I live in a bungalow and the only time they come on the market is when someone dies. Every single one has been bought and then made into a house!I downsized. Effectively buying a smaller house in a better area so there was no large cash pot left over.
The bottleneck for downsizing seems to be lack of bungalows. They fetch silly high prices because developers stopped building new bungalows. Meanwhile, the demand for older 4 and 5 bedroom family houses with big gardens is strong. Prices are still going up. It's a safer asset class from an investment perspective. If or when interest rates are lowered, house price inflation will surely go up. At the same time the alternative "equity release" will become more attractive as an option. Maybe equity release could fuel MH sales.
