They asked me how much activity I wanted on the account and whether I needed checks / atm access, etc and I clarified again that I simply needed a traditional escrow account, non-commingling of funds, to hold their money.  

Plan B, I would need to get back to callers in a reasonable amount of time before the leads go stale.If I go with Plan B I might be able to go with traditional financing.

We have obviously already discussed the traditional options (i.e. bank loans, FHA/HUD, our own savings), but we are currently brain storming some non-traditional and creative ways to finance the project. 

If you OF both the home and land you can sell for a lot more because it's like traditional single family and can sell based on $/sqft and there are MLS comps. 

will it work as a regular traditional mortgage?

Jared Christian what was the goal of the purchase (wholesale, flip, rental)?

You haven't paid for the rest, so you don't own it...yet.This is different than a traditional buy where you buy money (sometimes called a loan...for some odd reason) from a lender, and use that money to pay the seller in full for the property. 

@Nicholas AlvesThere might be business accounts available for those apps but traditionally, the tenant pays with a check or money order made out to the LLC.

The other thing is the measurement of inventory in months as traditional, is going to skew things quite a bit.

If not and your having a partner maybe have them come in sooner and use them for access to more traditional lending.Best of luck!
