The 1% rule and the 2% rule get talked about like two different tools. They aren't. They're the same measurement — monthly rent as a fraction of purchase price — with the bar set at two different heights. Understanding that they're one screen with two settings is the whole game, because it tells you exactly when each one is useful and when it's quietly lying to you. This post works both bars with illustrative 2026 numbers, shows you the cap-rate and gross rent multiplier math hiding underneath them, and lands on which one you should actually screen with.
The two rules, in one sentence each
The 1% rule says a rental's gross monthly rent should be at least 1% of the purchase price. The 2% rule doubles that: monthly rent should be at least 2% of the price. Both are pass/fail filters you can run in your head on a listing before you open a spreadsheet.
On a $200,000 property, the 1% rule wants $2,000/month in rent. The 2% rule wants $4,000/month for the exact same building. That's the entire difference — a factor of two on the same ratio. Everything else in this post is a consequence of that gap.
The ratio underneath both: GRM and cap rate
Rent-to-price is just the gross rent multiplier flipped over. A 1% monthly ratio is a 12% annual gross yield, which is a GRM of about 8.3 (100 ÷ 12). A 2% monthly ratio is a 24% annual gross yield — a GRM of about 4.2. Buying at a 4.2 GRM means the property's gross rent pays back the purchase price in roughly four years, before expenses. That alone should tell you how rare a true 2% property is.
The bridge to profitability runs through the cap rate. A useful approximation:
At a 50% expense ratio — the 50% rule benchmark — a 1% property pencils to a 6% cap rate ((1 − 0.50) × 12%), while a 2% property implies a 12% cap rate ((1 − 0.50) × 24%). Both of those are gross approximations, but they frame the stakes: the 1% rule is aiming at an ordinary, financeable cash-flow deal; the 2% rule is aiming at a yield that, in 2026, only distressed or deeply unglamorous property produces.
What each bar demands by price tier
The rules feel abstract until you attach dollar rents to them. Here is what the 1% and 2% bars ask for across three common price points, next to illustrative rents for each price point (your local rent comps will differ):
| Price | 1% rent target | 2% rent target | Illustrative rent | Which bar it clears |
|---|---|---|---|---|
| $100,000 | $1,000 | $2,000 | ~$1,100 | Clears 1%, misses 2% |
| $250,000 | $2,500 | $5,000 | ~$2,000 | Misses both (marginal on 1%) |
| $450,000 | $4,500 | $9,000 | ~$2,700 | Misses both badly |
The pattern is the story. In cheaper, cash-flow-oriented markets the 1% rule can still be a live screen. In median and appreciation markets even the 1% bar is a stretch, and the 2% bar is science fiction: a $450,000 house renting for $9,000 a month doesn't exist in a normal neighborhood. The 2% rule isn't wrong; it's just describing a corner of the market most investors never shop in.
The national numbers point the same way. In the Census Bureau's 2020-2024 American Community Survey, renters paid a median of $1,413 a month and the median home value was $332,700 — rent of about 0.42% of value per month. Those two medians describe different homes, so treat the ratio as a rough gauge, but it sits well under even the 1% bar and under a quarter of the 2% bar.
A same-dollar worked comparison
Abstract ratios hide the trade-off. Let's underwrite two illustrative deals that each sit right on their respective rule, both financed at 25% down, 7%, 30 years, so you can see what “passing 2%” actually buys you — and what it costs.
Deal A — a 1% property at $250,000
A $250,000 duplex renting for $2,500/month ($30,000/year) hits the 1% rule exactly. You put $62,500 down and finance $187,500. At 7% over 30 years the payment is about $1,247/month($14,969/year). (Size any loan with the mortgage payment calculator.) Run expenses at roughly 50% of rent — $15,000/year — and net operating income lands near $15,000. That's a 6% cap rate, right on the approximation. Cash flow after the mortgage is about $31/year — call it breakeven — for a cash-on-cash return near 0%.
Deal B — a 2% property at $75,000
A $75,000 house in a class-C, cash-flow market renting for $1,500/month ($18,000/year) hits the 2% rule. You put $18,750 down and finance $56,250. The payment is about $374/month ($4,491/year). But cheaper properties in weaker neighborhoods can run higher expense ratios — more turnover, more repairs, more delinquency — so this example assumes 58%: $10,440/year. NOI is about $7,560, a 10.1% cap rate, and cash flow after the mortgage is roughly $3,069/year ($256/month). On $18,750 invested that's a 16.4% cash-on-cash return.
| Metric | Deal A · 1% · $250K | Deal B · 2% · $75K |
|---|---|---|
| Rent-to-price | 1.0% | 2.0% |
| Expense ratio | 50% | 58% |
| Cap rate | 6.0% | 10.1% |
| Monthly cash flow | ~$3 | ~$256 |
| Cash-on-cash | ~0% | ~16.4% |
On the numbers alone, the 2% deal buries the 1% deal — higher cap rate, real cash flow, a double-digit cash-on-cash return. So why doesn't everyone chase 2% properties? Because the spreadsheet doesn't price the risk.
