Step one: gather the facts the visit cannot show
Collect records that explain value but are not obvious on a walkthrough: permits, receipts for roof, HVAC, window or kitchen work, warranty papers, survey details and a short list of upgrades with approximate dates. Example: a homeowner who finished a basement two years ago assembles the permit, contractor invoice and a floor plan with square footage. Place these in one folder or digital file so they can be handed over at arrival. Accurate documents help the appraiser avoid guesswork, and they keep the conversation about verifiable improvements instead of memory or opinion.

Step two: make every area easy to inspect
Clear access to the attic, crawl space, utility room, garage, electrical panel and water heater. Replace burned-out bulbs, confirm that every appliance included in the sale or loan works, and unlock gates and outbuildings. In the basement example, move storage away from walls so finished areas, egress windows and mechanical equipment are visible. Tidy rooms so layout and condition are clear, without staging so heavily that features are hidden. Fix small, inexpensive defects like dripping faucets or damaged trim, because visible maintenance issues can distract from the condition of the home overall.

Step three: brief the appraiser and follow up
Prepare a one-page summary listing bedrooms, bathrooms, finished areas, major updates and any recent comparable sales you know of nearby, labeled as information to consider, not demands. Meet the appraiser, answer questions, and avoid pressuring about a number. In the example, the owner points out the finished basement and offers the permit. Afterward, ask when the report is expected and who receives it. If a factual error appears, such as wrong square footage, submit supporting documents through the proper channel promptly and keep copies of every exchange.
