Need advice on funding property purchase

[Amy Atnip]

I am a new licensed GC with no new builds under my belt yet. We flipped a house last year with decent profit. We have come across some property (house and 5 acres) that could easily be surveyed out into the house plus four building lots for spec homes. The plan would be to immediately sell off the existing house and then build four more. My problem is that I don't have the down payment for the conventional loan. What are my other options for purchasing this property if any?
