Your home's assessed value and market value are each determined by different factors. Buyers and sellers affect the market value of a home, while professional appraisers calculate the assessed value. In a seller’s market, your home’s market value may be higher than its assessed value. That’s because buyers are willing to pay more than the home is technically worth because of low inventory. In a buyer’s market, you’ll be facing a lot of competition from other sellers, so buyers may put in an offer lower than the home’s assessed value.
