You can get some idea of your home's value by searching the Internet. A number of Web sites and services crunch the numbers from historic public records of home sales to produce the statistics. Some services offer an actual estimate of value based on acceptable software appraisal standards. They also depend on historic home sales records to calculate the estimate.

Neither of these services produce official appraisals. They also don't factor in market nuances or other issues a certified appraiser or real estate professional might in assessing the value of your home. These are, however, a great way to get a general idea of what your home is worth.
