This is a loan, not an investment - the difference should be obvious, but to spell it out: they'll want their money back whether you make it or not.

I'm going to make an assumption that they are looking for equity too, but I could be wrong.

Putting it together: they loan you money which you have to pay back with interest, and you give them a %age of whatever you build just as a topping.

You could go to the bank and get about the same and not have to give away anything. Is this really what you want?
