GRM vs. Cap Rate

I genuinely believe that GRM is the "smoke detector" of real estate investing. If the GRM is unusually high (e.g., 20+), you don't even need to look at the expenses to know the deal is likely overpriced. It tells you exactly how many years of gross rent it would take to pay for the property.

The Formula: GRM = Property Price / Gross Annual Rent. A lower GRM is generally better for the buyer, while a higher GRM is better for the seller.

Why use GRM?

  • Speed: You can calculate it in seconds using only two numbers from a listing.
  • Neighborhood Benchmarking: Compare similar properties in the same zip code to see which one is the best value.
  • Simplicity: It ignores complex operating expenses, making it perfect for initial screening.
