Research the property owner

[Jason Wu]

Fellow BP friends,

If I have an property address, what is the best way to find out the property owner and its contact (phone/owner mailing address/etc)

I know the property is vacant and probably in distress but I cannot have a good way to find the owner.  I tried the tax office and they won't give our that information.  I tried online and there are a couple of pay-services but I just don't know how good they are.

Thanks!
