I don't really qualify for this thread as I am married, but I think I would sell if anything happened to my husband. I HATE yard work and I know very little about repairs. Taxes and insurance on our house run $375 a month, so in our tiny town I could rent a small house without upping the budget much. It would be a downsize, but if I were alone a downsize would be good.
I guess you just have to decide if the hassle of home ownership outweighs the positives. There are positives.
