My grandparents were fairly well-to-do but they couldn't afford to live there now.
Our family party was held in a house belonging to the Methodist church which was probably purchased new because no church would be able to justify buying it today- even if it had the money. An identical house across the road is on the market for £2.3 million. And what do you get for that- a mansion? No, just a decent but unexceptional mock-Tudor detached house- on a narrow plot- with a small garden at the back- the sort of house that went up in its hundreds of thousands in the years between the wars, a starter home for a city clerk. There's no garage so you have to park your Merc on the street.
London prices are mad.
