Details, formula, and sources
GRM (annual and monthly), the gross rent yield, and an implied value from a market GRM - an income-approach screening metric.
GRM_annual = price / gross_annual_rent; GRM_monthly = price / gross_monthly_rent; implied_value = market_GRM * gross_rent; gross_yield% = 1/GRM_annual * 100.
Standard income-approach screening metric per the Appraisal Institute's The Appraisal of Real Estate income approach, by name; USPAP governs the appraiser's value opinion.
Distinct from cap-rate-dscr, which uses NOI, not gross rent. Screening only.
Estimate. AHJ and licensed professional govern.
