Keep walking.

Could you make 10 or 100 videos for a business you could walk to today?   

If they spring something on you at the closing table, run, don't walk, away.

EB is great source of renters with solid incomes and I have found that our EB renters seem to prefer our listings in Groton being closer to EB and in some cases walking distance.

X dollars to get the goods they had and if they were unwilling to do exchange I immediately walked out.

Would you feel safe walking around?

As Chris noted, for all the news about how terrible they are, and a little of it is true from my post-COVID experiences walking around SF, NYC and LA, a lot of it, I think is blown a bit out of proportion.  

On the rehab I would maybe pay a GC to walk a few properties with you so you can learn and understand the costs.

so after reading all the posts, it sounds like his best bet is just to move on and walk away finding another place maybe coming back in future to keep contact with that person if he really wants that location… Correct me if I’m wrong, but my analysis from all this is that hiring a squatter would only be applicable in situations where the person who is occupying the residence never had a lease or contract therefore it is a rare circumstance where it would be a viable option. 

You can lower the price.The buyer can pay the extra $9k in cash, if they have it.The buyer can walk away with their earnest money and you can lower the price $9k for the next buyer or require them to bring $9k in cash.
