Comparative Market Analysis (CMA) is a vital tool in real estate that helps agents and clients understand the value of a property in relation to similar properties in the market. It involves analyzing recent sales of comparable properties, active listings, and expired listings to determine a property's potential value. CMA matters because it provides crucial insights for both buyers and sellers. For sellers, it helps in setting the right listing price, and for buyers, it offers confidence in the market value of a property they are interested in. The CMA process involves gathering and analyzing data, identifying comparable properties, and making adjustments for differences to arrive at an accurate valuation.
