What do you mean by creative financing? 

Did you do this deal or was it one of your clients? 

I don't think I'll have the time to find something used since I'm doing most of this remotely. 

Be candid and do it in person.

Neighborhood Scout is not going to cover any shortfall you have if it doesn't materialize.you could try finding a bank or broker that will do 80% out on a refi, although probably not possible to close by the end of this month. 

Where do I even start?

The broker/owner, team lead, or seasoned agent could help another agent that is new in the business just like I did when I got into the business, I got a mentor to help me through gaining market share and how to do it.

Contractors do a great job where they know you're going to look.

Have you thought of doing Seller Finance?!  

Quote from @Taylor Dasch: You either have to leave money in the deal, find a lender who will do a higher LTV, or flip and cash out.
