To keep costs down, I have suggested living in a small condo, perhaps one bedroom and about 600sf — even if you might have a family of five. But, it should be a nice place, in a decent neighborhood. Here is a real-life example of a condo in Miami, which I take as a place which is not very cheap (Detroit) and not very expensive (San Francisco). It is listed right now for $69,900.
This looks like a nice place for children, and also, you don’t have to take care of it.
The living room.
Yes, it would be nice to have a big $700,000 detached house. But, it would also be nice not to have to pay for that. Take the financial load off.
