What documents do I need to put our rehab money in project

[Sanjay Gupta]

Hi,

We want to put rehab money to fixup property which is owned by owner ( not us). We will put  our rehab money and fixup property. So what documents do we need so that we get our money back when property gets sold?

Rehab money is not fixed e.g. it could range from 100K to 120K

We have base price of property and then profit would be split 50 % to owner and 50% to us after taking out all expenses.

Do I need o hire attorney to draft these documents ?

Thanks a lot for your help.
