Why Sold Comps Actually Matter More Than Listing Prices
Most people I talk to think they need to track what homes are listed for. That is the wrong data. What you actually need is what homes sold for, because list prices are fantasy. Sellers inflate them. Buyers bid them up. The final number is where reality lives. I spent six months going through MLS reports for a client in Columbus who kept overpaying by $40,000 or so. He was basing offers on active listings that had already been stale for 90 days. We switched to only looking at closed sales from the last 60 to 90 days, and his offer accuracy improved dramatically. He stopped writing three bids and got the fourth one accepted at fair market.Unlock The Secrets Of Recently Sold Homes Near Me A Guide To Homebuying Success
The practical side of this is simpler than most people make it. You pull recent comparable sales, adjust for differences, and you get a ballpark number that is close enough to make an informed offer. Start by filtering for properties sold in the last 90 days within a half-mile radius, or in the same neighborhood if your area does not use strict boundaries. I prefer neighborhood because street-level comps in subdivisions can vary wildly even half a mile apart due to lot size and school zones. Pull at least five to eight comps. Fewer than that and you are guessing. More than fifteen and you are drowning in noise. The sweet spot is usually eight to twelve.
Adjustment Logic That Actually Works
Adjustments are where beginners lose money. Here is how I do it without getting bogged down in spreadsheets: Square footage: In most suburban markets, the adjustment runs about $80 to $150 per square foot depending on location. If your target home is 200 square feet smaller than the comp, subtract roughly $16,000 to $30,000 from the comp price. That is not exact, but it is close enough for an offer strategy. Bathrooms: A full bath adjustment in my experience ranges from $8,000 to $18,000. Half baths are worth less, usually $4,000 to $8,000. These numbers shift depending on whether the market is buyer or seller driven.
Garage: One-car garage differences tend to move the needle by $10,000 to $15,000. Two-car versus three-car is usually only $5,000 to $10,000 because most buyers in many markets do not have more than two vehicles. Condition: This is the hardest one to quantify. A renovated kitchen adds value, but not always the full cost of the renovation. I typically adjust $20,000 to $40,000 for a major kitchen update in mid-range markets, and less in lower-priced areas. In luxury markets, the adjustments are wider because buyers expect finish quality.

Where to Find the Data
If you have access to an agent's MLS portal, that is the cleanest source. Closed sale data appears within a few days of recording. Without an agent, you can use public records, but those lag by 30 to 60 days sometimes. That lag matters in fast-moving markets where prices shift month to month. Redfin and Zillow show sold data, but they have known issues with incomplete fields and occasional price errors. I have seen Zillow list a comp as selling for $325,000 when the county recorded it at $307,500. Always verify with the county recorder or the listing agent when the numbers feel off. For a more hands-on approach, I usually pull directly from the county assessor's website. It is free, it is accurate, and it includes lot size, year built, and sale date. The interface is ugly, but the data is solid. It takes about ten minutes to pull a batch of comps this way compared to thirty minutes on aggregator sites that require you to click through multiple pages.
Edge Case: When Recent Sales Are Not Comparable
I ran into this exact problem last spring in a market where inventory was nearly nonexistent. There were no true comparable sales within a half-mile because everything sold in under a week. The most recent closed property was 1.2 miles away, on a different school boundary, and was a flip that had been cosmetically updated but not structurally. The workaround was to expand the radius to two miles, include pending sales where the contract price was visible, and cross-reference with auction results from the prior quarter to establish a floor value. I also pulled tax assessment trends to see if the area was appreciating faster than the sale data reflected. That combination got me within about 3 percent of what the house eventually sold for after a bidding war.
Common Pitfalls
The biggest mistake I see is using new construction as a comp for existing homes. New construction carries a premium that does not translate to resale value for older homes. If you must use a new build comp, subtract $25,000 to $50,000 depending on the market tier. That covers the land premium and builder margin that a resale buyer would not receive. Another trap is ignoring the sale type. Foreclosures and short sales distort averages. Exclude them unless you are analyzing a distressed property specifically. A foreclosure sold for $180,000 in a neighborhood where everything else goes for $240,000 will drag your median down and make you undervalue a normal purchase. Likewise, family transfers and non-arm's-length sales show up in public records without a flag sometimes. If a comp looks suspiciously cheap or expensive compared to its neighbors, check whether it was a transfer between relatives. Those sales should be discarded from your analysis.
Building Your Price Range
Once you have your adjusted comps, take the median of the adjusted prices, not the average. Averages skew when you have one outlier comp. The median gives you the center point. Then apply a buffer based on current market conditions. In a balanced market, list at or near the median adjusted value. In a seller's market, bid 3 to 5 percent above. In a buyer's market, you can go 2 to 4 percent below, but do not get greedy. Even in a soft market, sellers rarely accept offers that look insulting. I keep a simple running log in a spreadsheet. Columns for address, sale price, square footage, beds, baths, garage spaces, condition notes, and my adjusted value. It takes about 15 minutes to set up per search. The time you save by having a clear number is worth the initial effort.
When to Bring in a Professional
Do it yourself if you are comfortable with spreadsheets and you have time to verify data points. If you are working with a tight timeline or a complicated property, an appraiser or experienced agent can tighten your range to within 1 to 2 percent. The cost is usually $300 to $600 for a desktop appraisal, which is cheap compared to overpaying by $20,000 or more on a home. Bottom line: sold data tells you what buyers actually paid, not what sellers hoped they would get. Focus on that number, adjust carefully, verify the source, and do not chase stale listings as if they represent current value.
