Me and my partner are looking for a house in zone 3-4 right now, and I can tell you that every single home we've looked at is on for an asking price (and they're selling) of between 50-100% more than they last sold for 5 years ago.
We looked at a home that sold for £415K in 2017 for example and we were outbid. It went for 865K
Flats aren't so hot, that's for sure, but there's been masses of price growth over the last 5 years on houses. There's a stunning lack of stock on the market.
