At some point, almost every homeowner encounters an appraisal. It might be when you’re refinancing your mortgage, trying to tap your home equity through a HELOC, removing PMI, selling your home, or even appealing your property taxes. In every one of those situations, the appraised value of your home determines what happens next — and how much money you walk away with.
Most homeowners have no idea how the process works until they’re in the middle of it. Here’s what you need to know before an appraiser shows up at your door.
What an Appraisal Actually Is
A home appraisal is an independent, professional opinion of your property’s market value. It’s performed by a licensed or certified appraiser who has no financial stake in the outcome. The appraiser works for the lender (even though you pay for it), and their job is to protect the lender from making a loan that exceeds the property’s value.
The appraiser inspects the property, measures the living area, notes the condition and features, and then compares it to recent sales of similar homes in the area. Those comparable sales — called “comps” — are the foundation of the value opinion. The final number isn’t what your home is “worth” in some absolute sense. It’s what the data says a buyer would pay for it in the current market.
How Appraisals Affect Refinancing
When you refinance, the lender orders an appraisal to confirm your home’s current value. Your loan-to-value ratio (LTV) determines whether you qualify and what rate you get.
If the appraisal comes in high, you have more equity, a better LTV, and access to better terms. If it comes in low, your refinance might get denied, your rate might be worse, or you might need to bring cash to closing to make up the difference.
This is especially relevant for cash-out refinances and HELOCs, where the amount you can borrow is directly tied to the appraised value. A $10,000 difference in appraised value can mean a $10,000 difference in what you can access.
How Appraisals Affect Home Sales
In a purchase transaction, the appraisal protects the buyer’s lender. If you’ve agreed to sell your home for $350,000 but the appraisal comes in at $330,000, the lender will only loan based on the lower number. The buyer then has to make up the $20,000 gap with cash, you have to lower the price, or the deal falls apart.
This is why pricing your home correctly from the start matters so much. Overpricing doesn’t just slow down your sale — it creates appraisal problems that can kill deals even after you’ve accepted an offer.
How Appraisals Affect PMI Removal
If you’re paying private mortgage insurance and believe your home has appreciated enough to give you 20% equity, you can request a new appraisal to prove it. If the appraisal supports the higher value and your LTV drops below 80%, your lender must remove PMI.
On a $300,000 loan, PMI typically costs $150-$300 per month. Getting rid of it is an immediate, permanent monthly savings — but only if the appraisal cooperates. Understanding how equity builds helps you know when the timing is right to make this move.
How to Prepare for an Appraisal
You can’t control the comparable sales in your area, but you can control how your home presents. Here’s what actually matters:
Clean and declutter. An appraiser isn’t judging your decorating, but a clean home looks better-maintained, which can influence the condition rating. A condition rating adjustment can move the value by thousands.
Complete minor repairs. Fix leaky faucets, patch holes in walls, replace broken fixtures. These small issues signal deferred maintenance and can result in a lower condition rating.
Document improvements. If you’ve made significant upgrades — new roof, kitchen remodel, HVAC replacement — have the receipts and dates ready. The appraiser may not know about work that was done unless you tell them.
Know your comps. Look at recent sales in your neighborhood on Zillow or Redfin before the appraisal. If you know of a comparable sale that supports a higher value, mention it to the appraiser. They’re not obligated to use it, but good appraisers appreciate useful information.
Ensure access. The appraiser needs to see the entire home, including the attic access, garage, all bedrooms and bathrooms, and the exterior. Locked rooms, aggressive pets, or areas that can’t be accessed create problems.
What If the Appraisal Comes in Low?
A low appraisal isn’t the end of the world. You have options:
Request a reconsideration of value. If you believe the appraiser used poor comparable sales or made factual errors, you (through your lender) can submit additional comps or corrections and ask the appraiser to reconsider. This works more often than people think.
Get a second appraisal. In some cases, you can order a new appraisal from a different appraiser. This is more common with VA loans, which have a specific process for second appraisals.
Negotiate. If you’re selling and the appraisal comes in low, you and the buyer can split the difference, the buyer can bring extra cash, or you can lower the price. Most deals find a middle ground.
The Bottom Line
An appraisal is one of the most consequential events in homeownership, and it’s one of the few you can actually prepare for. Whether you’re refinancing, selling, removing PMI, or appealing your property taxes, the appraised value sets the ceiling on what’s possible. Take it seriously, prepare your home, know your comparable sales, and understand your options if the number isn’t what you hoped for.
