GRM is a quick screen (price ÷ gross rent). It doesn’t account for expenses or financing — use NOI/DSCR for deeper underwriting.

How this calculator works

GRM (Gross Rent Multiplier) is a fast screening metric: purchase price divided by gross annual rent. It’s a quick way to compare rental deals before you dig into expenses.

What it includes
  • Gross annual rent
  • GRM
  • Price at a target GRM
How to use it
  1. Enter purchase price and expected monthly rent.
  2. Use GRM to quickly compare similar properties in the same market.
  3. Then validate the deal with NOI, DSCR, and cash flow (GRM ignores expenses).

FAQ

Does GRM include expenses?
No. GRM uses gross rent only. It’s a fast screen, but it can be misleading if taxes, insurance, or HOA costs are high.
What’s a “good” GRM?
It varies by market. Use GRM to compare similar deals in the same area and then confirm with NOI and DSCR.
