Home appraisal process and appeals

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
