Intentions are one thing, practicalities are not. My mother is determined to stay in her home (bought only after they both retired, they'd rented until then). But my father didn't have much choice.
Re what's left over. Well, yes. But what's the alternative? Presumably, spend it all then throw yourself onto the State?
I don't anticipate being here until I die (not that I have total control over when that is). There needs to be enough in it to at least fund some care if needed for me and/or Filly.
What would you be happy with? As I said, that comparison was because you post about buying them and their appreciating value. At least rented property would be some use along the way.
It could be argued that some homes are luxury items. (Ours isn't It's nice, comfortable, we use all of it, but not luxurious).
