Since were’re talking about database technology, it seems to me that Sandicor isn’t in the business of providing accurate information. They are looking to slant data for the benefit of its membership.
The MLS could easily track sales and listing information using the parcel number and thus easily provide sales and listing history on a specific property since that parcel creation.
I would think that a buyer would be interested in the total sales history of a house. We need an open “carfax for houses” that would integrate sales and MLS information.
