I'd sell. You're on Odessa road aren't you? Stow brothers have agreed a sale this week on Chichester rd fully done and extended but no side return and I'm told it's very close to the 750 sticker price. Seems nuts to me. I sold mine for 702 18 months ago when the market was red hot.
We're renting when we first move so essentially chain free, good to know things can move quickly with the right buyer.
