We moved in our early 60s to our present home, having previously downsized too quickly without enough thought, to a small detached on an estate in a location which we didn’t like and to a house which proved just too small.
We then rented for a year and chose more wisely. We are now settled in a new build, not on an estate, on a quiet no through road, with nice neighbours.
The most important things, after our initial mistake was location, location. Safe established area, near bus route, shops, pharmacy and doctors all within walking distance.
A modern house means there is easy maintenance, warm with good insulation, small gardens. Four small bedrooms, inbuilt wardrobes, 3 showers/WCs (1 en-suite 1 downstairs). It is detached, no neighbour noise is important to us.
The compromises are, the stairs, which could be a problem in the future, but we would fit a stair lift. Lack of a garage for storage, but have plenty of driveway parking. Downsizing “stuff” is very liberating, most of us have too much and we didn’t miss things put into storage. There are always some compromises when you move, but can be an expensive mistake if not thought through carefully. Best of luck.
