Estimate Market Value — Three Practical Approaches

This tool lets you estimate residential or small rental property value with: Income (Cap-Rate), Sales Comps (Price/ft²), and a quick GRM check. It’s educational—use local market data where possible and confirm with a professional appraisal before transacting.

Inputs

Operating expenses exclude debt service & major capital projects; CapEx reserve is modeled separately.

Income approach: estimate NOI (effective income − operating expenses − reserves) then divide by cap rate for value. NOI excludes loan payments.

Sales comps: derive a price/ft² from recent comparable sales, trim outliers, and multiply by subject size.

GRM: quick gross-rent check; less precise because it ignores expenses and vacancies.
