Recommend having an attorney review it to confirm.If the PMA has legally expired, then the PMC is in the wrong - although they may still have claims for covering the legal expenses.

Making such a hasty decision on two weeks worth of knowing these people as your customers seems like a rash decision to me, but I don't know exactly what's going on, and sometimes personalities just do not mix well together.

Family owned, great reviews.

Lets review some major points as they are pertinent to my advice.1.  

Review your prior year income statement.How did your year go?

So I get your hesitation to be too demanding and your desire for the problems to go away as fast as they can, however since you have NO property manager ( I don't use one either), it is incumbent that you take a more ACTIVE approach with management of your property.Let's review your situation.  1st time leak occurred, you sent a plumber over to find the problem.  

Craig, I'd be happy to review your docs and deal for you and get you to a servicer.

Have you contacted the Zoning Department to review the survey and ask what your subdivide options are with the existing improvements?

Quote from @Chris Seveney: @Charlene Kingsnorth have you had an sec attorney also review what you are doing as if you're are having multiple people as part of a loan participating in it depending on the state this could get you in hot water - so be careful  good point Chris some state allow fractionalized deed of Trust mortgages other do not or require PPM like documents prior to offering them..

I'd be happy to review and price it out.
