1. An appraisal isn’t an exact science: When appraisers evaluate a home’s value, they’re giving their best opinion based on how the home’s features stack up against those of similar homes recently sold nearby. One appraiser may factor in a recent sale, but another may consider that sale too long ago, or the home too different, or too far away to be a fair comparison. The result can be differences in the values two separate appraisers set for your home.
2. Appraisals have different purposes: If the appraisal is being used by a lender giving a loan on the home, the appraised value will be the lower of market value (what it would sell for on the open market today) and the price you paid for the house if you recently bought it. An appraisal being used to figure out how much to insure your home for or to determine your property taxes may rely on other factors and arrive at different values. For example, though an appraisal for a home loan evaluates today’s market value, an appraisal for insurance purposes calculates what it would cost to rebuild your home at today’s building material and labor rates, which can result in two different numbers.
Appraisals are also different from CMAs, or competitive market analyses. In a CMA, a real estate agent relies on market expertise to estimate how much your home will sell for in a specific time period. The price your home will sell for in 30 days may be different than the price your home will sell for in 120 days. Because real estate agents don’t follow the rules appraisers do, there can be variations between CMAs and appraisals on the same home. (Houselogic 3/12/10)
