When my wife died, I was face with much the same situation. I was living in Ohio and all my children and other family members were living in Tennessee. I recognize that if I got sick with cancer (like my wife) it would be a major problem for the children. They could not take a leave of absence to take care of me since they all had good jobs, and if I died unexpected, they would have problems disposing of the house and all the stuff I had collected over a number of years.
My solution was to pretend I had died. The important pieces of furniture that I wanted to remain in the family I gave to my children the other items which had no sentimental value I sold or gave to goodwill. I sold the house and started full time in an RV. Since then, I have travel in all the states and from Newfoundland to Alaska it was the best decision I ever made.
I’ve told the children if I get sick at some distance from Tennessee, I will drive the RV to my son’s house and park in the backyard for my last few weeks. If I die unexpectedly simply cremate my body and give the RV to goodwill or the Salvation Army.
