Gross Rent Multiplier Formula
What This Means
A sample property priced at $385,000 with $2,850/month rent has a gross rent multiplier of 11.26x. GRM is the fastest back-of-napkin screening tool in real estate. If similar properties in a market sell at 10x GRM and you find one at 8x, it may be undervalued. But always dig deeper — a low GRM might also signal high expenses or deferred maintenance.
Where This Value Comes From
Gross Rent Multiplier is not entered directly — it is calculated from Gross Potential Rent and Purchase Price. See the formula breakdown above and the detailed inputs below.

Detailed Explanation
