Understanding how to use comparable sales, or "comps," is essential for making informed decisions in a real estate transaction. By analyzing recent sales of similar homes in the same area, buyers can determine a fair offer price, while sellers can set a competitive listing price. The most effective comps are homes sold within the past three months, located in the same neighborhood, and sharing key features like square footage and the number of bedrooms and bathrooms. Relying on a knowledgeable local real estate agent is the best way to navigate the nuances of comp analysis and avoid overpaying or underpricing your home.
Comparable sales (comps) are recently sold properties that are similar to a subject property in location, size, condition, and features. For both buyers and sellers, comps provide the most accurate snapshot of a local market’s current value. Buyers use them to justify an offer price, ensuring they do not overpay. Sellers use comps to price their home competitively to attract offers without leaving money on the table. Because the real estate market is dynamic, comps based on data from the last 90 days offer the most reliable indicator of what a property is worth today.
Selecting the right comps involves three critical filters: location, timeframe, and physical characteristics.
Location is the Highest Priority: The ideal comps are within the same neighborhood or subdivision as the subject property. Proximity is key because value is heavily influenced by school district boundaries, access to amenities, and overall desirability. If there are insufficient sales in the immediate area, expanding the search is necessary, but you should always stay within the same school district and avoid crossing major geographical or infrastructural boundaries, like a highway, that can significantly impact value.
Timeframe Matters Significantly: The most relevant comps are from sales closed within the past three months. Data older than six months is often too stale to reflect current market trends. The best indicator of live market conditions is a pending sale—a home under contract but not yet closed. A skilled local agent can often ascertain the pending sale price through professional networks, providing the most up-to-the-minute data point.
Factor in Key Home Features: Beyond price per square foot, it's crucial to compare specific features. Look for homes with a similar number of bedrooms and bathrooms, equivalent square footage, and comparable lot size. Also, consider the condition of major systems (like HVAC and roof), the presence of upgrades (like a renovated kitchen or finished basement), and unique attributes (such as a view or a swimming pool). A simple price-per-square-foot calculation does not account for these value-adds.
No two properties are identical, so adjustments are often necessary. This is where the expertise of a real estate agent becomes invaluable. For example, if a comp sold for $400,000 but has a brand-new roof while your subject property has an older roof, a downward adjustment in value for your home may be appropriate. Similarly, factors like unfavorable proximity to noise (e.g., near a fire station) or a lack of privacy (e.g., backing onto a commercial parking lot) can negatively affect a property's value compared to a comp without these issues. An experienced agent can shed light on these nuances that are not always apparent in online listings.
Many online platforms offer automated valuation models (AVMs). While these can be a helpful starting point, they often lack the nuance of a hands-on comparative market analysis (CMA) conducted by a real estate professional. AVMs may not account for recent upgrades, unique property quirks, or hyperlocal market shifts. For the most accurate pricing, an analysis from a local expert is recommended.
A local real estate agent does more than just pull data from the Multiple Listing Service (MLS). They provide context. They may have personally toured the comparable homes and can explain why one sold for more than another. This local insight prevents you from overanalyzing the comps and getting bogged down in details that an algorithm might miss. Their assessment helps you focus on the big picture and make a confident, data-driven decision.
To effectively use comps, focus on recent sales of similar homes in the immediate neighborhood and trust the nuanced analysis of a local real estate professional to guide your pricing strategy.
