The 1% Rule in Real Estate: Does It Still Work?
The 1% rule says monthly rent should be at least 1% of purchase price. Learn when it works, when it fails, and what metrics to use instead in today's market.
The 1% rule is one of the most widely cited screening tools in real estate investing. It states that a rental property’s monthly gross rent should be at least 1% of the purchase price. A $200,000 property should rent for at least $2,000 per month.
It is fast, simple, and easy to apply when scrolling through listings. It is also increasingly difficult to find properties that meet it, and many investors are abandoning it entirely. This guide explains what the rule actually tells you, where it still works, and what to use when it does not.
The 1% Rule Formula
Monthly Rent / Purchase Price >= 1%
Or equivalently:
Purchase Price x 0.01 ≤ Monthly Rent
| Purchase Price | Minimum Rent (1%) |
|---|---|
| $100,000 | $1,000 |
| $150,000 | $1,500 |
| $200,000 | $2,000 |
| $300,000 | $3,000 |
| $400,000 | $4,000 |
Properties that meet or exceed the 1% rule are generally considered worth further analysis. Properties below 0.7-0.8% are typically dismissed.
Some investors use a more aggressive 2% rule ($200,000 property renting for $4,000/month), which virtually guarantees strong cash flow but only exists in very low-value or very high-risk markets.
What the 1% Rule Actually Measures
The 1% rule is a proxy for the rent-to-price ratio, which correlates loosely with cash flow potential. It does not account for:
- Operating expenses (which vary wildly by market)
- Interest rates and financing terms
- Property taxes (a $200K property in Texas pays 3x the taxes of one in Colorado)
- Insurance costs
- Vacancy rates
- Capital expenditure needs
This is why the 1% rule is a screening tool, not an underwriting tool. It tells you whether a property is worth running full numbers. It does not tell you whether the property is actually profitable.
Worked Example: 1% Rule Property
Property A — Meets the 1% Rule
| Item | Amount |
|---|---|
| Purchase price | $150,000 |
| Monthly rent | $1,500 (1.0%) |
| Down payment (25%) | $37,500 |
| Loan amount | $112,500 |
| Interest rate | 7.0% |
| Monthly P&I | $749 |
Annual income and expense analysis:
| Line Item | Annual |
|---|---|
| Gross rent | $18,000 |
| Vacancy (8%) | -$1,440 |
| Property taxes | -$2,400 |
| Insurance | -$1,200 |
| Management (8%) | -$1,325 |
| Maintenance (1%) | -$1,500 |
| CapEx (0.5%) | -$750 |
| NOI | $9,385 |
| Debt service | -$8,988 |
| Cash flow | $397 |
Cash-on-cash return: $397 / $43,500 (down + closing) = 0.9%
Even at exactly 1%, the deal barely cash flows with 7% interest rates. Five years ago, with rates at 4%, the same property produced roughly $3,300/year in cash flow (7.6% cash-on-cash).
Worked Example: Below 1% Rule Property
Property B — 0.7% Ratio
| Item | Amount |
|---|---|
| Purchase price | $300,000 |
| Monthly rent | $2,100 (0.7%) |
| Down payment (25%) | $75,000 |
| Loan amount | $225,000 |
| Interest rate | 7.0% |
| Monthly P&I | $1,497 |
| Line Item | Annual |
|---|---|
| Gross rent | $25,200 |
| Vacancy (5%) | -$1,260 |
| Property taxes | -$3,600 |
| Insurance | -$1,800 |
| Management (8%) | -$1,915 |
| Maintenance (1%) | -$3,000 |
| CapEx (0.5%) | -$1,500 |
| NOI | $12,125 |
| Debt service | -$17,964 |
| Cash flow | -$5,839 |
Deeply cash flow negative. At 0.7%, the property requires significant appreciation or rent growth to generate a positive total return. This is typical of many coastal and high-growth markets.
Where the 1% Rule Still Works
The 1% rule remains achievable in certain market types:
- Midwest metros — Cleveland, Indianapolis, Memphis, Kansas City, St. Louis. Median home prices $150K-$250K with rents that often meet or exceed 1%.
- Southeast secondary markets — Birmingham, Jackson (MS), Little Rock. Similar dynamics.
