What is a good GRM for rental property?
Most rental investors look for a GRM of 4 to 8, with lower being better. But ranges vary wildly by market: Memphis might run 5 to 7, while Austin is 12 to 16. A GRM that looks great in one city is mediocre in another, so always compare within the same market.
GRM is the fastest metric in real estate: price divided by annual gross rent. You can do it in your head from a listing in about three seconds, which makes it perfect for triaging a long list of properties. The trouble is that people treat it as a verdict when it is really just a filter. A low GRM is often great, sometimes a warning, and always incomplete without the expenses it ignores.
GRM ranges by city
These ranges reflect typical single-family rentals in each metro area. Your specific deal will vary, but these show what the market is pricing relative to rent:
| City / metro | Typical GRM | Notes |
|---|---|---|
| Cleveland, OH | 4 to 6 | Low prices, decent rents. Strong cash-flow territory. |
| Memphis, TN | 5 to 7 | Classic investor market. Lower GRMs common on B/C properties. |
| Indianapolis, IN | 6 to 8 | Affordable prices, steady rents. |
| Birmingham, AL | 5 to 7 | Similar profile to Memphis. |
| San Antonio, TX | 8 to 10 | Moderate. Prices have climbed faster than rents. |
| Tampa, FL | 8 to 11 | Insurance costs push effective expenses up even when GRM looks moderate. |
| Phoenix, AZ | 9 to 12 | Appreciation market pricing. Lower GRMs usually mean older or rougher areas. |
| Austin, TX | 12 to 16 | Expensive. Few deals clear the 1% rule. |
| Denver, CO | 13 to 17 | High prices relative to rent. Appreciation bet. |
| San Diego, CA | 15 to 20+ | Coastal premium. Cash flow is not the strategy here. |
A GRM of 6 in Cleveland is average. A GRM of 6 in Austin is a unicorn (or a problem property). Always benchmark against the local range, not a national number.
When a low GRM is a red flag
Counterintuitive but important: the lowest GRM on a list is not automatically the best deal. A suspiciously low GRM can signal:
- A tough neighborhood. The price is low because demand is low, and vacancy or turnover costs may eat the gross rent advantage.
- Inflated rent on the listing. The seller projects $2,000 but the market supports $1,500. The real GRM is 30% higher.
- Deferred maintenance. A cheap property with a failing roof, bad plumbing, or an aging electrical panel has capital costs the GRM does not show.
- High operating expenses. Two properties with the same GRM can have completely different cash flow if one has twice the property taxes or insurance. GRM is blind to expenses.
GRM and cap rate: the inverse relationship
GRM and cap rate answer similar questions from opposite directions. A low GRM usually corresponds to a high cap rate, and vice versa. For a deeper look at how the two metrics interact, see GRM vs cap rate. The key difference is that GRM uses gross rent (fast but crude) while cap rate uses net operating income (slower but truer).
If expenses run 45% of gross rent and the GRM is 8, the implied cap rate is roughly (1 - 0.45) / 8 = 6.9%. It is an approximation, but it shows why GRM works as a first screen: it correlates with cap rate closely enough to filter quickly.
Using GRM in your screening workflow
The practical use of GRM is speed. Like the 1% rule, GRM gives you a quick filter when you are scanning 50 listings and cannot run a full cap rate analysis on each. It lets you eliminate the obvious non-starters in seconds:
- Step 1: Calculate GRM from the listing (price ÷ annual rent).
- Step 2: Compare to the local market range. If it is at or below average, it gets a closer look.
- Step 3: On the shortlist, switch to cap rate, cash flow, and DSCR for the real analysis.
GRM is the filter. Cap rate, cash-on-cash, and DSCR are the decision.
Frequently asked questions
What is a good GRM for a rental property?
In cash-flow markets (Memphis, Cleveland, Indianapolis), 4 to 8 is typical. In balanced markets, 8 to 12. In appreciation markets like Austin or Denver, 12 to 17. Lower is generally better, but compare within the same market, not nationally.
Is a low GRM always a good sign?
Not always. A very low GRM can signal a tough neighborhood, inflated rent projections, or a property with expensive hidden problems. Always verify the rent against comparable properties and inspect the condition before assuming a low GRM means a good deal.
How does GRM relate to cap rate?
They are inversely related. A low GRM usually corresponds to a high cap rate, and vice versa. GRM uses gross rent (ignoring expenses), while cap rate uses net operating income. Cap rate is more accurate; GRM is faster.
Why does GRM ignore expenses?
By design. GRM is a screening tool, not an analysis tool. It trades accuracy for speed: you can calculate it from a listing in seconds without knowing the expense breakdown. That speed is the entire point, but it is also why you never make an offer on GRM alone.
Can I compare GRM across different cities?
You can, but it mostly tells you about pricing differences between markets, not which market is "better." A GRM of 6 in Memphis and 14 in Denver does not mean Memphis is the better investment. It means the two markets have fundamentally different price-to-rent profiles and strategies.
