Instantly evaluate any rental property investment. Calculate GRM, estimate fair market value, and compare properties in seconds.
GRM is one of the fastest ways to screen rental properties. Here's the three-step process every investor should know.
Start with the total purchase price of the property — this includes the listed price or your negotiated offer. Do not include financing costs at this stage.
Determine the total rent collected before expenses. Multiply monthly rent by 12, or use actual lease schedules for multi-unit properties for accuracy.
Divide property price by annual gross rent to get GRM. A lower number indicates a potentially better deal — compare with local market averages for context.
You can also rearrange this formula to estimate a property's fair market value: multiply the expected GRM for your area by the annual rent to get a price range.
Everything you need to quickly evaluate rental property opportunities — no spreadsheet required.
Get your GRM, gross yield, and estimated value in milliseconds. No sign-up, no waiting, no downloads required.
Our tool automatically interprets your GRM result — whether it's excellent, average, or a potential warning sign — based on standard investment benchmarks.
Enter your monthly or annual rent — we convert automatically. Ideal for quick property screenings during tours or open houses.
Works perfectly on any device. Calculate on your phone at a property showing, or on desktop during deeper research sessions.
See your gross yield percentage alongside GRM so you can compare properties using multiple metrics simultaneously.
No data stored, no account needed. All calculations happen in your browser. Completely free for unlimited use.
GRM benchmarks vary by market, property type, and condition. Use this as a starting guide — always compare with local comps.
| GRM Range | Rating | What It Means | Typical Market |
|---|---|---|---|
| Below 4 | Excellent | Strong cash-flow potential, very favorable price-to-rent ratio | Tertiary/Rural markets, distressed properties |
| 4 – 7 | Good | Solid investment, positive cash flow likely after expenses | Midwest, secondary cities, suburban markets |
| 7 – 10 | Average | Moderate returns; cash flow depends on financing and expenses | Mid-size cities, growing markets |
| 10 – 14 | Below Average | Lower yield; may rely on appreciation rather than income | Major metros, coastal cities |
| Above 14 | Caution | Low cash flow; heavily appreciation-driven investment thesis | NYC, San Francisco, premium locations |
Note: GRM is a screening metric only. Always supplement with cap rate, cash-on-cash return, and net operating income analysis before making investment decisions.
Deep dives into GRM, rental property analysis, and real estate investment strategy.
Learn everything about GRM — how it's calculated, when to use it, and how it compares to cap rate and other key metrics in rental property analysis.
Both GRM and cap rate measure real estate returns — but they tell very different stories. Find out which metric to prioritize and when to use both together.
Reverse-engineer the GRM formula to quickly estimate what a property should be worth based on local market GRM averages and current rental income.
GRM is a powerful screening tool — but misapplying it can lead to costly errors. Discover the five pitfalls that trap beginner and intermediate investors alike.
