Hello,
The best approach in funding is using "On-Map" sale method. This means establishing your real-estate development firm, and promoting sale on "Pre-buy" basis. This way funding comes through costumers. minimal loan might be required for promoting needs.
Loan requests can be established through CPA firms.

Another method is utilizing major development companies on partnership basis, yet I wouldn't recommend it as most of sale profit wouldn't be yours.

happy to discuss further in details any required details.
