Maximizing time and benefit when going to the county offices

[Kyle McCane]

Hi all, 

What do you look for when doing research at your county offices?

In my case I've been doing some driving for dollars and have identified multiple properties that are of high interest. 

I'd like to maximize my time and value when I go to the county offices. I'm assuming a couple of things that I can get:

1. Current ownership information 

2. If absentee owner, gaining that owner's address and contact information

3. Tax information (available online in my county)

4. Lein info (available online)

5. Other property history?

What other info should I be looking for?

Thanks for the help.
