Can anyone tell me a website I can go to research previous owners of a home?

Answer 1

If you are ready to pay, just type "property title search" in Google and you'll get tens of links
(e.g., http://www.Intelius.com will give you reports for about $15).

The following link gives you hints, how you can get this info for free:

Answer 2

Sitex.com

I know you will need to sign up but I don't know what they charge we used it at my last job and it tells you the name of the last owner and how much they bought the house for.
