What I would NOT do is refinance the property you have, thereby destroying the cash flow you have.I'm with you and can't see myself ever playing with the 30-40+ rentals it would take to replace my salary, but that is a really tempting thought to be self employed managing my own properties, and not sitting here on a Sunday afternoon realizing that Monday morning is just around the corner!

There are tenants out there that would absolutely destroy your rental in retaliation.
