Hear me out, I'm not planning on using a friend or relatives address to try and steal a place at an oversubscribed school or anything. But I'm in the process of buying a house. I've read all the official info and know that I can change address officially after the January deadline until the end of Feb. But I'd then have to provide hard copy proof of new address. We're in a chain and with Covid delays I'm really worried exchange will wind up being early March or later. I'm wondering about seeing how far along in the buying process we are by the initial January deadline and applying from what will be our new address if everything is close to exchange by then. I know this is against official advise, but... Has anyone done this?
