I recently masterminded with a vary high net worth individual.

Acquiring legal title to the replacement property under the individuals' names for loan purposes would likely be deemed to be a completely different taxpayer than the four member LLC and the 1031 Exchange would be disqualified. 

Should I check to determine if they have tax liens; then send letters to the owners on record, indicating I would like to purchase? 

I tried calling the tax office of the county but the individual who answered the phone didn't seem to know and transferred me to a supervisor, for whom I left a VM but hadn't heard back yet.Thanks!

Basically we are wanting to help individuals get back on their feet who might be struggling from a variety of different things. 

There is a misconception contained in your post which is indicative of what a lot of new investors think.

I'm excited to start my REI journey, learn & share as much knowledge with like-minded individuals!

The right thing for the tenant to do is have the moving company arrange and pay for the repairs to the owner’s satisfaction, though there is no indication that he will be taking this approach.To the veteran BP landlords out there, any recommends on managing this so as to get the situation resolved without becoming entangled in a mess between my tenant and the neighbors?

For example, could I sell a 5 million dollar office building and go buy a 10 million dollar portfolio of 100 SFHs that are individually deeded?
