Completed an appraisal a few weeks ago for a refinance. Thought all was well until a few days later I received a fax from the lender indicating the homeowners thought the appraised value was low and would I further research the sales. The lender included a printout from an internet site SiteXdata.com and asked why I did not use one of the sales. Good question? It was not in my MLS search at the time I did my initial search. However, when I checked the specific address they requested. There it was. Used it, and updated the appraisal. While this site does not produce a market value for a property, it does indicate a range. Not sure what the cost of this service is, but apparently it is used by some lenders and the data appears to be accurate down to the Deed Book and Page Number of the properties. Just thought this might be of interest to all.
