Creative ways to come up with down payment

[James Green]

Hi all, I'm going to get straight to the point. 

I am looking at purchasing a commercial property in Florida, and everything is straightened away financially with owner financing for 85% of the purchase price. The numbers have been ran over and over again and this property keeps showing easy profits. However, I don't have the money for the down payment, and I don't have the collateral to get a loan for the remaining amount (of $150,000). Are there any resources (other than credit cards) I can get financing from based on what the property will bring in or places I can find a (short term) partner for the property? 

(This property is about 10 miles from a plot of land of 55k acres Disney is looking to purchase, but that isn't widely known and property values haven't risen accordingly because nothing is a done deal.) 

I appreciate the advice!
