It happens all the time. A house sells three doors down and now everyone in the neighborhood knows what their home is worth.
And this time, it isn’t just a similar house. It’s a model match.
Many subdivisions were originally built with a relatively small collection of floor plans. Maybe the builder offered three models, perhaps four or five, and repeated them throughout the neighborhood. So the house three doors down isn’t merely about the same size as yours. It’s essentially the same house.
Same builder. Same floor plan. Built around the same time. Both are about 2,100 square feet, with three bedrooms, two-and-a-half bathrooms and a three-car garage. If the house three doors down just sold for $825,000, yours must be worth about $825,000 too, right?
Maybe.
In fact, that sale may be one of the best pieces of market evidence available for understanding the value of your home. Appraisers spend a lot of time looking for exactly that kind of comparable property.
But comparable doesn’t mean identical. Even model matches can have spent the last twenty or thirty years becoming very different houses.
One owner replaced the original windows years ago. Another remodeled the kitchen and bathrooms. One has the original roof. One added a pool. One backs to open space while the other backs to a busy road. One has been comprehensively updated while another has been improved a little at a time, with finishes from several different decades.
Years ago, some of those differences could be relatively easy to recognize in the market. One house had dual-pane windows and another didn’t, and buyers might demonstrate a fairly identifiable preference. Today’s buyer reactions can be more complicated. Financing, changing expectations and years of increasingly sophisticated home improvements have helped create buyers who often react to the overall package rather than one feature at a time.
A remodeled kitchen matters, but perhaps not as much when the bathrooms, flooring, windows and roof still need attention. Conversely, a house where nearly everything has already been thoughtfully updated may receive a market reaction that is difficult to attribute to any single improvement.
That’s where two houses that appear nearly identical on paper can begin producing very different results.
The Things You Can’t See on a Spreadsheet
Imagine those same two houses built from the same floor plan in the same subdivision.
One sits inside the neighborhood on a quiet street and backs to open space. The other sits near the entrance to the subdivision and backs to a busy road. The county records may describe them almost identically. Same general size, same age, same bedroom and bathroom count.
Stand in their backyards and they may not feel similar at all.
Now walk inside. One still has its original kitchen, flooring and bathrooms from 1998. Everything works and the owners have taken good care of it. The other has a remodeled kitchen, updated bathrooms, newer flooring and windows and an outdoor living area that connects naturally with the house.
That doesn’t automatically tell us how much more one is worth. It doesn’t mean we total the remodeling receipts and add them to the sale price of the other house. It means buyers are being presented with two different properties.
The question for an appraiser isn’t simply whether those differences exist. The question is whether the market recognizes them and, if so, how.
Buyers Don’t Shop From Property Records
Property data are enormously useful. We use public records, MLS information, maps, prior sales, permits when available and a whole collection of information to understand a property and its market. But buyers don’t purchase a row in a database. They respond personally to what they see and how a home feels. Homes are personal, often emotionally so.
They stand in the kitchen. They look out the windows. They notice whether the backyard feels private. They see the condition of the flooring. They notice the traffic noise. They decide whether the floor plan works for their family. They see a recently remodeled bathroom or a bathroom they immediately begin mentally budgeting to replace.
Sometimes they react to things that are difficult to reduce to a single number. A view. Privacy. Natural light. An unusually useful backyard. A steep driveway. A great workshop. An awkward addition. A pool. Too much pool. Not enough parking. An updated chef’s kitchen in a house where everything else still needs work.
Individually, some of these differences may contribute very little. Others can materially affect how buyers respond to a property.
That’s one reason an appraiser can’t simply find the closest house with the same square footage and call the problem solved.
Comparable Doesn’t Mean “The Same”
The word comparable probably creates some confusion by itself.
When appraisers talk about comparable sales, we’re not saying we found houses identical to the one we’re appraising. Most of the time, no such properties exist. We’re looking for sales that help us understand how buyers behave in the subject property’s market.
Sometimes the best comparable really is three doors down.
Other times the house three doors down is less useful than one half a mile away because the second sale is more similar in condition, lot utility, view, quality, design or some other characteristic buyers appear to care about. Then we have to analyze the differences.
