I'm surprised that from all the people on BP nobody knows the answer

[Pavel Sakurets]

I posted a question before if anyone knew how to find vacant properties besides contacting cities and driving neighborhoods. Shocked that nobody responded with an answer.

We find that only larger cities have these records, but smaller ones do not.

Does anyone know of a service that could locate empty properties?

Also after we find a property, how to find the property owner if his/her county's record is the same mailing address as the property's?
