Some places to find the history of a home’s previous owner include checking real estate sites, getting a house report and looking into public records and local permits. Interested parties cal also ask neighbors or a real estate professional about the previous owner.
Real estate sites such as Trulia, Homes.com and Zillow allow the user to look up an address and see who owned the house previously. While these sites don't provide the former owners' personal information, they show when the house was sold previously or if it had just one owner.
A house report includes information about the age of the property, building permits and public records in regards to the house in question. The courthouse typically also has public records about houses, including blueprints and the original building permit, which might have the name of the previous owners.
