I bought a house in California with my boyfriend just over a year ago. We're splitting. He put up his car as collateral on a 17k loan for a down payment on the home. He now doesn't have a job because he got fired, and according to him if we split I owe him $10k... I MAY be able to afford the mortgage on my own if I can refinance and get a lower payment perhaps? What do I do? What are my options?
