If you're buying or selling a home in Naperville, the appraisal is one of the most pivotal steps between an accepted offer and a closed transaction. It's also one of the most misunderstood. Knowing what happens during a home appraisal — and how to prepare for it — takes a significant amount of uncertainty out of the process and keeps your transaction on track.
Key Takeaways
- A home appraisal is an independent assessment of a property's market value, required by most lenders before they'll approve a mortgage
- Appraisers evaluate the home's condition, size, features, and location alongside recent comparable sales in the surrounding area
- Sellers can prepare for an appraisal by completing visible repairs, documenting improvements, and ensuring the home is clean and accessible
- When an appraisal comes in below the contract price, buyers and sellers have several options — and the deal doesn't have to fall apart
What a Home Appraisal Actually Is
A home appraisal is a licensed, independent appraiser's professional opinion of a property's current market value. Lenders require it to confirm that the home is worth the amount they're being asked to finance — protecting both the buyer and the institution from overpaying for an asset.
Key Facts About the Appraisal Process
- The appraisal is ordered by the lender but paid for by the buyer, typically as part of closing costs, and usually runs between $300 and $600, depending on the property
- The appraiser is assigned independently — neither the buyer's agent nor the seller's agent selects them, which is intentional to ensure an unbiased valuation
- Appraisals are distinct from home inspections — an inspection evaluates condition and identifies issues, while an appraisal determines value
- Most appraisals are completed within a week of the on-site visit, with the full report delivered to the lender shortly after
Understanding the purpose and structure of an appraisal takes the mystery out of what can otherwise feel like an opaque step in the transaction.
What the Appraiser Is Looking At
During the on-site visit, which typically lasts between 30 minutes and a few hours depending on the property's size, the appraiser is gathering specific information to build a defensible valuation.
What Gets Evaluated During the Visit
- The appraiser measures the home's gross living area, verifies the number of bedrooms and bathrooms, and notes the condition of major systems including the roof, HVAC, plumbing, and electrical
- Finishes and features matter — updated kitchens, renovated bathrooms, hardwood floors, and additional structures like finished basements or detached garages all contribute to the final value
- Location factors, including proximity to good schools, major roads, commercial areas, and neighborhood condition are weighed as part of the overall assessment
- The appraiser photographs the interior and exterior extensively, documenting the condition of the home at the time of the visit as part of the official record
After the visit, the appraiser identifies comparable sales — typically three to five recent transactions in the area — and adjusts the home's value up or down based on how it compares.
How Sellers Should Prepare
A home appraisal isn't something you can control entirely, but sellers who prepare thoughtfully tend to get better outcomes. The goal is to make sure the appraiser has every reason to recognize the full value of the property.
Steps Sellers Can Take Before the Appraiser Arrives
- Complete any visible repairs before the visit — peeling paint, broken fixtures, damaged flooring, and missing hardware are the kinds of details that can negatively affect condition ratings
- Prepare a list of improvements made during your ownership, including the approximate cost and year of completion, and have it ready to share with the appraiser at the visit
- Ensure all areas of the home are clean, accessible, and well-lit — appraisers need to access every room, the attic, the basement, and any outbuildings on the property
- If you're aware of comparable sales in the neighborhood that support your home's value, it's appropriate to provide that information — appraisers aren't obligated to use it, but they can consider it
A well-prepared seller signals that the home has been well-maintained, which supports a stronger valuation.
What Happens When the Appraisal Comes In Low
A low appraisal doesn't automatically end a transaction, but it does require a decision. When the appraised value comes in below the contract price, the gap between the two numbers needs to be resolved before the lender will approve the loan.
Options When the Appraisal Falls Short
- The buyer can make up the difference in cash by paying the gap between the appraised value and the contract price out of pocket, which is common in competitive markets where buyers are highly motivated
- The seller can agree to reduce the sale price to the appraised value, eliminating the gap and allowing the transaction to move forward on its current terms
- Both parties can negotiate a middle-ground solution — the seller reduces the price partially and the buyer covers the remaining gap — splitting the difference and preserving the deal
- The buyer can formally dispute the appraisal by submitting a rebuttal of value with documented comparable sales, which the lender will review and may send back to the appraiser for reconsideration
Low appraisals are more common in fast-moving markets where sale prices are outpacing recorded comparable data — and with the right guidance, most transactions survive them.
FAQs: What Happens During a Home Appraisal
Can a seller be present during the appraisal?
Yes, and in most cases it's a good idea. Being present gives you the opportunity to point out improvements, answer questions about the property, and provide any documentation you've prepared in advance.
How long does an appraisal take from start to finish?
The on-site visit typically takes 30 minutes to a few hours. The full written report is usually delivered to the lender within a week of the visit, though timelines can vary based on appraiser workload and market conditions.
What if I disagree with the appraised value?
Buyers have the right to request a reconsideration of value through their lender. To be successful, the request should include specific comparable sales that support a higher valuation — vague disagreement without data rarely moves an appraiser's conclusion.
