How Do I Find Comparable Sales (Comps) for My Arizona Home?

Short Answer

Comparable sales (comps) are recent sales of similar homes near your property that help estimate market value. To find comps, look for recently sold homes with similar size, location, age, condition, and features, then compare them to your home. Public records, real estate websites, and professional valuations are common sources. There is no universal radius, date range, or adjustment formula—the right comps depend on your property and neighborhood.

What Comparable Sales Are

Comparable sales—often called "comps"—are closed sales of properties similar to yours that are used to estimate what your home may be worth in the current market. Appraisers, agents, and buyers all use comps to judge whether a price is reasonable.

What Makes a Good Comp

A strong comp is as similar to your home as possible:

• Location: Nearby, ideally in the same neighborhood or subdivision.
• Property type: Single-family, townhome, or other—match the type.
• Size: Similar square footage and lot size.
• Bedrooms and bathrooms: Similar count.
• Age and condition: Similar era and condition.
• Features: Pool, garage, solar, upgrades—similar features affect value.
• Sale timing: Recent sales are more relevant than older ones.

There is no universal radius or date range. In a dense subdivision, comps within a few streets and a few months may work. In a rural or custom-home area, you may need to look farther and accept older sales.

Where to Find Comps

• Real estate websites: Consumer portals show recent sales, though data may be incomplete or delayed.
• Public records: County recorder and assessor records show sale prices and property characteristics, though data can be limited or delayed.
• Professional comparative market analysis (CMA): A real estate professional can provide a CMA based on MLS data.
• Professional appraisal: A licensed appraiser provides a formal valuation.

Adjusting for Differences

No comp is identical to your home. You adjust for differences—a larger lot, an extra bathroom, a pool, or a remodeled kitchen may add value; deferred maintenance or an outdated interior may reduce it. There is no universal adjustment formula. Professional appraisers use systematic adjustment methods; homeowners should treat their own estimates as approximate.

Closed Sales vs. Active Listings

Closed sales show what buyers actually paid. Active listings show what sellers are asking—not what homes are worth. Use closed sales as your primary guide and active listings to understand current competition.

Arizona-Specific Considerations

Arizona county assessors and recorders maintain public property records. Phoenix-area subdivisions often have many similar homes, which can make finding comps easier, but condition differences between identical floor plans can be significant.

Dwealling's Role

Dwealling helps you organize pricing research and observe how buyers respond to your asking price, which provides real market feedback. Dwealling does not perform appraisals or guarantee a value. Pricing is $199 setup plus $99 per month.

Arizona Context

Arizona county assessors and recorders maintain public property records. Phoenix-area subdivisions often have many similar homes, making comps easier to find, but condition differences between identical floor plans can be significant. There is no universal radius or date range for comps.

Comps are the foundation of pricing, but I remind sellers that no two homes are truly identical. Two houses with the same floor plan can be worth very different amounts depending on condition, upgrades, and how they've been maintained. I encourage sellers to look at closed sales—not active listings—because asking prices don't tell you what buyers actually paid. And I like to watch how buyers respond to the asking price once it's set. That real-world feedback is often more honest than any estimate.
