Yes, you can have a contract with your boyfriend providing virtually whatever you want - that you are to receive a certain percentage of the profits from any sale, that you have a right to live there rent free until sale, that you are giving your boyfriend this money as a loan which he must repay with interest, and the loan will be secured by a security interest in the new home, etc. Just be sure that the contract that you agree to meets all the legal requirements of your state. I don't know exactly what these would be, but for starters you should make sure that the contract is in writing, and that each of you sign and have your signatures notarized. There may be additional requirements depending on the exact agreement you make, so make sure that you understand and comply with all the necessary formalities.
