For homeowners and agents
Because the two numbers answer different questions. The price is what one buyer agreed to pay on one day. The appraised value is what the evidence from the wider market supports. Most of the time the gap has a specific, findable cause — and knowing which one you are looking at decides what you can do about it.
A contract price is a single data point: one buyer, one seller, one negotiation, one day. It can be driven by how badly someone wanted the house, how many other offers there were, how tired the buyer was of losing, or a relocation deadline.
An appraised value is a conclusion drawn from what comparable properties actually sold for. It is deliberately not a prediction of what any one person will pay. It is an estimate of what the market, on the evidence available, has been paying for a property like this one.
So “the appraisal came in low” is really the statement the price agreed is above what similar sales support. That can happen for good reasons and bad ones, and the useful work is figuring out which.
The question is never “is the buyer wrong?” It is “what did the market pay for houses like this, and is there a reason this one should sit above that?”
A seller agrees to pay several thousand toward closing costs, and the price is raised to cover it. The recorded sale price goes up; the economic reality does not. Appraisers adjust for this, which is why a house that “sold for” more can support less. If your contract has concessions in it, that is the first place to look.
In a fast market, the top of a bidding war is by definition above what the last several comparable sales showed. That is not a mistake by anyone. It is the market moving, and an appraisal built on sales that closed sixty or ninety days ago will lag it. The honest phrasing is that the price is ahead of the evidence, not that the price is wrong.
An owner spends heavily on a renovation, a pool, a casita, a workshop, solar. Cost and value are different things, and for most improvements the market returns less than was spent — sometimes much less. This is the hardest conversation in the process because the money was really spent. It just was not recovered.
Sometimes the list price was set optimistically, a buyer agreed to it, and there is simply nothing in the neighbourhood that closed at that level. No amount of argument fixes this one.
It happens. An out-of-area appraiser mixes an age-restricted community with a non-restricted one, treats a two-storey sale as comparable to a single-storey, crosses a boundary that matters locally, or misses a superior sale that closed the week before. This is the only cause on this list where a reconsideration of value has a real chance — and it is why the comparables page matters more than the conclusion page.
A reconsideration is not an appeal on the grounds that you disagree. It is a request to look again in light of evidence the appraiser did not have or did not weigh. What moves it:
What does not move it: what the seller paid, what the house is listed for, what a website estimate says, what it cost to renovate, or how much the buyer loves it.
The lender will lend against the appraised value, not the contract price. So the difference has to be resolved by somebody:
None of those are pleasant, which is exactly why the number is worth getting right before a house goes under contract rather than after.
A large share of low appraisals are not surprises to anybody who looked carefully at the comparable sales first. The sales were there. They just were not examined, because the pricing conversation was run on price per square foot, or on a website estimate, or on what the neighbour is asking.
An estimate that shows you which sales it used, and what it added or subtracted for each difference, tells you in advance whether the number you are about to accept is supported. An estimate that shows only a number cannot.
