<prompt> Human: Im having flashbacks to college when my business law professor emphasized never to cosign on a loan, but here I am.Per my parents divorce, my mom is supposed to receive several thousand in alimony and another several thousand in child support and spousal support.My dad has chosen to go deep into arrears for his obligations. Even when he does make the rare mortgage payment he is obligated to make, the entire alimony payment is put toward a mortgage at almost 7 percent. Alas, she is not getting a lot of equity out of the house. This makes me think she should downsize to a smaller house so she can pool the rare payments from my dad and save it instead of throwing the payments away into a black hole of a mortgage. Not to mention the mortgage is regularly several months behind and is threatened with foreclosure.After paying the existing mortgage, she would likely see around 200k before closing costs and realtor fees. Her credit is shot from the divorce and she lives in a very high real estate market. She wants to stay in town for my little sister for school. To make a long story short, a two bedroom condo goes for around 250k. Im considering cosigning on the mortgage while renting an apartment of my own. My income at that time will be 60k with limited debt and a mid 700s credit score.I was thinking about cosigning and having a contract drawn up that would grant me sole ownership of the house should it go into default. In a perfect world, one in which my dad pays what he owes my mom, she could save some serious money. But thats a big if. I rambled on but I think Ive laid out the majority of my thoughts. Any suggestions as to the smart move here?  <response>: Should you do it?Short answer: NoLong answer: Nooo.
