How appraisals work, what affects the value, and what to do if it comes in low
Your lender orders an appraisal to confirm the home is worth what you're paying. If the appraisal comes in low, your financing is at risk. Understanding how appraisals work helps you prepare and respond.
1How Appraisers Determine Value
Appraisers use the sales comparison approach for most residential properties:
What they look at physically:
- Find comparable sales ("comps") — Similar homes that sold within the last 6–12 months, ideally within 1 mile
- Adjust for differences — Each comp is adjusted up or down for differences in bedrooms, baths, square footage, lot size, condition, and upgrades
- Reconcile to a final value — The appraiser weighs the comps and issues a final opinion of value
What they look at physically:
- Square footage and room count
- Overall condition (excellent, good, average, fair, poor)
- Updates: kitchen, baths, systems
- Lot size, location, and views
- Any deferred maintenance or safety issues
2What Affects Your Appraisal Value
Positive factors:
Negative factors:
What you can't control:
- Recent kitchen or bathroom renovations
- New roof, HVAC, or windows
- Good curb appeal and clean condition
- Strong recent comps in the neighborhood
- Desirable school district
Negative factors:
- Deferred maintenance (peeling paint, broken fixtures)
- Unusual floor plans or non-conforming additions
- Proximity to industrial areas, busy highways, power lines
- Declining neighborhood sales prices
What you can't control:
- The overall market direction
- What your neighbors' homes sold for
- Interest rate environment (affects comp volume)
3If the Appraisal Comes in Low
A low appraisal doesn't automatically kill the deal. You have options:
Option 1: Renegotiate the priceThe most common outcome — the seller drops the price to the appraised value. In a buyer's market, this is expected.
Option 2: Pay the gap in cashIf you love the home and have the cash, you can pay the difference between the appraised value and the purchase price. This is more common in competitive markets.
Option 3: Challenge the appraisalIf you believe the appraiser missed relevant comps or made factual errors, your agent can request a Reconsideration of Value with supporting evidence. This works roughly 20–30% of the time.
Option 4: Walk awayYour appraisal contingency protects you. If the appraisal is low and the seller won't budge, you can exit and recover your earnest money.

Pro Tips
- Ask your agent to pull comps before the appraisal — have a list ready if the appraiser asks
- A tidy, well-maintained home inspects better than a messy one (even if price isn't supposed to matter)
- Appraisals are opinions, not science — the same home can appraise differently by different appraisers
- In refinances, you can request the appraiser's contact info and provide your own comp list
