Behind the Number: How Appraisers Value Your Home

Posted on October 16, 2025 Written by Connie Dolansky

When you’re getting a property appraisal—whether you’re buying, selling, settling an estate, or just curious about your home’s value—it helps to understand how appraisers determine that number. While every home is unique, licensed appraisers rely on a professional set of tools and techniques to ensure your valuation is fair, unbiased, and based on real data.

There are three primary methods used in residential property appraisals: the sales comparison approach, the cost approach, and the income approach. Depending on the purpose of your appraisal and the type of property you own, the appraiser may use one or more of these methods to arrive at a well-supported conclusion of value.

Sales Comparison Approach

The sales comparison approach is the most common for residential properties. The appraiser researches recent sales of homes in your area that are similar in size, age, condition, and features. These are called comparables or “comps.” Adjustments are then made to reflect differences between your home and the comps.

For example, if a nearby home sold for $450,000, but your home has a newly renovated kitchen or an extra bedroom, the appraiser may adjust your value upward to reflect that. Likewise, if your property has deferred maintenance or fewer amenities, the value could be adjusted downward.

This approach answers a practical question: What would a typical buyer be willing to pay for a home like yours in today’s market?

Cost Approach

The cost approach considers what it would cost to rebuild your home from scratch, using current material and labor prices, then subtracts any depreciation from wear and tear or age. This approach is especially useful for newer homes or properties with unique features where comparable sales are limited. It’s also useful when determining value for insurance purposes or unique situations like recently completed renovations or newly constructed additions.

Think of it this way: If your home were destroyed tomorrow, how much would it cost to rebuild it, and how much has its condition or age diminished its value?

Income Approach

While this method is less common for owner-occupied homes, it’s essential for appraising rental or investment properties. The income approach evaluates what the property is worth based on the income it produces or could reasonably produce.

The appraiser considers current rental income, market rental rates, operating expenses, and expected return on investment to determine the value from an investor’s perspective. This approach is also sometimes used for multi-unit properties or homes with accessory rental units.

It helps answer the question: What would an investor pay for this property based on its income potential?

How This Impacts Your Home’s Valuation

Understanding these approaches can take some of the mystery out of the appraisal process and help you feel more confident in the final report. Whether you’re preparing for a legal settlement, challenging your property tax assessment, planning your estate, or just want to know your home’s current market value, a professional appraisal offers an objective, data-driven perspective. The appraisal is more than a price, it’s understanding what your home is worth in context of the surrounding area, condition, and other factors.

If you’re considering a private appraisal, we’re here to help you get the clarity you need with professionalism, accuracy, and local expertise.
