A home appraisal is an independent, professional assessment of a property's fair market value, ordered by the mortgage lender as a condition of loan approval. The lender requires the appraisal to verify that the property is worth at least the loan amount — this protects the lender from issuing a loan larger than the collateral (the home) can support.
61 steps across 12 sections
1. Comparable Sales ("Comps")
- Minimum of 3 recent sales of similar properties nearby (ideally within 0.5-1 mile)
- Sourced from MLS (Multiple Listing Service) and public records
- Adjusted for differences in size, features, condition, lot size, and age
- Preference for sales within the last 3-6 months
2. Property Condition -- Exterior
- Structural soundness (foundation cracks, settling)
- Roof condition (age, leaks, missing shingles)
- Siding, paint, and exterior walls
- Drainage and grading around the property
- Driveway, walkways, and curb appeal
- Garage condition (attached vs detached, number of cars)
- Landscaping and tree maintenance
3. Property Condition -- Interior
- Number of bedrooms, bathrooms, and total rooms
- Total square footage (measured by the appraiser)
- Floor plan and layout functionality
- Kitchen condition (countertops, cabinets, appliances)
- Bathroom condition (fixtures, tile, ventilation)
- Flooring type and condition
- Windows (type, condition, energy efficiency)
- Closet and storage space
4. Systems and Infrastructure
- HVAC system (type, age, working condition)
- Plumbing (pipes, water heater, water pressure)
- Electrical system (panel capacity, wiring type, outlets)
- Insulation quality
- Any evidence of water damage, mold, or pest infestation
5. Features and Upgrades
- Renovations and remodels (kitchen, bath, additions)
- Finished basement or attic space
- Built-in appliances
- Energy-efficient upgrades (solar panels, smart thermostat, new windows)
- Pool, deck, patio, or outdoor living space
- Fireplace, hardwood floors, crown molding
6. Location and Neighborhood
- School district quality
- Proximity to amenities (shopping, parks, transit)
- Neighborhood condition and trends
- Traffic patterns and noise levels
- Flood zone or environmental hazard areas
- View and lot positioning
7. Who Pays
- Buyer pays in the vast majority of transactions (part of closing costs)
- Negotiable — seller can agree to cover it (common in buyer's markets)
- The fee is typically paid upfront before the appraisal is conducted
- If the deal falls through, the buyer usually does not get the appraisal fee back
8. Factors That Increase Cost
- Property size (homes over 3,000+ sq ft)
- Acreage or rural location
- Multi-unit properties (duplex, triplex, fourplex)
- Complex properties (unique architecture, historical homes)
- Rush orders (24-48 hour turnaround)
- Geographic areas with appraiser shortages (the appraiser workforce shrinks roughly 3% per year)
9. Option 1: Renegotiate the Purchase Price
- Ask the seller to lower the price to match the appraised value
- Propose splitting the difference between appraised value and purchase price
- More likely to succeed in a buyer's market or when the seller is motivated
- The listing agent may also push the seller to accept since a low appraisal signals market pricing
10. Option 2: Request a Reconsideration of Value (ROV)
- Formal process to challenge the appraisal (see Section 7 below)
- Must go through the lender — buyers/agents cannot contact the appraiser directly
- Success depends on providing concrete evidence of errors or better comps
- Timeline: 1-3 weeks for lender response
11. Option 3: Use an Appraisal Gap Clause
- A contract provision where the buyer pre-commits to covering the gap up to a specified dollar amount
- Example: "Buyer will cover appraisal gap up to $15,000"
- Requires cash reserves beyond the down payment
- Increasingly common in competitive markets; many sellers expect to see one
12. Option 4: Pay the Difference Out of Pocket
- Buyer brings additional cash to closing to cover the gap
- Does not affect loan terms (lender still lends based on appraised value)
- Only feasible if buyer has sufficient reserves
Common Mistakes
- Not including an appraisal contingency in the offer
- Waiving the appraisal contingency to compete without cash reserves
- Failing to prepare the home for the appraisal
- Not providing the appraiser with an upgrade list
- Using Zillow/Redfin/Realtor.com estimates as actual appraisals
Pro Tips
- Budget for the appraisal gap
- Get your own comps
- Attend (or have your agent attend) the appraisal if permitted
- Keep your appraisal contingency
- Ask your lender about appraisal waivers
