Live In A $100,000 Home Without Money
The best way to live in a $100,000 home without money is to become a "house-sitter."
You offer to live in luxury homes while the owners are away vacationing.
If you live in a large city, you can probably live all year rent free by keeping a notebook of clients who need your services to protect their homes from vandals while they are away.
If necessary, get yourself bonded.
