What Is a Good Gross Rent Multiplier? Benchmarks by Market and Property

A good gross rent multiplier is one at or below what comparable rentals in the same market have recently sold for. Lower means more rent per dollar of price. There is no universal number, because a GRM of 10 is a fair price in Charlotte and a steal in San Jose.

Nationally, most residential rentals trade between 8 and 12. Where a property should fall inside that range depends on its market, its type and its condition.

The bands

Under 6. Very low. Under six years of gross rent to equal the price. Found in the cheapest markets, on small-town and rural property, and on rough housing stock. Sometimes it signals a rent figure that will not hold up or a neighborhood with real risk. Cash flow is strong on paper.

6 to 8. Low. This is where the 1% rule sits (a GRM of 8.3). Properties here typically cover a 30-year loan with 20 to 25% down and produce positive cash flow after expenses. Common in the low-cost Midwest and South and in secondary markets.

8 to 12. Typical. Most US metros. Income is real but the margin after expenses and a mortgage is thin at current interest rates. Whether a property here cash flows depends on taxes, insurance and the rate more than on the rent.

12 to 16. High. Appreciation markets: much of the West Coast, the Northeast corridor, Denver, Austin at their peaks. A financed purchase will not cover its payment without a large down payment. Buyers are paying for growth.

16 and above. Very high. Premium coastal pricing. Rent is a small fraction of price and the investment case is almost entirely appreciation and land value.

Each band has a page with the rent and implied cap rate behind it. See GRM of 8, GRM of 10 or GRM of 12.

What each band means for cash flow

Under typical expenses (5% vacancy, 36% of collected rent for operating costs), GRM maps to cap rate roughly as 0.61 divided by GRM:

GRM	Implied cap rate	Financed at 7.25%, 25% down
6	10.1%	Strong positive cash flow
8	7.6%	Modest positive cash flow
10	6.1%	Break-even to slightly negative
12	5.1%	Negative
16	3.8%	Clearly negative

A 30-year loan at 7.25% costs about 8.2% of the balance each year in payments. A property has to yield more than that on its NOI for borrowed money to help. That line falls at a GRM around 7.5 under these assumptions. Above it, leverage hurts; the GRM vs cap rate guide covers the mechanics.

Why the benchmark moved

Between 2012 and 2021, a GRM of 10 usually cash flowed. Mortgage rates were 3 to 4%, so a loan cost about 5 to 6% of the balance a year in payments, and a 6% cap rate cleared it.

At 7% rates, the same GRM of 10 does not. The property did not change. The cost of money did, and the GRM that counts as “good” for a financed buyer dropped by two to three points. Investors who learned the 1% rule in 2015 as a comfortable target now find it is the minimum for cash flow.

Why multipliers differ by market

GRM is a price. Buyers pay more years of rent for property they expect to appreciate and for tenants they expect to stay. They pay fewer years of rent where they expect more turnover, more repairs and less growth.

That means a low GRM is not free. It usually comes with older stock, weaker demand or a rougher neighborhood. The question to ask about a GRM of 6 is what the market knows that you do not.

Why multipliers differ by property type

Within one market, GRM steps down as management intensity rises and steps up as resale ease rises.

Single-family homes trade highest, because owner-occupants compete for them on resale and they turn over less.

Two to four unit properties trade half a point to a point lower.

Condos vary with HOA dues. High dues do not show up in GRM at all, which is the biggest single reason GRM misleads on condos. A condo at a GRM of 10 with $400 monthly dues has the cap rate of a house at a GRM of 12.

Short-term rentals are priced by a different buyer pool and often do not trade on GRM in any meaningful way.

Setting your own number

Pull recent sales of similar property in the submarket and compute GRM on each. That cluster is the market GRM. A listing below it is cheap or has a problem. A listing above it is priced for something the rent does not show.

Then set a ceiling from your financing. If you need the property to cover itself with 25% down at today’s rates, you need a GRM around 7.5 or lower under typical expenses, and lower still in high-tax states. If you are buying for appreciation and can carry negative cash flow, a higher GRM may be fine.

The calculator shows the GRM on your numbers, the cap rate it implies, and the price or rent that hits your ceiling.
