediately. But the market has been appreciating 6% to 8% annually. Rents have climbed 4% to 5% a year. You are building $30,000 to $40,000 in equity annually while generating modest tax benefits from depreciation.
Value-add plays tell a similar story. You buy at $200,000, spend $40,000 on renovation, and raise rent from $1,400 to $2,100. The going-in ratio on total cost is 0.88%, which fails the rule. But you just created $60,000 in equity through forced appreciation, and the property now cash flows. The 1% rule cannot see equity creation. A cap rate calculator and an after-renovation value analysis will.
1% rule vs other metrics
The 1% rule is a rough filter. These metrics do the actual underwriting. Knowing the difference saves you from over-relying on a single number.
| Metric | What it answers | Where the 1% rule falls short |
|---|---|---|
| Cap rate | What does the property yield unlevered? | 1% rule ignores expenses. Cap rate includes them. |
| Cash-on-cash return | What is your cash actually earning? | 1% rule ignores financing. Cash-on-cash reflects your real return. |
| DSCR | Can the property pay its own mortgage? | 1% rule ignores rates and loan terms. DSCR accounts for them. |
| GRM | How many years of rent to pay the price? | GRM is the 1% rule's cousin: still no expenses, but easier to compare across markets. |
A property at 1.1% with a 7.5% mortgage and high property taxes can have a worse DSCR than a property at 0.85% with a 6% conventional loan in a low-tax state. The 1% rule would prefer the first property. The lender, and your bank account, would prefer the second. Use the right tool for the right question.
Frequently asked questions
What is the 1% rule in real estate?
The 1% rule says a rental property's monthly rent should be at least 1% of the purchase price. A $200,000 property should rent for $2,000 or more. It is a screening tool, not an underwriting method. If a listing clears 1%, it deserves a closer look. If it does not, you either need an appreciation thesis or a way to force rents higher through renovation. The rule was more useful when it was coined, back when mortgage rates were 4% to 5% and expense ratios were more predictable. In a 7%+ rate environment, a property that barely passes 1% can still lose money every month.
Is the 2% rule realistic in 2026?
Almost never. The 2% rule made sense when you could buy decent houses for $80,000 and rent them for $1,600. Today, prices have outrun rents so dramatically that hitting 2% requires either a war-zone zip code, a multi-unit with above-market rents, or a property hiding $40,000 in deferred maintenance behind fresh paint. Parts of Detroit, South Side Chicago, and rural Mississippi will show you 2% numbers. They will also show you why the ratio is that high. Treat 2% as a curiosity, not a filter.
Does the 1% rule account for expenses?
No, and this is its biggest blind spot. The rule ignores property taxes, insurance, maintenance, vacancy, and management fees, the very costs that actually determine whether a property cash flows. A $150,000 house renting for $1,600 clears 1% easily. But in a high-tax state like Texas or New Jersey, 35% to 40% of gross rent goes to operating expenses before you touch the mortgage. Passing 1% gets you in the door. It does not tell you what is behind it.
Can a property that fails the 1% rule still be a good investment?
Some of the best-performing real estate in America fails the 1% rule. A $500,000 house in Raleigh renting for $2,800 sits at 0.56%, and investors buy there all day because the market has been appreciating 6% to 8% annually. The 1% rule was built for cash-flow investing. If your thesis is equity growth, tax advantages, and long-term rent increases, the rule is measuring the wrong thing entirely. Most of Austin, Denver, and the entire state of California live below 0.7%. Nobody is arguing those markets are uninvestable.
How do I use the 1% rule when screening listings?
Pull up 40 listings. Divide the asking rent by the list price on each one. Toss anything below your threshold (0.8% in a growth market, 1.0% in a cash-flow market) into the skip pile. The remaining 8 to 10 listings get a proper analysis with a cash flow calculator or rental property analyzer. The entire process should take about five minutes. That is the rule's only job: turning 40 listings into 10 worth your time.
Does the 1% rule work for multi-family properties?
Yes, and multi-family properties are more likely to pass it. A $400,000 fourplex renting for $4,400 total ($1,100 per door) clears 1.1%. The rule uses total rent versus total price regardless of unit count. But multi-family comes with higher expense ratios: more turnover, more maintenance, more management complexity. A fourplex passing 1% does not carry the same margin as a single-family at 1%. Run the actual cash flow numbers before you celebrate the ratio.
Should I include rehab costs in the purchase price?
Always. If you buy a property for $150,000 and spend $40,000 on rehab, your cost basis is $190,000. The rent needs to hit $1,900 to meet 1%, not $1,500. Ignoring rehab costs is the most common way investors manufacture false positives with this rule. BRRRR investors are especially prone to this. The acquisition price looks great, but the all-in number tells a different story.
What is a good rent-to-price ratio if 1% is the floor?
In dedicated cash-flow markets like Cleveland, Memphis, or Birmingham, 1.0% to 1.3% is solid. Above 1.3% is strong but warrants investigation, because high ratios often come with high vacancy, rough tenant pools, or deferred maintenance the seller is not disclosing. Above 1.5% in a decent neighborhood, verify the rent comps twice and get an inspection before you get excited. Below 0.7%, you are in appreciation territory and the 1% rule is the wrong tool for the job.
