The 1% rule for rental property: does it still work in 2026?

What the 1% rule actually says

The rule is one division: take the gross monthly rent, divide by the purchase price, and check whether the result is 1% or more.

Monthly rent ÷ purchase price ≥ 1%.

Flip it around and it becomes a price ceiling: the most you should pay is 100 × the monthly rent. A house that rents for $1,800/month "passes" at any price up to $180,000; one that rents for $2,500 passes up to $250,000. That is the whole mechanic — no financing, no expenses, no condition. Which is the point: the 1% rule exists to kill obviously bad listings in seconds so you only spend real time on the survivors. Run a few through the 1% rule calculator and you'll feel how brutally fast the filter is.

A 60-second screen: three listings

Say you pull three properties off the MLS on a Saturday morning:

Listing A — a $220,000 single-family home renting for $2,200/month. Ratio: $2,200 ÷ $220,000 = 1.00%. Passes.
Listing B — a $250,000 duplex pulling $2,600/month across both units. Ratio: 1.04%. Passes.
Listing C — a $350,000 house in a nicer suburb renting for $2,400/month. Ratio: 0.69%. Fails.

Two pass, one fails, in under a minute and without a calculator app. Notice the pattern already forming: the cheaper, blue-collar properties clear the bar, and the pricier suburban house — the one that will probably appreciate fastest — doesn't come close. That tension between cash flow and appreciation is the rule's entire personality. The 1% rule is the opening move in the 60-second underwrite, not the closing argument.

Where the 1% comes from — it's really a rent-to-price ratio

The 1% threshold isn't magic; it's a proxy. The idea is that if gross rent is about 1% of price each month — 12% of price a year — there's usually enough income to cover the mortgage, taxes, insurance, vacancy, and repairs with a little left over, at the interest rates that were normal when the rule caught on. It is a rent-to-price ratio dressed up as a pass/fail test.

That makes it a cousin of the gross rent multiplier. Watch the algebra: if price = 100 × monthly rent, then price = 100 ÷ 12 = 8.3 × annual rent. So "passes the 1% rule" is the same statement as "has a gross rent multiplier of about 8.3 or lower." (The 100 is the price-to-monthly-rent multiple; the GRM you'll see quoted uses annual rent, which is why the two numbers look so different.) If you prefer thinking in GRM, the GRM calculator gets you to the same screen from the other direction.

The 2026 problem: the bar quietly moved

Here is the part most "1% rule" articles skip. The rule uses a fixed yardstick — 1% — to measure something that moves with interest rates. When the cost of debt doubles, the rent-to-price ratio you need just to break even moves with it.

Work it per $100,000 of price, with 25% down, taxes at 1.2%, insurance around 0.6% of value, and 15% of rent set aside for vacancy and reserves (self-managed, no property manager):

At a 3.5% loan (the 2021 world): principal and interest on the $75,000 borrowed run about $337/month, plus $150 of taxes and insurance — roughly $487 of fixed carry. Cover that plus reserves and you break even at about 0.57% rent-to-price.
At a 7% loan(2026 investment-property pricing): P&I on the same $75,000 jumps to about $499/month, plus the same $150 — about $649 of fixed carry. Break-even climbs to roughly 0.76% rent-to-price.

So the floor moved from ~0.57% to ~0.76% purely because rates changed. A property at the full 1% still cash-flows — but the cushion between "passes the rule" and "loses money" shrank from a comfortable 0.43 points to a thin 0.24. The deals that quietly broke in this shift are the 0.7–0.8% properties that gushed cash at 3.5% and now barely tread water. This is the same negative-leverage trap that makes a once-safe cap rate look fine and still lose to the loan constant. The 1% rule didn't get wrong — the world underneath it moved, and the rule, being a fixed number, didn't notice.

Passing the 1% rule is not the same as a good return

Even when a property clears 1%, the rule says nothing about how good the return is — because it never looks at the costs that vary most between properties. Take two homes that both hit exactly 1%:

Property X: $150,000, rents for $1,500/month, in a state with a 0.85% property-tax rate.
Property Y: $300,000, rents for $3,000/month, in a state with a 1.8% property-tax rate.

Both pass the screen identically. But underwrite them with 25% down at 7%, self-managed, with 5% vacancy and 10% for maintenance and capital reserves:

Property Xcarries about $954 of PITI ($748 P&I + $106 taxes + $100 insurance) plus $225 of reserves — roughly $1,179 against $1,500 rent, or +$321/month. On about $42,000 all-in (down payment plus closing), that's a ~9% cash-on-cash return.
Property Ycarries about $2,097 of PITI ($1,497 P&I + $450 taxes + $150 insurance) plus $450 of reserves — roughly $2,547 against $3,000 rent, or +$453/month. But on about $84,000 all-in, that is only a ~6.5% cash-on-cash return.

Same ratio, returns nearly 40% apart — driven mostly by a property-tax line the 1% rule never reads. That is why you finish the job with the metric that actually accounts for your cash: cash-on-cash. If you're fuzzy on which metric answers which question, the guide on cap rate vs cash-on-cash vs DSCR draws the lines.

What the rule ignores — both halves of the fraction

The numerator and the denominator both hide traps.

The denominator should be all-in cost, not list price. On a fixer or a BRRRR deal, a $120,000 house that needs $40,000 of work and then rents for $1,400 looks like a screaming 1.17% against the purchase price — but against your true $160,000 all-in, it's 0.875% and fails. Always run the rule on price plus rehab, or it will flatter a property you haven't finished paying for.

