I want to make sure I understand every step involved in this process.

To properly value a park requires a fairly deep understanding of how they will operate, given all the potential variables.

Obviously, based on my relationship with the company, I'm not unbiased, but most people here on BiggerPockets know that I value my reputation above all, and when I agreed to join FTF as an advisor a couple years ago, it was because I was very impressed not only with their business model and underwriting guidelines, but with the CEO (Matt Rodak) and the rest of the management team.I have no requirement to invest my own money on the FTF platform; I do that simply because I like the platform, like the deals that are being funded and find the returns to be nearly as good as the private lending I do, but without all the overhead. 

For my single families I follow similar rules that you mentioned, but my understanding is for apartment buildings that a cost per unit is usually used.

There's less people buying 2 flats, therefore there's not as much competition to buy.

First, it seems weird and possibly illegal for people at the county level to threaten to remove a state licensed contractors license and threaten it over 6k. honestly I would take 1k from the possible 6k in question and hire a lawyer.

Now, a lot of people call and ask me what it takes to get a project like this done. 

I’m trying to understand if this situation is normal and if it's worth my time to pursue the tenants for the lost rent and damages.

And laugh at people that ask what your fax number is.

I saw some reviews where people loved them and others hated them.
