If you are not getting a response, it is possible they have no interest in talking to you about it.

To be fair it's possible that the home inspector explained that it's not up to current code but that it doesn't have to be, and the buyer/ buyer's agent may have misunderstood that to mean there is actually a problem with the deck. 

Water leaks are a big deal, I would act as quickly as possible. 

Is it not possible that you could get 4 non veterans as tenants?

Sorry to be the bearer of bad news, but when you look at the facts of what money was invested in and how it was handled, it leaves little to hope for.The only potential to get anything back is a potential SEC / FBI investigation to see if any fraud was at play where other assets of Norada is possibly garnished to pay back investors.

Is it possible to navigate these regulations and make a lake house or cabin rental work?

You may need to seek legal counsel on this.2) Get all the info about your rental property as possible: leases, rent ledgers, tenant contact info, etc.3) Start looking for a new PMC4) Execute your termination notice5) Once transfer is complete, circle back to decide if worth suing them.

My target purchase price is ideally under $150k as my long term goal is to pay them off as quickly as possible.

@Satyajeet Dodia, I agree if possible you should have your properties owned by an LLC. 

If possible you could even pay down another month on your investment property as well.
