Home Appraisals in Illinois: What Buyers and Sellers Need to Know

What Is a Home Appraisal and Why Does It Matter?

A home appraisal is a professional opinion of value, conducted by a licensed appraiser, that determines how much a property is worth based on recent comparable sales and property condition. For buyers financing a home purchase, the appraisal is a lender requirement — the bank won’t lend more than the appraised value, because the home is the collateral for the loan. For sellers, the appraisal is the moment of truth: does the agreed-upon sale price align with what an objective professional says the home is worth?

Understanding how appraisals work — who orders them, what appraisers look at, what happens if the value comes in low, and how to respond — is essential knowledge for both buyers and sellers in the Illinois south suburban market.

Who Orders the Appraisal?

The appraisal is ordered by the buyer’s lender — not by the buyer or seller directly. The lender selects a licensed independent appraiser (or uses an appraisal management company) to conduct the valuation. Federal lending regulations require lender independence from the appraisal process; neither the buyer nor the seller can select or influence the appraiser.

The buyer typically pays the appraisal fee as part of their closing costs, usually $450–$650 for a standard single-family home in the south suburban market. The buyer has a right to receive a copy of the appraisal report from their lender.

What Appraisers Look At

The Sales Comparison Approach

For most residential properties, the primary valuation method is the sales comparison approach — the appraiser finds 3–6 recently sold comparable properties (“comps”) and adjusts the sale prices of those comps up or down to account for differences between them and the subject property. The adjusted values are then reconciled into a final opinion of value.

Key comp selection criteria:

• Location: Comps should be in the same neighborhood or immediate market area, within the same school district
• Recency: Comps should have closed within the last 6–12 months (appraisers prefer 3–6 months)
• Physical similarity: Similar square footage, bedroom/bathroom count, garage, basement finish, and property type
• Condition: Appraisers make condition adjustments — a renovated comp gets adjusted downward when compared to an unimproved subject property, and vice versa

Property Condition Assessment

The appraiser physically inspects the property and assigns a condition rating on a standardized scale (C1–C6 for FNMA/Freddie Mac loans, where C1 is brand new and C6 is substantial deferred maintenance). Condition directly affects value — a C3 (well-maintained, some minor updating needed) property may be worth 5–10% more than a C4 (updating needed, functional but dated) property that is otherwise identical.

Appraisers look at:

• Roof condition and age
• HVAC systems (functioning, age)
• Kitchen and bathroom updates or dated finishes
• Foundation and structural condition (visible)
• Deferred maintenance (peeling paint, damaged trim, broken fixtures)
• Basement finish quality and permitted status

What Appraisers Cannot Consider

Federal Fair Housing law prohibits appraisers from considering the racial or ethnic composition of a neighborhood, the religion of residents, or other protected characteristics. Appraisers are also prohibited from considering the sex, national origin, or family status of the property’s occupants. These prohibitions exist because of a documented history of racially discriminatory appraisal practices — and they are actively enforced by lending regulators.

What Happens If the Appraisal Comes In Low?

A “low appraisal” — where the appraised value comes in below the agreed purchase price — is one of the most stressful moments in a real estate transaction. Here’s what typically happens and what the options are:

The Lender’s Position

The lender will lend based on the lesser of the appraised value or the purchase price. If the purchase price is $310,000 and the appraisal comes in at $290,000, the lender’s loan is based on $290,000. The buyer must cover the $20,000 gap in cash (an “appraisal gap”) or the deal must be renegotiated.

Option 1: Seller Reduces the Price

The most common resolution: the seller agrees to reduce the sale price to the appraised value. This is often the path of least resistance, particularly if the seller is motivated and the buyer has an appraisal contingency protecting their earnest money.

Option 2: Buyer Covers the Gap

If the buyer has agreed to an “appraisal gap clause” or simply has the cash available, they can pay the difference between the appraised value and the purchase price out of pocket. This keeps the deal at the agreed price and the seller whole.

Option 3: Split the Difference

Buyer and seller negotiate a compromise — the seller reduces price partway and the buyer covers the remaining gap in cash. This is common when neither party wants the deal to collapse and both have some flexibility.

Option 4: Challenge the Appraisal (Reconsideration of Value)

If there’s legitimate basis to believe the appraiser used inferior comps or made factual errors, the buyer (through their lender) can request a Reconsideration of Value (ROV). The ROV process allows submission of alternative comparable sales that the buyer and seller believe better support the agreed price. The appraiser reviews the submitted comps and may revise the value upward — or may not. ROVs succeed when there are genuinely better comps that the appraiser overlooked; they rarely succeed when the appraisal was simply accurate but disappointing.

Option 5: Walk Away

If the buyer has an appraisal contingency and the parties cannot agree on how to bridge the gap, the buyer can exercise the contingency, cancel the transaction, and receive their earnest money back. This is the nuclear option — everyone walks away without a deal.

How South Suburban Sellers Can Prepare for Appraisal

• Provide your own comp list: Before the appraisal, give your agent a list of 3–5 recent sales you believe support the purchase price. Your agent can provide this to the appraiser at the inspection — appraisers may or may not use the comps, but having them available ensures the appraiser is aware of sales that support value.
• Document improvements: Prepare a list of significant updates made during your ownership — new roof year, HVAC replacement, kitchen renovation, bathroom updates — with approximate costs. Appraisers account for updates; documented updates are better than verbal claims.
• Make the property accessible and presentable: The appraiser visits the property in person. Clean, clutter-free rooms allow the appraiser to accurately assess square footage and condition without being distracted by disorder. A dimly lit, cluttered basement gets a worse condition rating than a clean, well-lit one.
• Fix visible deferred maintenance: Items that suggest neglect — peeling paint, broken light fixtures, cracked windows — can lower the condition rating even when the underlying home is sound. Addressing these before appraisal is a low-cost way to protect your value.

Frequently Asked Questions: Home Appraisals in Illinois

How long does a home appraisal take in Illinois?

The physical inspection typically takes 30–90 minutes depending on property size. The written appraisal report is usually delivered to the lender within 5–10 business days of the inspection. Total time from appraisal order to report delivery varies by market demand for appraisers — in busy markets, scheduling can add a week or more.

What happens if the appraiser can’t find good comps in the south suburban market?

In slower-moving south suburban markets with few recent sales, appraisers may need to extend their geographic search radius or use older sales (with time adjustments). This is where low appraisals are more common — in thin markets, the comp base may not fully support prices where buyer demand has outpaced comp availability. Your agent should be aware of this risk and prepare accordingly.

Can I be present during the appraisal inspection?

Yes, as the seller you can be present. It’s appropriate to briefly provide the appraiser with your list of improvements and recent sale comps. Don’t hover or pressure the appraiser — they’re conducting an independent assessment. A brief, professional exchange is welcome; excessive salesmanship is counterproductive.

Does a finished basement count toward appraised square footage in Illinois?

Generally, below-grade finished square footage (basement) is valued separately from above-grade living space and typically at a lower per-square-foot value. A finished basement adds value — it’s just not dollar-for-dollar equivalent to above-grade square footage in the appraisal framework. This varies by appraiser, local market norms, and the quality of the basement finish.
