My condolences to you and your family at the loss of your father.

Normally being the overly responsible one in my family I would tell you to stay and take advantage of the free rent and ability to not get into more debt.
That's my conservative, responsible, not wanting to pay a dime in interest to anyone side.

Get out and live. I mean obviously you don't want to get into a great deal of debt, but if you were doing it before without creating a lot of debt, then you can do it again. Your only young and going to college and beginning life on your own one time. Make the best of it.
