I suggest you both get out & do a couple of longer trip & THEN go back & consider your renovating options.
I know once we ventured out & went back we quickly gave up the idea of throwing money away.
Firstly what you consider improvement might quickly be removed by any new owner.
Secondly at 70 do you really have enough time left to really enjoy traveling?
Leaving it too late is a very common mistake.
Can you spend most of your 'assets' before you die?
Remember that once a hip or two goes & other aged symptoms set in you really won't spend that much.
We all would like to live for ever but it just isn't going to happen!
Oh! Good luck with that "next 70" lol
