A screen, not a valuation

GRM ignores operating costs entirely, so it compares two properties fairly only when their expense profiles match. A building with tenant-paid utilities and one with landlord-paid heating can show the same GRM and produce very different net income. Use it to shortlist, then move to cap rate and cash flow.

The formula

GRM = purchase price ÷ annual gross rent

Every result on this page comes from this formula. Nothing is rounded until the final display, so figures match a spreadsheet to the cent.
