Appraisal Fundamentals
The Income Approach for Residential Property
A narrower, income-focused method used mainly for 2-4 unit and rental properties — not the typical owner-occupied home.
The Income Approach values a property based on its ability to generate rental income rather than on comparable sales alone. It's the least commonly used of the three approaches in residential work, reserved largely for properties where rental income genuinely drives buyer behavior.
Where This Approach Actually Applies
2-4 Unit Properties
Duplexes, triplexes, and fourplexes are commonly valued in part by their rental income potential, alongside the Sales Comparison Approach.
Single-Family Rentals
When a subject property is tenant-occupied or held as an investment, market rent analysis can support the overall opinion of value.
Gross Rent Multiplier (GRM)
A simplified income technique used in residential work — market sale price divided by market rent — applied cautiously and only when comparable rent and sale data both support it.
How It Interacts With the Other Approaches
Even on an eligible property, the Income Approach is rarely used alone. It's typically developed alongside the Sales Comparison Approach (and sometimes the Cost Approach), and the appraiser reconciles the results into a single supportable opinion — see our guide on reconciliation for how that final step works.
What This Approach Does Not Mean
It doesn't mean a landlord can raise a home's appraised value simply by charging above-market rent — the analysis relies on market rent, not one owner's specific lease. And for a standard owner-occupied home, the absence of an Income Approach isn't a shortcut or a gap; it's simply the appropriate scope of work for that type of property.
