Valuation & Appraisal

    Gross Rent Multiplier (GRM)

    A quick valuation tool equal to sale price divided by gross rent, using gross income rather than net.

    The gross rent multiplier is a fast way to compare income properties. It equals the sale price divided by the gross rental income. Because it uses gross rent, it does not account for vacancy or operating expenses.

    GRM is a screening tool, not a precise value. Appraisers use it for quick comparison and rely on the full income approach for a supported value.

    On the exam

    GRM uses gross rent. The cap rate uses net operating income. The exam tests that you do not mix the two.

    Worked example

    A 480,000 dollar price divided by 57,600 dollars of gross annual rent equals a GRM of 8.33.

    Exam trap

    Do not use net income in the GRM. It is built on gross rent.
