A home is worth what someone will pay for it. Everything else is an estimate of value. To determine a property's value, most people turn to either an appraisal or a comparative market analysis. An appraisal is a certified appraiser's estimate amenities, energy efficiency, the quality of the of the value of a home at a given point in time. To make their determination, appraisers consider square footage, construction quality, design, floor plan, neighborhood and availability of transportation, shopping and schools.
Appraisers also take lot size, topography, view and landscaping into account.
A comparative market analysis is an informal estimate of market value, based on comparable sales in the neighborhood, performed by a real estate agent or broker. You can do your own cost comparison by looking up recent sales of comparable properties in public records. These records are available at local recorder's or assessor's offices, through private companies or on the Internet. Dataquick Information Systems tracks home sales statewide and prepares reports for specific properties. Also, check the Internet where CAI operates an informative site as does CIDNetworks.