If buyers consistently pay more for homes with a particular feature, that tells us something. If a feature costs homeowners $75,000 to install but buyers don’t appear to pay anywhere near $75,000 more for homes that have it, that tells us something too.
This is where appraisal becomes less about finding a house that looks similar and more about understanding what the market is saying.
Even “Value” Needs a Little Explanation
There’s another wrinkle worth mentioning because we use the word value as though every property has one number permanently attached to it. It doesn’t.
An appraiser first has to understand the valuation question being asked. For this conversation, we’re talking about the kind of value most homeowners generally have in mind when they point to the neighbor’s sale: What does the market indicate for my property?
But appraisers can be asked very different questions.
An estate appraisal completed today may ask what a property was worth when someone passed away several years ago. That’s a retrospective valuation, and the appraiser is looking backward to a different market and effective date.
An insurance assignment may be concerned with what it would cost to reconstruct the improvements, which isn’t the same thing as what a buyer would pay for the entire property.
An income-producing property may require us to consider how buyers react to the income the property can generate.
There are also distinctions involving replacement cost, reproduction cost, depreciation and different definitions of value depending upon the assignment and its intended use.
Same property. Different questions. Potentially different answers.
That’s a much larger conversation for another day, but it’s important here because before we start comparing two houses, we need to know what question we’re trying to answer. For now, let’s stay with what buyers are doing in the market.
What About the $100,000 Kitchen?
This is where homeowners sometimes understandably get frustrated.
Suppose you’ve spent $100,000 remodeling your kitchen. The house down the street still has the original cabinets and tile counters. Surely your house is worth $100,000 more.
Maybe it is.
But spending $100,000 and creating $100,000 in market value are two different things.
You purchased materials, labor, appliances and, hopefully, years of enjoyment from a kitchen designed the way you wanted it. The market isn’t required to reimburse you dollar for dollar for those decisions when you sell.
Buyers may absolutely prefer your remodeled home. They may pay more for it. The question is how much more the market supports, not simply how much you spent.
The same thing happens with pools, solar systems, workshops, landscaping, additions and dozens of other improvements.
Cost is a fact. What that cost contributes to market value is a different question.
Sometimes the Less Obvious Difference Matters More
Now imagine those same two neighborhood houses again. Your home has the nicer kitchen. The neighbor’s house has the better lot.
Which matters more?
That’s where things get interesting.
There isn’t a universal adjustment sheet that says remodeled kitchen equals X, open-space view equals Y, pool equals Z and three-car garage equals another fixed amount. Markets behave differently from neighborhood to neighborhood and over time.
A pool in one market may be highly desirable. Somewhere else it may narrow the buyer pool.
A large acreage parcel may command a significant premium in one area. In another, additional acreage may contribute surprisingly little because it’s steep, inaccessible, difficult to use or simply not valued by buyers in that market.
A long-range view may matter enormously. An extra bedroom may matter less than an owner expects.
The appraiser’s job is to look for evidence of how the market is responding to those differences rather than simply assigning them values because they exist. And sometimes the evidence tells us something homeowners don’t expect.
Your Neighbor’s Sale Still Matters
None of this means you should ignore the house that sold three doors down. Quite the opposite.
If it’s similar to yours, in the same neighborhood, sold recently under normal market conditions and appeals to the same general buyers, it may be excellent evidence. It just isn’t necessarily the whole answer.
Your house may be worth more. It may be worth less. It may be worth remarkably close to exactly what the neighbor’s house sold for.
The point isn’t that homeowners are wrong for comparing their houses to nearby sales. That’s essentially where market analysis begins. The mistake is assuming that’s where it ends.
Two houses can share a builder, floor plan, age, square footage and neighborhood and still offer buyers noticeably different experiences. The market gets to react to those differences.
Our job is to figure out whether it did.
So the next time the house three doors down sells and someone says, “Well, now we know what ours is worth,” they may actually have learned something very useful.
They’ve found a good place to start.
They just haven’t necessarily reached the answer yet.
