Appraisal
Appraisal
Quick Definition
A real estate appraisal is a professional, independent estimate of a property's fair market value conducted by a licensed or certified appraiser. Mortgage lenders require an appraisal before approving a purchase or refinance loan to verify that the property value supports the loan amount. The appraisal protects both the lender (ensuring adequate collateral) and the buyer (confirming they are not overpaying relative to comparable sales).
What It Means
When a lender agrees to finance a $500,000 home purchase, they are lending against the property as collateral. If the borrower defaults, the lender needs to recover the loan balance through foreclosure. An appraisal ensures the property is actually worth what the contract says — protecting the lender from financing a $500,000 loan on a home worth only $430,000.
For buyers, an appraisal that comes in below the purchase price (a "low appraisal") is a significant event — it forces a renegotiation, a cash payment of the difference, or termination of the sale.
How an Appraisal Works
| Step | Description |
|---|---|
| Lender orders appraisal | From an independent, licensed appraiser on the lender's approved panel |
| Property inspection | Appraiser visits the property; photographs interior and exterior; notes condition, size, features |
| Comparable sales analysis (comps) | Identifies 3-5 recently sold similar properties in the area |
| Adjustments | Adds or subtracts value for differences (garage, extra bathroom, pool, condition) |
| Final value opinion | Reconciles approaches; states concluded market value |
| Report delivery | Written appraisal report delivered to lender within 1-2 weeks |
The Three Approaches to Value
Appraisers typically use one or more of three approaches:
| Approach | How It Works | Best For |
|---|---|---|
| Sales comparison approach | Compare to recent sales of similar properties; adjust for differences | Residential homes; most common |
| Cost approach | Estimate land value + cost to rebuild minus depreciation | New construction; special-use properties |
| Income approach | Capitalize net operating income (NOI ÷ cap rate) | Income-producing property; rentals |
For standard residential homes, the sales comparison approach is primary — appraisers find the most similar recently sold homes and make dollar adjustments for differences.
Comparable Sales Adjustments: How Appraisers Think
Example: Subject property is a 3BR/2BA, 1,800 sq ft, no garage.
| Comparable | Sale Price | Size Adj. | Garage Adj. | Bedroom Adj. | Adjusted Price |
|---|---|---|---|---|---|
| Comp 1: 3BR/2BA, 1,900 sq ft, 2-car garage | $480,000 | -$10,000 | -$20,000 | $0 | $450,000 |
| Comp 2: 3BR/2BA, 1,750 sq ft, no garage | $430,000 | +$5,000 | $0 | $0 | $435,000 |
| Comp 3: 4BR/2BA, 1,800 sq ft, 1-car garage | $460,000 | $0 | -$10,000 | -$10,000 | $440,000 |
| Indicated value | ~$442,000 |
Each adjustment reflects the market's reaction to that feature — what buyers are actually paying more or less for.
When an Appraisal Comes In Low
A low appraisal occurs when the appraised value is below the contract purchase price — a significant event requiring resolution:
| Option | Description | Who Initiates |
|---|---|---|
| Renegotiate price | Seller reduces price to meet appraised value | Buyer requests |
| Buyer pays difference | Buyer brings extra cash to closing (pays above appraised value) | Buyer decision |
| Split the difference | Partial price reduction + partial buyer cash | Negotiated |
| Appraisal rebuttal | Buyer/agent challenges appraisal with better comps | Buyer |
| Second appraisal | Order another appraisal; lenders rarely allow this easily | Complex |
| Cancel transaction | Buyer invokes appraisal contingency; gets earnest money back | Buyer's right |
Appraisal contingency: Most purchase contracts include an appraisal contingency — the right to cancel if the appraisal comes in below a specified amount. Without this contingency (common in competitive markets), buyers are obligated to complete the purchase even if the appraisal is low.
Appraisal vs. Assessment vs. Automated Valuation
| Type | Conducted By | Purpose | Legal Standing |
|---|---|---|---|
| Appraisal | Licensed appraiser | Mortgage lending; legal disputes | Highest — professional opinion |
| Property assessment | County assessor | Property tax calculation | Governmental; may differ from market value |
| Automated Valuation Model (AVM) | Algorithm (Zillow Zestimate, etc.) | General reference | Lowest — no property inspection |
| Broker Price Opinion (BPO) | Real estate agent | REO/short sale pricing | Moderate — not accepted for most mortgages |
Zestimate vs. appraisal: Zillow's Zestimate is an AVM — it uses public records and algorithms with no property inspection. Median error rate is ~2-3% nationally but can be 10-20% off in specific markets or for unique properties. It is a reference tool, not a professional valuation.
Appraisal Costs and Timeline
| Item | Details |
|---|---|
| Cost (residential) | $350-$700 (single family); $500-$1,500 (complex/large) |
| Timeline | 5-14 days from order to delivery |
| Who pays | Typically the buyer (or borrower for refinance) |
| When paid | Usually upfront before closing, or at closing |
Key Points to Remember
- Appraisals are required by mortgage lenders to verify property value supports the loan amount
- The sales comparison approach using 3-5 recent comparable sales is primary for residential homes
- A low appraisal forces renegotiation, extra cash from buyer, or cancellation under the appraisal contingency
- Appraisals ≠ assessments — property tax assessments are for tax purposes and often differ significantly from market value
- Automated valuations (Zillow Zestimate) are reference tools only — not professional appraisals
- Appraisals cost $350-$700 and take 5-14 days; the borrower typically pays
Frequently Asked Questions
Q: Can I challenge a low appraisal? A: Yes — called an appraisal rebuttal or reconsideration of value (ROV). Provide your agent's evidence: recent comparable sales the appraiser missed, factual errors in the report (wrong square footage, missed features), or sales that better represent the property's value. The lender submits the rebuttal to the appraiser. Success rate is modest — appraisers rarely change their opinion without compelling new evidence. Procedurally, the appraiser must consider but is not required to change the value.
Q: Does an appraisal protect me from overpaying? A: Somewhat. The appraisal reflects market value based on comparable sales — it tells you what similar properties have sold for. If the appraisal matches the contract price, it validates that the price is in line with the market. However, appraisals are backward-looking (based on past sales) and can lag in fast-rising markets. In a rapidly appreciating market, paying modestly above appraised value may be rational if values are trending up.
Q: Do I get a copy of the appraisal? A: Yes — federal law (ECOA) requires lenders to provide borrowers with a copy of any appraisal obtained in connection with a credit application, at least 3 business days before loan closing. You should request and review it before closing to verify the information is accurate (correct square footage, features, condition noted).
