The 1% Rule in Real Estate: Complete Guide for Rental Investors
Key Takeaways:
- The 1% rule states monthly rent should be at least 1% of the purchase price
- It's a quick screening tool, not a replacement for full analysis
- Many markets no longer meet the 1% rule due to price appreciation
- Use it to filter properties, then analyze Cash-on-Cash return for final decisions
The 1% rule is one of the most popular quick-screening tools in real estate investing. Used by thousands of investors to rapidly filter rental properties, this simple calculation helps you identify potentially profitable deals without spending hours on detailed analysis. But like any rule of thumb, it has limitations.
What is the 1% Rule?
The 1% rule is a guideline used by real estate investors to quickly evaluate rental properties. It states that the monthly rent of a property should be equal to or greater than 1% of the total purchase price (including any repairs needed).
The Formula:
Monthly Rent ≥ Purchase Price × 1%
Alternative View:
Rent-to-Price Ratio = Monthly Rent / Purchase Price ≥ 1%
Simple Example - Passes the 1% Rule:
- Purchase Price: $200,000
- Required Rent (1%): $2,000/month
- Actual Rent: $2,100/month
- Result: ✓ Passes (rent is 1.05% of price)
Example - Fails the 1% Rule:
- Purchase Price: $300,000
- Required Rent (1%): $3,000/month
- Actual Rent: $2,200/month
- Result: ✗ Fails (rent is only 0.73% of price)
Why Do Investors Use the 1% Rule?
The 1% rule became popular because it's a quick way to estimate if a property might generate positive cash flow. Here's the logic behind it:
Typical Monthly Expenses:
- • Mortgage payment: ~50% of rent
- • Property taxes: ~10% of rent
- • Insurance: ~5% of rent
- • Maintenance: ~5-10% of rent
- • Vacancy: ~5-8% of rent
- • Management: ~8-10% of rent
The Math Works Out:
If rent equals 1% of purchase price, and expenses consume ~85-90% of rent, you're left with approximately 10-15% cash flow.
This rough math suggests properties meeting the 1% rule should cash flow positively.
Important Note:
The 1% rule is a screening tool, not a guarantee of profitability. Interest rates, taxes, insurance costs, and HOA fees vary significantly by market and property. Always run full numbers before making investment decisions.
When the 1% Rule Works
The 1% rule is most useful in certain situations:
1. Initial Property Screening
When browsing hundreds of listings, the 1% rule helps you quickly eliminate properties that are unlikely to cash flow. This saves hours of detailed analysis on poor candidates.
2. Cash Flow-Focused Markets
In markets like Memphis, Cleveland, Indianapolis, and Kansas City, many properties still meet the 1% rule. These tend to be cash flow markets rather than appreciation markets.
3. Lower Price Point Properties
Properties under $150,000 are more likely to meet the 1% rule. Rent doesn't scale linearly with price - a $400,000 home won't rent for $4,000/month in most markets.
4. Multi-Family Properties
Duplexes, triplexes, and small apartment buildings often meet the 1% rule because combined rents are higher relative to purchase price.
When the 1% Rule Falls Short
The 1% rule has significant limitations that every investor should understand:
1. High-Cost Markets
In markets like San Francisco, Seattle, Austin, and Denver, virtually no properties meet the 1% rule. A $600,000 home won't rent for $6,000/month - more likely $2,500-3,500.
2. Ignores Appreciation
The rule focuses only on cash flow. Properties in high-appreciation markets may not meet 1% but could deliver excellent total returns through equity growth.
3. Doesn't Account for Expenses
Two properties meeting 1% could have vastly different cash flows if one has high property taxes, HOA fees, or insurance. The rule ignores these crucial variables.
4. Current Market Reality
Home prices have increased faster than rents in most markets since 2020. Many experienced investors now use 0.8% or 0.7% as more realistic thresholds.
Real Market Examples
| Market | Typical Price | Typical Rent | Rent-to-Price | Meets 1%? |
|---|---|---|---|---|
| Memphis, TN | $150,000 | $1,400 | 0.93% | Close |
| Indianapolis, IN | $180,000 | $1,600 | 0.89% | Close |
| Cleveland, OH | $120,000 | $1,200 | 1.00% | Yes |
| Austin, TX | $450,000 | $2,400 | 0.53% | No |
| Denver, CO | $550,000 | $2,800 | 0.51% | No |
| San Francisco, CA | $1,200,000 | $4,500 | 0.38% | No |
Better Metrics to Use Instead
While the 1% rule is useful for initial screening, these metrics provide more accurate analysis:
Cash-on-Cash Return
Measures your actual return on the cash invested. Accounts for financing, all expenses, and your down payment.
Target: 8-12% or higher
Cap Rate
NOI divided by purchase price. Shows return without financing, useful for comparing properties.
Target: 5-10% depending on market
DSCR (Debt Service Coverage)
NOI divided by annual debt payments. Shows if property income covers the mortgage.
Target: 1.25+ (lenders often require this)
Total ROI
Includes cash flow + appreciation + equity paydown + tax benefits for complete picture.
Target: 15-25% annually
How to Apply the 1% Rule in Your Analysis
Use as First Filter
When browsing listings, quickly calculate rent-to-price ratio. Eliminate properties below 0.7-0.8% unless you're specifically targeting appreciation markets.
Run Full Numbers on Promising Properties
For properties passing initial screening, calculate actual Cash-on-Cash return with all expenses included.
Adjust for Your Market
In expensive markets, you may need to accept 0.6-0.7% and rely more on appreciation. In cash flow markets, hold out for 1%+.
Consider Your Strategy
If you need immediate cash flow, the 1% rule matters more. If you're building long-term wealth through appreciation, it's less critical.

Summary: Should You Use the 1% Rule?
Yes, but with limitations. The 1% rule is a useful first filter for quickly screening rental properties. However:
- • Don't rely on it exclusively - always run full cash flow analysis
- • Adjust your threshold based on market conditions (0.7-0.8% may be realistic)
- • Consider appreciation potential alongside cash flow
- • Use modern tools like Smart Rental Investor to automate analysis
