I recommend educating yourself as best you can to avoid some common mistakes.

The trade-off is losing out on potential growth from a reinvested 1031 exchange, but if you’re thinking about a HELOC later to invest again, this could bridge the gap.What I’d do in your shoes:If it were me, I’d run the numbers on a worst-case scenario for each option.

Have 2-3 contractors look at the job and get written estimates on what it's going to take to finish the job, correct the mistakes, pass occupancy certification etc. use those estimates in your countersuit / mediation process. 4.

I always tell clients it costs me zero $$ to send an offer and worst case they decline.
