<prompt> Human: Throwaway because my friends know my main account username. A good friend of mine is planning on purchasing a place with his girlfriend. He has very good income but bad credit; she has good credit but very little income. They want to combine their resources to get approval for a house. The way he explains it to me is that their names will both be on the title to the house, but only her name will be on the mortgage. Up until very recently, the two were planning on getting married. However, now some cracks have developed in the relationship and the possibility of separation has been raised. My friend has also explained that in the event of separation, his GF agreed to move out of the house if he would handle the entire mortgage. He still wants to move forward with the house with the intention of paying the whole mortgage if that occurs, because he thinks its a good investment and he likes the place. Lets assume that in the event of separation, she will willingly move out and my friend will start paying the entire mortgage. Im fairly certain this is still a bad idea even if the house does appreciate, but Im trying to compile a list of reasons why. As you can surmise, hes a bit headstrong sometimes but is open to listening to a well-reasoned argument. Thanks!  <response>: The way this is set up, shes the one who should be running away from this deal. With only her name on the mortgage, there is nothing stopping him from defaulting, and completely ruining her credit. That might be a moot point though, since the odds of her qualifying for the mortgage with very low income are not very good.
