I have more than one property, NJ, and have certainly benefited from it. Many people in the UK have more than one property, thanks in part to the availability of buy-to-let mortgages, though I have never had one of those. However, many people who only have one property have gained a lot at the expense of today’s youngsters.
A typical example of what has happened over the last forty years or so:
A couple buy a house thinking that it should be a safe investment as well as a home. However they soon find that, due to housing shortages etc, prices start to go through the roof (pun intended), and they realise that the house won’t just hold its relative value but will be worth around five times its relative value on their retirement. They decide to ‘release a bit of equity’ to buy a new car and fund the long-haul holiday they have always dreamed of. They then sell the property on retirement, downsize as they always intended to do anyway, but have a much bigger pot than they envisaged to top up their state pension. So where did all the money come from? Of course it came from the youngster who had to pay five times the price for the house, so the youngster funded their new car, holiday and their extra pension. Now it happens that they have two youngsters themselves so you might think they would be a bit embarrassed about all this, but no not at all because they can just blame government policy.
