Contingency lawyers are not interested because of Arbitration clauses in the contract.

I’m considering having a lawyer send them a certified letter, though I know that will still come with a significant fee, which is still preferable to full service.

Hopefully your lawyer also mentioned insurance- title and hazard.A quitclaim deed transfer can hurt your title chain and title insurance. 

Hiring a lawyer sounds expensive, but it is way cheaper than hiring a amateur (in this case yourself) who costs you money and provides no results (and then you need to hire a professional anyway).My personal philosophy is to "do it right, or do it twice" and its way cheaper to do it right once. 

One tenant screamed at my husband threatened lawyers the whole 9.

They all had their own lawyers of course and it was a mess that took 3 years but eventually the buyer (the developer) did prevail.

Learn the eviction procedure for your area, perhaps contact a lawyer in the field to help you with this one, and get the fraudster you're currently housing out on the sidewalk to sleep in a cardboard box where they belong.You're going to lose plenty of money here, but this will never happen to you again, and you can minimize your losses if you move as quickly as possible.

My question is can anyone point in the direction of someone who could represent me in this matter maybe a lawyer or attorney, or someone who knows the fire code and who can be clear and concise on what I need.

How many lawyers did you consult with?  

I would also reach out to real-estate friendly lawyers to help you draft the necessary documents to form an LLC and to talk through the pros/cons for various decision.Also, I'm curious why you decided to invest in BHAM.
