<prompt> Human: So here is the deal, my mom owes 155k on her home valued at 401k. The house features a legal one bedroom downstairs suite. She is getting sick of taking care of the house she let fall into a state of disrepair. Most houses on our block are valued 80k-120k more than hers even though she has the largest yardonly legal downstairs suite. She also rents out the spare roomsdownstairs suite for way less than the average price for our city, which reflects the state of the house. Shortly, my Girlfriend and I will be moving in downstairs and will be adding our names to her mortgage to take over and be responsible for the payments and fixing up the house in exchange for 40ish of the value of the home. We are having a Notary draft up an agreement between the three of us and Im including details for our agreement below. What Im wondering is if any of you have any ideas warnings things that I should have included in the agreement. -For payments such as the Property Tax, she will be responsible for 60 of the payment, we will be responsible for 40. -for rent collection, we will collect 40 of the rent, she will collect 60-Im also making her agree to contribute to a Maintenance Fund every month that we will be adding to as well to cover the costs of fixing everything up.-if we sell the house, she will collect 60, we will collect 40 and then subtract the principal amount of the remaining mortgage for our side. So the plan is we will move in downstairs, fix it all up and either live there while playing it off, move out and rent it, or sell. Side note: My credit is around 680 and my girlfriend is in the 830ish range, we have 10k to put down and cant get a mortgage large enough to buy even the cheapest condos or even get financing for a trailer in a trailer park, so this is really the only way we are going to get equity unless we quit our careers and try to find new jobs in a cheaper city.  <response>: I wouldnt buy anything with your girlfriend.
