The 1% Rule in 2026: Almost No Market Passes. Use This Instead

The 1% rule is the most widely cited shortcut in residential real estate investing. It is also, for the vast majority of US markets in 2026, a screen that nothing passes. Run the numbers across RentalCalcs county data covering 1,359 counties with both price and rent observations: only 4 counties clear a 1.0% monthly rent-to-price ratio. Forty-three clear 0.75%. The rule didn't just get harder to meet. It became functionally irrelevant as a national screen.

That doesn't mean you throw out ratio screens entirely. It means you need to understand what happened to the math, recalibrate the threshold, and layer in three additional metrics before you commit capital. Here's how to do that.

What the 1 percent rule says and where it came from

The rule says a rental property should generate monthly rent equal to at least 1% of its purchase price. A $200,000 house should rent for at least $2,000 per month to pass.

The rule measures gross rent against purchase price. It is closer to a simplified version of the Gross Rent Multiplier than a cap rate or cash-on-cash return. It does not account for expenses, vacancies, or financing terms, which is both its strength (simplicity) and its primary weakness (incompleteness).

Its origins trace to an era when mortgage interest rates were higher, often 8–12%, meaning properties needed to generate more rental income just to cover financing costs. The rule emerged from a period when prices were low enough, and the investor base scrappy enough, that $150,000 houses in secondary markets were common and $1,500 rents were achievable. The rule gained popularity because it simplifies the early stages of deal analysis. Instead of studying detailed financial models immediately, buyers could apply a quick mental calculation.

That was then. The price-to-rent relationship that made the rule useful no longer exists in most of the country.

The 2026 reality: rent-to-price ratios across US counties

According to RentalCalcs market data covering 1,359 counties with paired price and rent figures, only 4 counties in the United States currently clear a 1.0% monthly rent-to-price ratio, and just 43 counties clear 0.75%. The overwhelming majority of the country sits well below both thresholds.

To understand why, put the national medians side by side. The median US home sale price was $410,700 in Q2 2026, according to Census Bureau data. The national median single-family rent reached $2,100 in the first half of 2026, down 1.6% year over year.

Do the math: $2,100 divided by $410,700 is a rent-to-price ratio of 0.51%. That is roughly half of what the 1% rule requires. To hit 1.0% at a $410,700 purchase price, you would need $4,107 in monthly rent. The median rent is not even close.

The Q2 2026 national median sits $93,600 above the Q2 2020 median of $317,100, a 29.5% increase over six years. Since 2020, single-family rents have increased 32%, adding about $600 per month. Prices and rents both rose post-pandemic, but they did not rise in sync. In most metros, prices ran harder and faster. The ratio compressed. It has not recovered.

The counties that do pass a 1.0% screen are concentrated in a small set of lower-priced Midwest and mid-South markets where median purchase prices remain under $120,000. These are not markets you stumble into. They require deliberate targeting, and even at those prices, property condition, vacancy risk, and property taxes require scrutiny. Browse the cash flow market rankings to see where the ratio picture is least bad nationally.

Why the rule died: the price and rate math since 2020

Two forces killed the rule simultaneously: a 29% home price surge and a mortgage rate that went from generational low to uncomfortable high in about 18 months.

The average 30-year fixed rate bottomed in 2021 at just under 3%. The annual average jumped to 5.34% in 2022 and 6.81% in 2023 as inflation and Treasury yields rose. It averaged 6.72% in 2024 and 6.60% in 2025. As of August 6, 2026, the 30-year fixed rate averaged 6.69% per Freddie Mac's weekly survey.

That rate shift alone recalculates into a brutal monthly payment change. Consider a $350,000 purchase with 25% down, so a $262,500 loan. At 3.0%, principal and interest runs about $1,107 per month. At 6.69%, the same loan runs about $1,692 per month. That is $585 more per month in debt service, before taxes, insurance, maintenance, or vacancy. No investor's rent roll kept pace with that.

Meanwhile, rent growth has cooled. Single-family rent prices in February 2026 increased just 1.1% year over year, a pronounced slowdown from the 2.6% increase between February 2024 and 2025, and one-third of the pre-2020 average of 3.3%. Growing rental supply continued to pressure pricing, as elevated apartment deliveries, build-to-rent communities, and increased competition weighed on rents. Nearly half of the 1,099 markets analyzed recorded annual rent declines in the first half of 2026.

