Once you incorporate in your state, you can get a federal tax ID and a bank account.

One thing you do have to worry about is they normally have an out clause if they lose federal funding where they can cancel with 60-90 days notice. 

We delivered the logs... paid off the Timber deed.. now we have made 200k large.. and own the ground free and clear.Took the top 40 busted it into 4 10's sold those for 125k each to home owners.. then METRO ( quasi government agency ) came in and bough the lower 120 from us for 1.1 million.. its now the Cooper Mtn..

If your still residing in the property then government and conventional financing would be available. 

Hi Debbie,That sounds like a really awesome setup and bravo to the local government to allowing this!

Or does the small footprint and lack of utilities basically make them glorified tents as far as the government's concerned?

I’m being told it’s due to Federal lending regulations?

I'd check with your local government to see what kind of programs they have for improving neighborhoods.  

I keep a spreadsheet of who will lend to LLCs and here's who I'd recommend:Servis1st BankCB&TSunmarkColony BankHere's some more that I haven't gotten around to asking yet:Heritage Bank of the SouthAmerican PrideState Bank & TrustMidSouth Federal CUBB&TAnother option is to put the building in your personal name and get a conventional loan....but then you are opening yourself up to all kinds of personal liability (times 10 since there are 10 units).You could also start asking about a regular business loan.  

Some states don't have specific laws on them, but Federal law still applies.
