That's very useful to know @littlejackhorner This: I had resigned myself to having to sell the house pronto, and that's partly the reason I've been in a bit of a panic! That's good to know. Every bit's going to help. Thank you so much for this. Yes, it's getting everything sorted! I'm surrounded by notes to myself to remember to do this, and remember to do that etc (bit like teaching used to be...) and it all seems overwhelming! You've set my mind at rest considerably.
