What Happens If a Home Appraisal Comes in Low in Illinois?
Short answer: If a home appraises for less than the agreed purchase price, the lender may not finance the transaction as originally planned. The buyer and seller may renegotiate, the buyer may cover some or all of the difference, the appraisal may be challenged with supporting evidence or the contract may be terminated if it contains an applicable contingency.
A low appraisal does not automatically cancel the transaction or require the seller to lower the price. What happens next depends on the mortgage, the contract and any appraisal-related language negotiated when the offer was written.
WHAT IS A HOME APPRAISAL?
A home appraisal is an independent opinion of the property’s value. Mortgage lenders use appraisals to evaluate whether the property provides adequate security for the requested loan.
The appraiser may consider:
• Recent sales of reasonably comparable properties
• The home’s size, condition, quality and features
• The lot and location
• Finished versus unfinished living space
• Garages, basements, additions and improvements
• Market conditions affecting comparable sales
• Adjustments for meaningful differences between properties
The appraiser is not performing a home inspection. An appraiser evaluates value and certain property characteristics; an inspector conducts a more detailed examination of the home’s physical condition.
The Consumer Financial Protection Bureau explains that an appraisal is an independent assessment and that buyers should review the completed report for accuracy.
WHAT DOES “APPRAISED BELOW THE PURCHASE PRICE” MEAN?
Suppose a buyer agrees to pay $450,000, but the appraisal reports a value of $435,000. That creates a $15,000 difference, commonly called an appraisal gap.
It does not necessarily mean the buyer overpaid or that the seller priced the home incorrectly. An appraisal is one professional’s supported opinion based largely on available market evidence. A buyer may value a property differently because of its location, layout, condition, competition or personal suitability.
The practical problem is financing. The lender will not simply treat the additional $15,000 as though the property had appraised at $450,000. The lender may recalculate the loan using the lower value, potentially increasing the amount of cash the buyer must bring to closing.
WHAT ARE THE BUYER’S OPTIONS?
1. ASK THE SELLER TO REDUCE THE PRICE
The buyer may ask the seller to lower the purchase price to the appraised value.
The seller is not automatically required to agree. The seller may believe the contract price reflects the market, particularly when multiple buyers competed for the home.
2. PAY THE ENTIRE APPRAISAL GAP
If the buyer has sufficient funds, the buyer may pay the difference between the contract price and appraised value.
Using the previous example, the buyer could proceed at $450,000 and contribute the additional funds required by the lender.
This money is generally in addition to the buyer’s planned down payment and closing costs. Buyers should not promise to cover a gap without confirming that they have the funds and that using them will not interfere with loan approval or post-closing reserves.
3. SPLIT THE DIFFERENCE
The buyer and seller may negotiate a compromise.
For example, the seller could reduce the price by $7,500 and the buyer could cover the remaining $7,500. The exact resolution depends on the parties’ priorities and financial ability.
4. REQUEST A RECONSIDERATION OF VALUE
If the report contains an error, overlooks relevant information or uses questionable comparable sales, the borrower may ask the lender about a reconsideration of value.
A strong request should identify specific, supportable concerns, such as:
• Incorrect square footage
• Missing bedrooms, bathrooms or improvements
• An inaccurate description of the property’s condition
• A factual error involving the site or garage
• A relevant comparable sale that was not considered
• A comparable that is materially different from the subject property
Disagreeing with the number is not enough. The request should present objective evidence.
Fannie Mae’s current consumer guidance explains that borrowers may seek a reconsideration of value when they believe an appraisal is unsupported, inaccurate or deficient. The request goes through the lender—not directly from the buyer or real estate agent to the appraiser.
A reconsideration is not a guaranteed increase, and it can take time. Contract, financing and rate-lock deadlines must still be monitored.
5. TERMINATE UNDER AN APPLICABLE CONTINGENCY
The buyer may have a right to terminate if the contract contains an appraisal contingency, financing contingency or loan-program provision that applies to the circumstances.
That right is not automatic. The wording, deadlines and notices matter.
The Multi-Board Residential Real Estate Contract 8.0, commonly used in Chicagoland, includes a financing contingency and permits an Appraisal Addendum to be incorporated into the agreement. The completed contract—not a general assumption about appraisals—determines each party’s rights.
Buyers should consult their Illinois real estate attorney before sending a notice, accepting a compromise or assuming their earnest money will be returned.
WHAT IS AN APPRAISAL-GAP CLAUSE?
An appraisal-gap clause states that the buyer will cover some or all of a difference between the purchase price and appraised value.
The commitment may be written in several ways:
• Buyer will cover the entire gap.
• Buyer will cover a gap up to a stated dollar amount.
• Buyer will proceed as long as the appraisal reaches a specified minimum value.
• Buyer and seller will use an agreed formula if the appraisal is low.
• Buyer waives an appraisal-related protection entirely.
These terms do not mean the same thing.
For example, an offer at $500,000 with a $10,000 appraisal-gap commitment may provide significantly different protection than an offer stating that the buyer will purchase regardless of appraised value.
The language should clearly establish:
• The maximum additional cash the buyer is promising
• Whether the purchase price changes
• Any minimum acceptable appraisal
• What happens if the gap exceeds the agreed amount
• Applicable deadlines and notice requirements
• Whether financing protections remain in effect
IS AN APPRAISAL WAIVER THE SAME AS NO APPRAISAL?
Not necessarily.
The phrase appraisal waiver can create confusion because it may describe two different situations.
A lender may determine that a traditional appraisal is unnecessary based on its underwriting system. That is a lender-issued valuation waiver.
A buyer may also waive a contractual right connected to the appraisal. The lender may still order an appraisal, but the buyer may have agreed not to use a low value to renegotiate or terminate.
Before waiving anything, the buyer should ask the lender, real estate agent and attorney exactly what the term means in that transaction.
HOW CAN BUYERS PREPARE BEFORE MAKING AN OFFER?
Before including an appraisal-gap commitment, buyers should:
• Review nearby comparable sales with their agent.
• Ask the lender how a low appraisal would affect the loan.
• Confirm the amount of cash available beyond the down payment and closing costs.
• Preserve an emergency reserve after closing.
• Decide the maximum gap they could cover comfortably.
• Have the proposed contract language reviewed carefully.
• Understand what happens to the earnest money if the appraisal is low.
• Avoid assuming that the seller will renegotiate later.
In Oswego, Plainfield, Yorkville, Aurora, Naperville, Joliet and surrounding communities, properties that appear similar online may differ in municipality, school district, subdivision, lot, tax history, condition, improvements or association amenities. Those differences can affect both a buyer’s offer strategy and the appraisal analysis.
DOES A LOW APPRAISAL MEAN THE DEAL IS OVER?
No. Many low-appraisal situations are resolved.
The parties may agree on a new price, divide the gap or proceed under the original terms. A reconsideration may correct a supported error. In other cases, termination may be the most financially responsible option if the contract permits it.
The important point is to make the decision with complete information—not under pressure and not based on assumptions about what the lender, seller or contract must do.
THE BOTTOM LINE
A low appraisal creates a financing and negotiation issue, but it does not dictate one automatic result.
The buyer’s options depend on the loan, available cash and exact contract language. Before offering appraisal-gap coverage or waiving appraisal protections, buyers should understand the largest amount they could be required to contribute and how that commitment affects their right to terminate.
My role is to review comparable sales, explain the practical offer choices, coordinate with the lender and keep the buyer’s attorney informed so the client can make a calculated decision—not an accidental one.