The 1% rule assumed a world where prices were affordable and rates were high. It became temporarily fashionable again in the low-rate 2014–2020 window when rates were benign and the rule felt achievable in secondary markets. Now rates are back to elevated levels and prices have not corrected. The squeeze is on both sides of the ratio. A property that passes the 1% rule is not automatically cash-flow positive in this environment. But a property that fails it by a wide margin is almost certainly cash-flow negative after accounting for financing costs and operating expenses.

What 0.7 percent buys you at 2026 rates: a worked example

Let's use a property that clears 0.7%, a threshold 43 counties meet at the county median, and model it with real 2026 financing.

Example property (illustrative round numbers):

Monthly income and expenses:

At 0.7%, with a 6.75% rate and standard expense ratios, this deal loses $255 per month. To break even, you need either a lower price, a higher rent, a larger down payment, or all three. Bump the down to 40% and the P&I drops to $700, and the property still loses about $79 per month before capital expenditures. That is not a business. That is parking money for appreciation.

Now run the same model at a rent-to-price ratio of 0.85% on the same $180,000 property: rent becomes $1,530. With the same expense assumptions and 25% down, the monthly loss narrows to about $31, essentially breakeven before capital expenditures. Still not positive, but far better than the 0.7% case. At 1.0%, rent is $1,800 and cash flow reaches about $193 per month at 25% down. That is an actual return.

The lesson: even 0.7% doesn't get you there at 6.75%. You need close to 0.9% just to break even before standard expenses plus current financing, and 1.0%+ to get a return worth the risk. The specific numbers in your market depend on local taxes, insurance, and vacancy. Use the single-family calculator to run your own market's inputs.

Better screens: rent-to-price ratio, cap rate, and dollar cash flow

The 1% rule's failure as a national screen doesn't mean screening is wrong. It means one-input screening is wrong. Use three numbers in sequence:

1. Rent-to-price ratio as the first gate

Rent-to-price ratio is monthly rent divided by purchase price, expressed as a percentage. It is a one-number screen for whether a property's yield is likely to generate cash flow before you dig into full underwriting. In 2026, a reasonable threshold is 0.85% at 6.75% financing with 25% down. That is the floor where full underwriting has a chance to show black ink. Below 0.75%, you are underwriting for appreciation, not income.

The ratio ignores property taxes (high in Texas, Illinois, New Jersey; low in Alabama, Tennessee, Hawaii), insurance costs (rising in Florida, Louisiana, coastal California), maintenance ratios (old housing stock in the Midwest carries higher maintenance), and vacancy. Two deals at the same ratio can produce radically different cash flow after expenses.

2. Cap rate as the second gate

Once you've cleared the rent-to-price screen, calculate cap rate: net operating income divided by purchase price, before financing. As of early 2026, stabilized multifamily assets nationally trade in the 5.0–5.7% range, with value-add assets priced higher. For single-family rentals in secondary markets, a 6.5–8.0% unlevered cap rate is the range where the deal earns a closer look. Below 5.5%, the acquisition is an appreciation play regardless of what the rent-to-price ratio says.

3. Dollar cash flow after debt service

This is the number that pays your bills. A $40 monthly surplus is not a cash-flowing rental. Target a minimum of $150–$200 per month per door after all expenses and debt service before calling a deal cash-flow positive. Below that, a single HVAC replacement or one month of vacancy wipes out a year of positive returns.

Rent-to-price is the fastest screen for "does this even merit full underwriting?" Cap rate tells you what the asset earns unlevered. Dollar cash flow tells you whether the financing structure actually works.

Where the rankings say cash flow still exists

Cash flow is not extinct. It is concentrated. RentalCalcs county data shows that 43 counties clear a 0.75% monthly rent-to-price ratio at the county median, and the geographic pattern is consistent: lower-priced counties in the Midwest, mid-South, and a handful of secondary Appalachian markets where prices never ran as hard.

What these markets share:

What they don't share with coastal markets:

The RentalCalcs market rankings score counties on actual cash flow at current rates and prices, not historical rules of thumb. The cash flow rankings sort by dollar cash flow per door at median price and rent with a 25% down, 30-year conventional assumption. Those rankings are where to start your geographic search, not a 1960s heuristic recirculated in investor forums.

Instead of applying a dead rule of thumb, run the actual numbers: the single-family calculator prices cash flow at real rates and real expenses in minutes, so you know exactly what a deal pencils to before you make an offer. The market data is there. Use it.
