Driving for dollars....now I have questions

[John Turner]

I've identified 2 properties I would like to pursue further. I need help with my next steps.

Property A:

Foreclosure with a "gun aggessive" tenant according to the real estate agent. I don't know if the inside of the house is in any decent shape because of the tenant. There's no pictures. That being said, the land and established septic and water would be worth what I will offer. 

My question is, how do I offer to buy the property? Can I make it contingent the tenant is gone? Adding to that, I would be fine to pay the tenant say $500 to leave the place in good shape. Can I put that in the offer?

I know I could make the offer contingent upon inspection but they would have to get him out for us to inspect I think. Advice gladly welcomed. This is a property in the US and I am investing from Canada.

Property B: 

This property is vacant and the information says it is down to the studs. It has been empty for some time. The listing is gone. How do I find out who owns it?  This is a property in the US and I am investing from Canada.

Thanks to anyone who can give me some tips on how to proceed.
