Lets say, two bedrooms, one bathroom and a small garden or similar, how many acres does that take up on average?
that would be best on about a 1/2 or 3/4 of an acre.
The average subdivision lot is less than one quarter of an acre, even with large homes on them. Depending on your definition of a small garden, a 2B/1B home would leave plenty of room in the yard for a home garden.
