When you're buying or selling a home, you'll hear talk of appraisals and inspections as if they're interchangeable—but they're fundamentally different processes that serve different purposes. A lender won't fund your mortgage without an appraisal; a home inspector won't tell you the property's market value. Understanding what each one actually does will save you time, money, and confusion during your transaction.
What a Residential Appraisal Actually Does
A residential appraisal is a professional estimate of your home's market value, ordered and paid for by the lender (usually $400–$600 in most markets, though it varies by location and property type). An appraiser—a licensed professional with specific training and credentials—visits the property and produces a formal report that the lender uses to decide whether the home's price matches its actual value.
The appraiser examines the home's condition, size, location, recent comparable sales in the area, and any upgrades or defects. They're not looking for problems to fix; they're calculating what the property is worth in the current market. If you're buying a $300,000 home but the appraisal comes in at $280,000, your lender will only loan 80% of that lower figure—meaning you'd need to cover the $20,000 gap yourself or renegotiate the purchase price.
What a Home Inspection Does
A home inspection is a detailed physical examination of the property's systems and structure. The buyer typically orders and pays for this inspection ($300–$500) to identify any defects, repairs, or safety issues before closing. An inspector checks the roof, foundation, plumbing, electrical, HVAC, and more—then provides a detailed report of what's working, what's failing, and what needs attention.
Unlike an appraiser, an inspector doesn't assign a dollar value. They answer the question: "What's wrong with this house?" You might learn the roof has 5 years of life left, the furnace is failing, or there's hidden water damage. This information gives you leverage to negotiate repairs, request credits at closing, or walk away if problems are too costly.
Key Differences at a Glance
| Aspect | Appraisal | Inspection | |--------|-----------|-----------| | Purpose | Determine market value | Identify defects and repairs | | Ordered by | Lender (required) | Buyer (optional, but strongly advised) | | Cost | $400–$600 | $300–$500 | | What it answers | "What is the home worth?" | "What's wrong with the home?" | | Credential focus | Appraiser license, state-specific training | Home Inspector certification (varies by state) | | Report type | Market-value estimate | Detailed defect list with recommendations | | Affects mortgage? | Yes—directly impacts loan amount | No—but informs your purchase decision |
Why You Need Both (Usually)
Your lender mandates the appraisal because they're protecting their money. If you default, they foreclose on a home that might be worth far less than the loan amount. An appraisal ensures the collateral is solid.
You need the inspection because the lender doesn't care about livability or hidden problems—only value. A home could appraise fine but have a cracked foundation, mold, or failing systems that cost thousands to repair. The inspection is your protection.
Timeline and Practical Steps
Most appraisals are ordered within 3–5 days of offer acceptance and completed within 7–10 days. Inspections are usually scheduled separately and can happen as soon as the offer is accepted; many contracts include a 7–10 day inspection contingency period for you to review findings and negotiate repairs.
Order your inspection early—don't wait for the appraisal. If the inspection uncovers serious issues, you may have grounds to renegotiate or exit the deal. After the inspection, use the report to decide which repairs are deal-breakers and which you can accept or ask the seller to address.

Frequently Asked Questions
Q: What if the appraisal comes in low? You can ask the seller to lower the price, request the appraiser reconsider (rare), cover the gap in cash, or walk away if your loan falls through. Low appraisals often trigger renegotiations.
Q: Can I use the same person for both? No—appraisers and home inspectors have different licenses and training. An appraiser focuses on value; an inspector focuses on condition. You must hire separate professionals.
Q: Do I have to fix everything the inspector finds? No—you can negotiate for the seller to make repairs, accept a credit at closing, or leave defects as-is. The inspection gives you information to make that choice strategically.
