Frequently asked questions about appraisals
These are the questions clients, agents, and attorneys actually ask working appraisers, answered plainly. Where we have a full article on a topic, the answer here is short and the article carries the detail.
Who does the appraiser actually work for?
Neither side. The appraiser’s role has always been the independent third party between two people who disagree about what something is worth, because the seller always thinks it is worth more and the buyer always thinks it is worth less. In a lender-ordered appraisal, the lender is the client, but federal appraiser independence requirements, established under the Dodd-Frank Act and its Appraiser Independence Requirements (AIR), exist precisely so that no one, lender included, can pressure the number. The value opinion is the appraiser’s alone.
Will AI or an algorithm replace the appraiser?
Appraisers get this question constantly, and the working answer from inside the profession is no. Automated models are structurally blind to condition: they assume average condition on every property because there is no scalable way to see a roof, a foundation, or a renovation from a data feed. Technology changes how appraisers work. It does not replace the judgment.
How accurate is a Zestimate compared to an appraisal?
Automated estimates are a starting point, not a value conclusion, and the miss rates cut in both directions. We cover the comparison in detail in our article on Zestimates versus appraisals. Zestimate vs Appraisal: Which One Tells the Truth About Your Home’s Value?
What happens if the appraisal comes in below the contract price?
First, understand what the number is: an opinion of market value supported by evidence, not a verdict on your deal. A quality report should be able to explain why it makes sense that value came in below contract. From there the parties have options: renegotiate, bring more cash, or examine whether the report has actual deficiencies worth challenging. On that last piece, see our article on what happens when an appraisal gets challenged. If Your Appraisal Gets Challenged, Does It Hold Its Ground?
Can I challenge an appraisal I think is wrong?
Yes. The formal mechanism in lending contexts is a reconsideration of value, and it works when it is built on evidence, specifically comparable sales the appraiser may have missed, rather than on disappointment with the number. Agents invoke it often, and often incorrectly. The mechanics are covered in our challenged-appraisal article. If Your Appraisal Gets Challenged, Does It Hold Its Ground?
Is it true an appraiser can only use sales from the last 90 days?
No. This is one of the most persistent myths in real estate, usually passed from agent to agent with no source behind it. Appraisers can and do go back further than 90 days when the market evidence calls for it.
Is it true comps have to come from within half a mile?
Also a myth, from the same family. There is no fixed radius. The search area follows the market the property actually competes in, which can be a few blocks in a dense city neighborhood or many miles in a rural one.
How much value does a specific feature add, like a fireplace or a third garage bay?
There is no fixed dollar figure, and any appraiser quoting one without studying your market segment is guessing. A fireplace contributes differently on a million-dollar home than on a modest one, and the same is true of nearly every feature. The adjustment comes from what buyers in that price tier actually pay, not from a table.
Will my renovation add what it cost?
Cost and value are different things. Some improvements return their cost in market value, many return only part of it, and a few return nothing because buyers in the segment do not pay for them. An appraisal measures contribution to market value, not your receipts.
Is the appraiser inspecting my house like a home inspector?
No. A home inspector evaluates condition and defects for a buyer, and it is a separately licensed role. An appraiser observes the property to value it: quality, condition as it bears on value, layout, and the features that define which market the home competes in. The appraiser is not producing a defect report, and a clean appraisal is not a clean bill of health.
Can I walk the appraiser through the property and point things out?
Yes, and it helps. Homeowners are often eager to show what they love about the property, and useful facts surface that way: updates, mechanical ages, permits, what the neighbors’ houses sold for. Point out what is not visible. The appraiser weighs it against the market evidence.
What is a date-of-death or retrospective appraisal?
An appraisal with an effective date in the past, most commonly the date of a property owner’s death, used for estate settlement and tax purposes. Retrospective assignments are an established and growing category of non-lender work, and they require historical market data rather than today’s.
How does a divorce appraisal work when both spouses need the number?
Often as a joint appraisal, where both parties are the client and the appraiser is a neutral rather than each side hiring a dueling expert. It is faster, cheaper, and less adversarial, and the appraiser’s job is to stay entirely outside the emotional crossfire.

Can an appraisal help me appeal my property taxes?
Yes. An independent appraisal is evidence an assessment appeals board can weigh against the assessor’s value, and appraisers regularly prevail in these hearings when the market evidence supports them.

Will the appraiser testify if my case goes to a hearing?
Appraisers who take litigation and tax appeal work do testify, and experienced ones treat it as part of the assignment: stay calm, answer to the decision-maker, and let the evidence carry the argument. If your matter may end up in front of a judge or board, say so at engagement, because it changes the scope and the report.
What is an appraisal waiver?
A lender decision, driven by the loan’s risk profile, to accept a value without a full appraisal. It means the lender did not require one, not that the property’s value is settled. What that means for you as a borrower is covered in our appraisal waiver article. Appraisal Waivers: Benefits and Risks in 2026
Why does an appraisal cost what it costs?
You are paying for a licensed professional’s market analysis, inspection, and a report that holds up in front of whoever relies on it. Measured against what is at stake, and against what the fee was decades ago relative to home prices, practitioners make a fair case that appraisals are one of the cheaper professional services in a transaction.
How long will my appraisal take?
It varies with complexity and with market volume. Turnaround stretches when demand is at capacity and tightens when it is not, and an unusual property takes longer than a conforming one because the evidence takes longer to find. Ask for the timeline at engagement; a firm quote beats a hopeful one.
What kinds of situations need an appraisal besides buying or selling?
More than most people expect: estate settlement, divorce, tax appeal, insurance questions, probate, gifting and planning, partnership dissolutions, and general market-value questions when a decision needs a real number. If a document, a court, or a decision depends on what property is worth, that is appraisal work.
