Heh. I'm sitting in a timeshare right now. My parents bought it at over 30 years ago, and had a good time trading all over the country, but that is no longer as cheap and easy as it once was. Right now, yearly maintenance is about $400/year, for a week right on a North Carolina beach in a unit that sleeps 6 (not particularly comfortably).
There was a special assessment a few years ago, spread out over 3 years, that amounted to about $1000 when they refurbished all the units.
Dad died years ago. Mom's in her 80's. The place is okay, but she'd still rather sell. Not that she can.
I have heard of disclaiming an inheritance. Unfortunately, all that does is send it on to the next beneficiary, but there are no others. Then what?
