Be 35. At 25 bought a positive cash flow rental property (duplex) instead of getting married and buying a money pit house full of money pit kids. Low interest rates made the "ARM" mortgage cheap for several years, but now rates are on the rise!

Just locked in a new low rate fixed mortgage that can be paid off in full in 5 years if I raise rents 3% a year and rent the units for 11 months per year (55 of 60 months).

I'll retire at 40 to one side of the duplex, and live off the rent from the other side and my savings. or rent both sides and liver where ever I want.

No wife, happy life!
