When I die, everything I have should be used for the benefit of family who are alive. Sell the property if you must. Invest in your education, start a business, lock money in the money market. Live well.
I don't see how burying me in the house I built serves me when I'm dead or serves my family who are alive. I will not use my death to punish the living by reducing the value of the house I built, in the name of "bury me in my house." There are good cemetery all around. Bury me with the dead. I have lived my life, live your own life.
Live well and pass it on to the next generation. If my wife wants the kids and grand kids to be visiting her there, good. If she sells it, fine. If she passes it down to the kids, fine. If the kids sell it, fine too.
The only thing that concerns me after death is REST.
