Appraisal explained
An appraisal is a formal valuation of a property carried out by a licensed or accredited appraiser who inspects the home and compares it to recent sales of similar properties nearby. The appraiser considers location, size, condition, upgrades, and market trends to arrive at an opinion of fair market value, documented in a written report.
Lenders rely on appraisals to manage risk: the mortgage is secured against the property, so the lender wants assurance the home is worth at least what it is lending. If an appraisal comes in below the agreed purchase price, the lender bases the loan on the lower value, which can leave the buyer needing to cover the shortfall in cash.
