Quick screening metric to compare deals across markets.

What it does

Divides the purchase price by annual gross rent to produce a multiple. Lower multiples indicate more income per dollar of price.

Why it matters

GRM is a fast first filter. A GRM above 15–20 in most markets signals a potentially overpriced property before you run a full analysis.

How to Use

  1. 1
    Enter purchase price: The total acquisition cost.
  2. 2
    Enter annual gross rent: Monthly rent × 12.
  3. 3
    Compare to local market GRMs: A lower GRM is better. Use rental comps to estimate realistic gross rent.

Best Practices & Benchmarks

  • GRM benchmarks vary widely by market: under 8 is typically strong cash flow territory; 10–15 is moderate; above 15–20 suggests the property may be overpriced for income.
  • Always use actual or achievable market rents — not seller-provided rents, which may include lease-up incentives or above-market tenants.
  • Compare GRM to local comps, not national benchmarks. In high-cost coastal cities, a GRM of 20+ may be normal; in the Midwest, 10+ may be high.
  • GRM ignores vacancy, expenses, and debt service — two properties with identical GRMs can have dramatically different cash flow. Always follow up with a full NOI analysis.
  • GRM is best used as a quick first filter to eliminate obviously overpriced listings before you invest time in detailed underwriting.
