Lenders require appraisals to protect their investment — but buyers benefit from understanding them too. Here's how the process works.

Key Takeaways

  • Lenders order appraisals to protect themselves, but the results directly affect what buyers can borrow.
  • If the appraised value comes in below the purchase price, buyers may need to renegotiate or cover the gap in cash.
  • Appraisers evaluate location, condition, size, and recent comparable sales — not just the listing price.
  • Buyers typically pay the appraisal fee at closing or upfront, usually between $300 and $600.
  • A low appraisal doesn't automatically kill a deal — several options exist to keep the transaction moving.
  • An appraisal is not a home inspection; it assesses value, not the full condition of the property.

Why Lenders Require an Appraisal

When a lender agrees to finance a home purchase, the property itself serves as collateral for the loan. If a buyer defaults, the lender needs to be confident it can recover its money by selling the home. That's the core reason every conventional and government-backed mortgage requires an appraisal: the lender won't lend more than a home is actually worth.

For buyers, this creates an important dynamic. You may agree to pay $450,000 for a home, but if an independent appraiser values it at $420,000, your lender will typically only finance based on the lower figure. The $30,000 gap becomes your problem to solve. Understanding this mechanism before you make an offer is essential — it's a core piece of what first-time buyers need to know before they begin seriously shopping.

Appraisals that come in below the contract price

Industry data from Fannie Mae and appraisal trade groups suggest low appraisals are a consistent occurrence, particularly in rapidly appreciating markets.

What an Appraiser Actually Evaluates

A licensed appraiser conducts both an in-person property visit and a thorough market analysis. During the visit, they assess:

  • Location and neighborhood — proximity to schools, employment centers, and amenities
  • Physical condition — age, structural integrity, finishes, and any visible issues
  • Size and layout — square footage, number of bedrooms and bathrooms, and functional use of space
  • Recent comparable sales — typically 3–5 similar homes that have sold nearby within the past 3–6 months

The appraiser reconciles these factors to arrive at a final opinion of value, which is documented in a formal appraisal report delivered to the lender. Notably, the appraiser's job is to reflect what the market would pay — not to validate a listing price or confirm a buyer's offer.

Help the Appraiser Capture Full Value

Sellers and their agents typically prepare for the appraisal visit, but buyers benefit from knowing what's considered. If you've negotiated repairs or upgrades as part of your purchase agreement, make sure those are documented and visible. While buyers don't control the appointment, your agent can confirm the appraiser has access to the full property and any relevant permits or improvement records.

The Appraisal Timeline in a Typical Transaction

Appraisals are ordered after a purchase agreement is signed, usually as part of the lender's underwriting process. For a complete picture of where this fits in the transaction, see our stage-by-stage overview of the homebuying process.

Once ordered, the appraisal is typically completed within one to two weeks, though timelines can stretch in high-demand markets where appraisers are in short supply. The lender will share the report with the buyer, who has a right to receive a copy under federal law.

Many buyers include an appraisal contingency in their purchase contract, which provides the right to renegotiate or exit the deal without penalty if the appraisal falls short. This contingency is one of several protective clauses covered in detail in our guide to contingencies that protect home buyers.

When the Appraisal Comes In Low: Your Options

A below-contract appraisal is one of the more stressful moments in a home purchase, but it's not necessarily a deal-breaker. Buyers generally have three paths forward:

  1. Negotiate a price reduction — Request that the seller lower the purchase price to match the appraised value. Sellers may agree, especially if they want to close quickly or the market has softened.
  2. Cover the gap out of pocket — Pay the difference between the appraised value and the purchase price in cash, in addition to your down payment. This is more feasible for buyers with significant reserves.
  3. Challenge the appraisal — Submit a reconsideration of value (ROV) to your lender with evidence of comparable sales the appraiser may have missed. This doesn't always succeed, but factual errors or overlooked data can sometimes lead to a revised value.

Your buyer's agent can play a critical role here, helping you identify relevant comps and advising on negotiation strategy based on current market conditions.

Appraisal vs. Assessed Value: Not the Same

A home's tax-assessed value — set by the local government for property tax purposes — is separate from its appraised market value. Assessed values are often lower than market value and are updated on fixed cycles, not in real time. When a lender orders an appraisal, it reflects current market conditions, not what the county tax rolls say.

Frequently Asked Questions

The buyer typically pays the appraisal fee, which usually ranges from $300 to $600 depending on property size and location. The fee is often collected upfront or rolled into closing costs. Even though the buyer pays, the appraisal is ordered by and belongs to the lender.
The on-site visit generally takes 30 minutes to a few hours depending on the property's size and complexity. The appraiser then prepares the written report, which typically takes a few business days to a week. Your lender will notify you once the report is received.
A low appraisal means the lender will only finance up to the appraised value, leaving a gap if the purchase price is higher. Buyers can negotiate a lower price with the seller, pay the difference in cash, or challenge the appraisal with additional comparable sales data. In some cases, the deal may fall through if no agreement is reached.
No — these are two separate processes. An appraisal establishes market value for the lender's benefit. A home inspection examines the property's physical condition, including systems, structure, and potential defects, primarily for the buyer's benefit. Both are important steps in the homebuying process.
Yes. Buyers or their agents can submit a formal reconsideration of value (ROV) request to the lender, providing evidence such as more relevant comparable sales the appraiser may have overlooked. The appraiser is not obligated to change the value, but factual errors or missing data can sometimes result in a revised opinion.
The appraisal report belongs to the lender, and sellers are not automatically entitled to see it. However, in practice, the appraised value often becomes known during negotiations — especially if it comes in below the contract price and the buyer needs to renegotiate.
