I then opened a complaint with the county who has issued him a notice of correction (front yard junk and feces) but I’m not sure where that will go as the notice is addressed to him wife (who seems to no longer live that the property) who records list as the sole ownerAny suggestions?

It was nice at first as I was able to travel up and down the east coast visiting military friends I hadn't seen for a while and not having to worry about maintaining a yard or a house.

How do I look up if a offer or a purchase has been made on a property?

Late payments, high credit utilization, derogatory public records, collections?  

You would have ongoing filing requirements with the State and would need to keep business records and documentation. 

Better bang for your buck if you're willing to travel a little. 

Also, from a public records search, I can see that the bank has filed a law suit against the owners for nonpayment of their debt.My questions are:What is the best way to approach this deal?

I travel a majority of the year volunteering with a non-profit organization.

Healthy portfolio, good paying job and have travelled extensively. 

You have to record it though.