The numerator should be real market rent, not the listing's hopeful number.Sellers and pro formas quote rents that are often 5–15% above what the unit will actually fetch. Pull comps before you trust a rent figure, because a 10% haircut on rent drops a 1.0% property straight to 0.9%. And the rule is silent on everything that decides whether you keep that rent: condition, tenant quality, neighborhood trajectory, the interest rate on your specific loan, and how much you put down. A ratio can't see any of that.

1% vs 2% rule, and what's realistic in 2026

The 2% rule is the same test with the bar doubled: monthly rent of at least 2% of price — a $100,000 house renting for $2,000. In 2026 that is effectively extinct outside deep-discount, low-value, or management-intensive properties. When a listing genuinely clears 2%, it's usually telling you something — a rough block, deferred capex, or a rent number that won't survive a real lease-up — not that you've found a unicorn.

Where do 1% deals actually live now? Overwhelmingly in the Midwest and South, and in the sub-$200,000 price tiers — Ohio, Indiana, Alabama, parts of Texas and the Carolinas. In coastal and high-growth metros (San Diego, Denver, Austin, Seattle), most rentals pencil at 0.4–0.6%, and investors there are explicitly betting on appreciation rather than monthly cash flow. Neither approach is wrong; they're different games, and the 1% rule is only scoring one of them. If cash flow isn't your goal, a failing ratio isn't a verdict.

How to use the 1% rule without getting burned

Treat it as the first gate, not the decision. A practical workflow:

Screen fast.Run the ratio on every listing. In 2026's rate environment, give yourself margin — treat 1.0% as the floor for a cash-flow deal, not the target, since break-even already sits near 0.76%.
Use all-in cost and real rent. Price plus rehab on the bottom, comped market rent on top.
Then actually underwrite the survivors. Layer in full PITI, vacancy, maintenance, capital reserves, and management, and check cash-on-cash and DSCR before you write an offer. A deal that passes the 1% rule and then clears a real underwrite is worth pursuing; one that passes only the ratio is worth a second look, not a check.

That last step is the whole reason TrueCap exists. Drop in a price and a rent and the free analyzer pulls a current rate, estimates taxes and insurance from the address, layers in vacancy and reserves, and hands back cash flow, cap rate, cash-on-cash, DSCR, and a plain-English verdict — the entire underwrite the 1% rule was only ever pretending to be a stand-in for. The rule is the napkin; this is the spreadsheet.

FAQ

What is the 1% rule in real estate?

The 1% rule is a screening shortcut that says a rental's gross monthly rent should be at least 1% of its purchase price. A $200,000 property would need to rent for $2,000/month to pass. Rearranged, it caps your price at 100 times the monthly rent. It is a triage filter, not an underwrite — it tells you which listings are worth a closer look, not whether a deal actually makes money once taxes, insurance, vacancy, and financing are in the picture.

Does the 1% rule still work in 2026?

As a quick filter, yes — but with two caveats. First, higher rates raised the bar: at a 7% investment-property rate, a typical financed rental breaks even at roughly 0.76% rent-to-price, versus about 0.57% back when loans were 3.5%, so a 1% deal cash-flows on a thinner margin than it used to. Second, 1% deals have gotten scarce in appreciation and coastal markets, where many listings sit at 0.4–0.6%. The rule still works, but passing it is now necessary, not sufficient.

What's the difference between the 1% rule and the 2% rule?

Same formula, higher bar. The 2% rule wants monthly rent of at least 2% of price — a $100,000 house renting for $2,000/month. In 2026 that is essentially extinct outside deep-discount, low-value, or heavy-management properties (think sub-$80k homes in soft markets), and a listing that clears 2% usually signals a rough neighborhood, heavy capex, or a rent number that won't hold. Most investors today treat 1% as the aspirational screen and anything above it as a flag to look harder, not a green light.

Does the 1% rule use rent before or after expenses?

Gross rent, before any expenses, against the purchase price. That is exactly why it can mislead: two properties can both hit 1% and throw off very different cash flow once you account for property tax (which ranges from under 0.5% to over 2.2% of value by state), insurance, HOA dues, and condition. For a fixer or BRRRR deal, use your all-in cost — price plus rehab — as the denominator, or the rule will flatter a property you haven't finished paying for.

Is a property that fails the 1% rule always a bad deal?

No. The 1% rule is blind to appreciation, rent growth, tax benefits, and below-market rents you can raise. Plenty of properties in strong appreciation markets sit at 0.6–0.8% and still win over a 10-year hold on equity growth and forced appreciation. The rule is a cash-flow screen, so it's most useful when cash flow is your goal. If your thesis is appreciation or a value-add, run the full underwrite and don't let a single ratio veto the deal.

The bottom line

The 1% rule earns its fame: it's the fastest honest screen in real estate, and on a cheap, cash-flow-market rental it still flags the right deals in seconds. But it's a rent-to-price ratio with a fixed threshold in a world where rates move, and in 2026 the break-even floor has crept up to roughly 0.76%, leaving far less daylight between "passes" and "bleeds." Use it to decide what to look at, never what to buy. Screen on all-in cost and real rent, then run the survivors through a full underwrite — PITI, reserves, cash-on-cash, and DSCR — and the 1% rule goes back to doing the one job it's good at: getting you to a "maybe" fast.
