The plan here is to have a local (RV Certified) tiny home builder do the marketing to attract buyers that want to buy their tiny homes (cash or 25 year financing) and live in this park, until there are 44 pads occupied by tenant-owned tiny homes, paying $750/mo lot rent, on 1 year leases.

Consider accepting the tenants if they pass your screen, deny the dog, require a certified clean bedbug report for their current home and belongings and a separate bedbug deposit to cover future treatment if needed.

These loans are structured with a combination of a first mortgage from a conventional lender (typically covering 50% of the project costs), a second mortgage from a Certified Development Company (CDC) backed by the SBA (covering 40% of the costs), and a down payment from the borrower (typically 10%).Bridge Loans: Bridge loans are short-term financing solutions used to "bridge" the gap between the purchase of a new property and the sale of an existing property or the availability of permanent financing.

I do think you can normally get funding in that time frame and it doesn't have to be actual cash for balance but I do think the deposit has to be cash, debit, certified check etc. 

Make sure to confirmwith the title agent if you need to bring certified funds or wire the funds beforehand and how far in advance the funds must be wired.
