@Marci Wilson There ways of structuring the deal are endless.
One that I've done in the past and both I and the investor liked is this: Borrow the purchase price and if willing the rehab money as well, up to say 80% ARV at 8% interest. Then when the home sells offer a 10% profit as well. I did this to get started because I didn't have my own capital for the rehab and wanted to entice my buddy to do the deal with me. Take these numbers and change them or leave them the same. The key here is to make it a win-win and if you are just starting out doing several deals will give you a wonderful "education"...may not make lots of money but you will learn how to do it better in the future so that you can make money.
The other thing to explain to a possible investor is what the 8% really looks like is something like 16% annually. If you borrow the money at 8% for only six months then they could put that some money back to work with you for another six months and get another 8%.
Good luck