Why the 2% rule is nearly extinct
A 2% rent-to-price ratio is a market's way of telling you why the property is cheap. Properties that rent for 2% of a low price often sit in neighborhoods with soft appreciation, higher tenant turnover, more deferred maintenance, and thinner buyer demand when you go to sell. The “10% cap rate” is real, but so is the vacancy month you didn't model, the $9,000 roof on a $75,000 house (that's 12% of the purchase price in one repair), and the property manager who won't take the account. Class-C cash flow is a job, not a coupon.
There's also a simple math reason the 2% rule went quiet. In the cheap-money era, a 2% property financed at 4% threw off enormous leveraged returns, so investors evangelized the rule. At 2026 borrowing costs the deals that clear 2% are scarcer, and the ones that exist come with the risk profile above. The rule didn't stop working — the market that produced it thinned out.
Why even the 1% rule needs an asterisk in 2026
The 1% rule is the one you'll actually use, but 7% rates moved its meaning (Freddie Mac's weekly 30-year fixed average was 7.03% on September 24, 2026). Break-even rent-to-price — the ratio at which a leveraged property covers its mortgage and operating costs with nothing left over — has climbed to roughly 1.0% (25% down, 50% expense ratio) at today's rates. That means a property sitting exactly at 1.0% is right at breakeven, not the comfortable buffer the rule implied when money was cheap. Deal A above makes the point: a textbook 1% property that cash-flows about three dollars a month.
So the 1% rule in 2026 is a “keep looking” line, not a “buy” line. Clearing it means the deal is worth a full underwrite; it does not mean the deal is good. For the deeper dive on how the rule shifted and the two 1% properties whose returns sit 40% apart, see our full breakdown of the 1% rule.
The blind spot both rules share
Here's the trap that sinks investors who lean on either rule: both compare gross rent to price and ignore every expense. Two properties can hit the identical rent-to-price ratio while one cash flows and the other bleeds, because one has $2,800 taxes and the other $6,000, or one needs $400/month in capital reserves and the other $150. The rule can't see any of that. It's a first-pass filter — a way to decide what's worth underwriting — and nothing more.
The fix is to treat the screen and the underwrite as two separate steps. Run the 1% rule (or the 2% rule, if you shop that niche) to triage a list of listings down to a shortlist. Then take the survivors to real net operating income — rent minus vacancy, taxes, insurance, maintenance, management, and reserves — and judge them on cap rate, cash-on-cash, and DSCR instead.
Which rule should you use?
For almost everyone: the 1% rule as a daily screen, the 2% rule as a label. The 1% rule maps to the ordinary financeable cash-flow deal most investors are hunting, and it's calibrated close enough to today's break-even that clearing it actually means something. The 2% rule is best understood not as a target you'll hit but as a description of a specific, higher-risk corner of the market — useful vocabulary, not a filter you'll run on Zillow and get results from.
Whichever you reach for, remember what the rule is: a five-second triage that tells you where to spend your next hour. It never tells you whether to buy. That answer lives in the full underwrite. You can run either screen instantly here — 1% rule calculator and 2% rule calculator — and then take the ones that pass to the full analyzer.
FAQ
What is the difference between the 1% rule and the 2% rule?
They are the same rent-to-price screen at two different bars. The 1% rule says a rental's monthly rent should be at least 1% of the purchase price; the 2% rule doubles that bar to 2%. On a $150,000 property, the 1% rule wants $1,500/month and the 2% rule wants $3,000/month. The 2% rule is far stricter, and in 2026 almost nothing in a normal market clears it.
Does the 2% rule still work in 2026?
As a filter it still 'works', but almost no property passes it anymore. A 2% rent-to-price ratio implies a gross rent multiplier of about 4.2 and a cap rate near 12% at typical expenses — numbers you only see in deeply distressed, low-price, high-risk markets. For the overwhelming majority of listings the 2% rule just returns 'no', so it stops being useful as a screen.
Is the 1% rule still realistic with 7% mortgage rates?
Only as a floor, and only in cash-flow markets. At today's roughly 7% mortgage rates, with 25% down and half of rent going to operating costs, break-even rent-to-price sits around 1.0% before you clear a dollar of profit, so a property that exactly hits 1% only breaks even — a reason to underwrite, not a slam dunk. In high-price appreciation metros, where monthly rent is often well under 1% of price, the 1% rule fails almost everything — which is a signal about the market, not necessarily a reason to skip it.
Which rule should I use to screen deals?
Use the 1% rule as your everyday triage in most markets and treat the 2% rule as a label for a specific, higher-risk niche rather than a target. The rule is only a screen: it tells you what to underwrite next, never whether to buy. A property can pass the 1% rule and still lose money once real vacancy, maintenance, management, and capital reserves show up.
What cap rate does the 1% rule imply?
About 6% at a 50% operating-expense ratio. Cap rate roughly equals (1 − expense ratio) × annual gross yield, and the 1% rule is a 12% annual gross yield (1% a month × 12). So (1 − 0.50) × 12% = 6%. The 2% rule doubles the gross yield to 24% and implies roughly a 12% cap rate at the same expense ratio.
Do these rules include operating expenses?
No — that's their biggest blind spot. Both rules compare gross rent to price and ignore taxes, insurance, vacancy, maintenance, management, and capital expenditures entirely. That's why two properties can hit the identical rent-to-price ratio and one cash flows while the other bleeds. Always follow the screen with a real underwrite on net operating income.
