CMAs are generated from multiple listing service software and vary greatly depending on the search fields that are input by the real estate professional. Each quantifier makes the search increasingly specific - type of home (detached vs. attached), zip code, number of bedrooms, baths and living areas, square footage, and numerous other search criteria.
The result is a report that tells you which homes have recently sold, their selling prices, how long they were on the market and other information. The CMA will also tell you about homes in competition with yours that are similar in size, price, amenities, and location.
