I have relatives in England. They have bought a very large house in the country (about 4 miles from a small city), and remodelled it so it has three entirely separate homes; separate entrances, living areas, kitchens, bathrooms, etc. The house was originally built as a small hotel/conference centre.
- They (in their 50's) live in one part;
- her parents (in their late 70's) live in another part;
- the third part is occupied by their daughter, her partner, and their children.
I have no idea how they work out "rent", etc.
Would you like to live like this, or would you prefer more distance from your relatives?