- Small multifamily (2-4 units) — Duplexes and triplexes often hit 1% because total rent from multiple units is measured against a single purchase price.
- Value-add properties — Buy below market, renovate, and rent at market rate. The effective rent-to-price ratio on your invested cost may exceed 1% even if the post-renovation market value falls below it.
Where the 1% Rule Fails
High-Cost Markets
In markets where median home prices exceed $400K, finding 1% properties is nearly impossible without going into war zones. A $500,000 home in Austin renting for $5,000/month does not exist in any desirable neighborhood.
High-Tax Markets
Property taxes in Texas, New Jersey, and Illinois can run 2-3% of assessed value annually. A property might hit the 1% rent threshold but still lose money because taxes consume 20-30% of gross rent.
High-Rate Environments
The 1% rule was popularized when mortgage rates were 3.5-5%. At 7%+ rates, debt service is 40-60% higher for the same loan amount. Properties that cash flowed at 1% in 2020 are negative cash flow today.
| Scenario | Rate | Monthly P&I ($150K loan) | Annual Cash Flow |
|---|---|---|---|
| 2020 | 3.5% | $673 | $4,297 |
| 2022 | 5.5% | $852 | $2,153 |
| 2024 | 7.0% | $998 | $389 |
| 2026 | 7.0% | $998 | $397 |
The same 1% property went from $4,300+ cash flow to under $400 purely from rate changes.
Better Metrics to Use Instead
The 1% rule served as a quick filter when rates were low and expenses were predictable. In today’s environment, you need metrics that account for financing and actual expenses.
Cash-on-Cash Return
Annual Cash Flow / Total Cash Invested
This is the most practical measure of a deal’s return on your actual out-of-pocket investment. It accounts for financing terms, which the 1% rule ignores. Target 6-10%+ depending on your market and risk tolerance.

Gross Rent Multiplier (GRM)
Purchase Price / Annual Gross Rent
GRM is the inverse of the 1% rule, expressed annually. A 1% property has a GRM of 8.3. Lower is better. GRM has the same limitations as the 1% rule (ignores expenses) but is more commonly used by commercial investors and appraisers.
See our full GRM guide.
Cap Rate
NOI / Purchase Price
Cap rate strips out financing and measures the property’s return as if purchased with all cash. It accounts for operating expenses, unlike the 1% rule. Cap rates of 6-8% generally indicate solid cash flow potential.

Should You Still Use the 1% Rule?
Yes, but only as a first-pass filter — and adjust the threshold for current conditions.
A practical approach for 2026:
- 0.8%+ in low-tax states: Worth running full numbers
- 0.9%+ in high-tax states: Worth running full numbers
- 1.0%+: Strong candidate, run numbers immediately
- Below 0.7%: Skip unless you are specifically investing for appreciation
The 1% rule has not stopped being useful. It has stopped being sufficient. Use it to narrow your search, then use cash-on-cash return and full deal analysis to make actual decisions.
Frequently Asked Questions
Is the 1% rule realistic in 2026?
In most major metro areas, no. Median home prices have outpaced rent growth for years, pushing the average rent-to-price ratio well below 1%. The rule remains achievable in Midwest and Southeast markets with lower home prices and in small multifamily properties.
What is a good rent-to-price ratio if not 1%?
In the current environment, 0.8% or above generally indicates a property worth analyzing further. Many successful investors are buying at 0.7-0.8% and generating acceptable returns through a combination of modest cash flow, principal paydown, and appreciation.
Does the 1% rule apply to multifamily properties?
Yes, and multifamily properties are more likely to meet it. A duplex purchased for $250,000 that rents for $1,300 per side ($2,600 total) hits 1.04%. The combined rent of multiple units makes the math more favorable.
Should I use the 1% rule for Airbnb properties?
No. Short-term rental revenue is 1.5-2.5x higher than long-term, but expenses are also 2-3x higher. A property at 1.5% on STR revenue might barely break even after cleaning, utilities, furnishing, and platform fees. Use gross revenue and a full expense analysis instead.
What replaced the 1% rule?
Nothing has “replaced” it as a screening tool because no other metric is as fast to calculate in your head. The best practice is to use the 1% rule (with adjusted thresholds) for initial screening, then immediately validate with cash-on-cash return and a full income/expense analysis.
