How Are Comparable Home Sales Chosen?
The best comparable sale is not automatically the closest house, the newest sale or the home with the most similar square footage. It is a property that helps explain what the same buyer may pay for your home.
A comparable is a buyer alternative, not just a nearby address
Buyers do not purchase your home in isolation. They compare it with other properties that meet a similar need and fit a similar budget.
A sale one street away may be useful. But another property farther away may be more meaningful if it has the same property type, similar condition, a comparable lot and the same buyer appeal.
What makes one sale more comparable than another?
Market area and buyer alternatives
Subdivision, street position, school assignment, waterfront relationship, golf-course position, noise, access and nearby alternatives can affect whether two homes compete.
Type, size and function
Detached homes, townhomes and condominiums serve different buyers. Living area matters, but layout, bedroom count, parking and usable space can matter just as much.
Renovation and major systems
A remodeled home with a newer roof and systems may not compete evenly with a similar-sized home that needs significant work. Compare what was actually improved, not the word “updated.”
Lot and property influences
Lot size, privacy, view, frontage, flood considerations, outdoor improvements and adverse influences can change buyer appeal.
Sale date and market conditions
Recent sales are helpful when the market has changed. An older sale may still deserve weight when it is more similar or when few relevant homes have sold.
What the sale price included
Seller concessions, unusual financing, personal property or a non-typical transaction may affect what the recorded sale price tells us.
Closed, active, pending and failed listings answer different questions
How a useful comparison is built
Verify the subject property
Confirm the property type, legal and physical facts, living area, lot, age, condition, improvements, major systems and anything else that may affect buyer choice.
Define the likely buyer and market area
Identify the properties a realistic buyer would consider, including alternatives beyond one subdivision when the market supports it.
Search broadly, then narrow carefully
Begin with enough candidates to avoid forcing the answer. Give greater weight to properties that are most similar and explain why others were excluded.
Account for meaningful differences
Do not assume every difference creates a dollar-for-dollar adjustment. Look for market evidence showing how buyers reacted to the feature when reliable evidence exists.
Compare the conclusion with current competition
Ask whether the proposed position makes sense beside the homes buyers can purchase now.
State the uncertainty
Explain where the evidence is strong, where it is weak and what new sale, listing, property fact or buyer response could change the recommendation.
Why simple rules can produce the wrong comparison
“Use the closest three sales.” Distance matters, but buyer competition and property similarity may matter more.
“Only use the last 90 days.” A busy market may provide enough recent evidence. A unique home or low-volume neighborhood may require a longer lookback.
“Multiply square footage by the neighborhood price per square foot.” Price per square foot blends many differences into one number. It can be a check, but it is not a complete valuation method.
“Use every sale in the subdivision.” A nearby sale may have a different property type, lot, view, condition, size or buyer appeal.
“The highest sale proves my value.” It proves one buyer paid that amount for that property under those terms. The question is how closely that sale explains your home.
A broker’s market analysis is not an appraisal
Comparative Market Analysis
A Florida real estate broker may prepare a CMA or broker opinion of value in the ordinary course of business. It helps a seller understand market position and choose a listing strategy.
Appraisal
An appraisal is performed by a qualified appraiser for a defined purpose, often lending. The appraiser independently selects and analyzes the evidence under the applicable assignment requirements.
Questions to ask about the comparable sales
- Which buyers would realistically compare these homes with mine?
- Why was each sale included?
- Which nearby or recent sales were excluded, and why?
- How do condition, improvements and major systems differ?
- What can buyers purchase instead of my home today?
- Which assumptions are supported by market evidence?
- Where is the evidence weak?
- What new information would change the recommended price?
You do not need to agree with every judgment. You should be able to see how the conclusion was built.

Questions homeowners ask
How many comparable sales should be used?
There is no single number that makes every CMA reliable. The analysis should include enough relevant evidence to explain the conclusion without filling the comparison with weak matches merely to increase the count.
Must comparable sales be in the same neighborhood?
No. Same-neighborhood sales can be highly useful when they compete for the same buyer. A broader search may be needed when the home is unusual, few relevant properties have sold or buyers commonly compare other nearby areas.
How recent should comparable sales be?
More recent sales can better reflect current conditions, but similarity also matters. An older sale may be useful when it is a stronger property match. Any meaningful market change between the sale date and today should be considered.
Do active listings count as comparable sales?
They are not closed sales and do not prove value. They show the asking prices, condition and choices competing for today’s buyers.
Should foreclosures or distressed sales be excluded?
Not automatically. First determine whether the transaction competed in the same market and whether its condition, terms or distress made it meaningfully different.
Can renovations be added to value dollar for dollar?
Not automatically. Cost and market value are different. The useful question is how buyers reacted to similar improvements in competing properties.
Is price per square foot a reliable way to value my home?
It is a useful comparison check, but not a complete method. It does not fully explain differences in lot, layout, condition, quality, location, systems or buyer appeal.
Is a CMA the same as an appraisal?
No. A CMA is a broker’s market analysis. It must not be represented as an appraisal. A lender’s appraiser independently completes the appraisal assignment.
Current standards behind this explanation
Fannie Mae UAD 3.6 Policy explains that comparable properties should compete for the same market participants and be similar in physical and legal characteristics.
Freddie Mac Guide Section 5605.6 addresses market-area analysis and comparable selection.
Chapter 475, Florida Statutes distinguishes a broker’s comparative market analysis or price opinion from an appraisal.
