Well, what do the numbers crunch out to be? Do you love the house? What would your house payment be if you refinanced? Would you qualify for a higher mortgage payment? How much would a boarder bring in? Do you get along with roommates? How long is your time horizon? Would you be okay if you had to stay in the house for 8 years before it recovered its' value? Could you get a part-time job to help with making the payments? Woulde you want to live in that house with a new wife, given all the memories of your marriage?
Look at the numbers, this is a business question as much as anything.
