just for reference about my amassed 'wealth', the combined cost of my mortgages is less than a studio apartment's rent in the bay area. i left the west coast for precisely this reason
Are the properties underwater on the mortgage?
Can you rent out the vacant units?
It seems like getting those two sorted would greatly improve your monthly situation.
going back to the wealth thing, I recommend you think of these places as assets, not set in stone. If you are ahead on your mortgage, they literally are, slow to sell but worth real cash.
