Writing out a contract for splitting couples

[Joe Lujan]

Good afternoon all!

Here it is!

My daughter and her boyfriend of 3yrs are splitting up. They bought a house together. My daughter put down $30,000 all together with her own money for down payment and closing costs. He didn't put any money in. Neither on can qualify on their own to refi and buy the other out. His mother said she will help him keep the house since he refuses to leave. His mother will give my daughter $15,000 now and she is to sign a quit claim over to remove herself from title. Of course, Her name will be on the loan. Another $5,000 in 2024 and another $5,000 in 2025. total of $25,000. Which I think is stretching this ordeal too long. 

Numbers: Sold price: $520,000. House comps at about $545,000 so about $25,000 in equity. selling the house will short change her drastically.  I need suggestions on a FAIR contract that my daughter can present to her EX, that will work for both. 

All suggestions will be taken with great thanks!!
