Heck do proof of life and show a dated newspaper or speak of a current event that happened to ensure it is that date. 

I'm not an expert and would definitely recommend speaking with a CPA or tax attorney to ensure this is the best fit for your situation. 

@Adam HoakEverything Aron said is perfect also consider If your able to execute and purchase ensure to a certain extent that the area is either up and coming or stable.

There is substantial equity so can a lawyer ensure that I recover any money I invest (paying off the lien and property renovations) through renting it out and/or an eventual sale?

I understand, the foreclosure process will need to respect the existing lease. but, right after confirmation of sheriff sale, what is the process to ensure the current tenant start paying the rental to new owner.Thanks,Kevin

Whenever you are buying a property out of state you should do a few things to ensure it's as smooth as possible.

Just be sure to get the property inspection to ensure everything is in tact (so hopefully nothing goes out at month 13), but otherwise, I think it sounds solid to me!

It's supposed to ensure there are no surprises after closing.

So this ensures privacy as well as avoiding the “due on sales” clause.  

Do something to ensure you have a competent person on your team. 2.
