LoL awww I understand, I'd be gutted if my parents decided to downsize or sell up and move over to where I am (they won't though, and my sister who inherits our family home will be rattling around there by herself probably when the time comes).
Is it also too expensive to rent from her?
Unfortunately yeah, since we're still paying off our own house, hopefully we'll have it paid off in the next eighteen months, but until then our hands are tied.
Ahh I didn't realise you were paying off your own house too, yeh that would definitely make it harder :<
