My initial advice is to hunker down.

Considering the sacrifices both of you are making to obtain Sean's advanced degree, you are to be commended for really living on a shoestring budget.

Every time a fixed-expense item is paid off, reallocate that former payment against another debt. Combined with Mrs. Brown's employment as a nurse in 2002, you will be able to stop the interest clock from ticking forever.

It's almost too late to sell now.

Get yourselves focused, build a financial base, then go for it.

Unless Sean is at ease with that course of action, it's quite an albatross for upwards of two decades.
