I want to be a full time investor as soon as possible, but am fully aware this is not a business that happens over night.

He said "that game is full of sharks and you will get crushed - forget about it"  Well I figured why couldn't I learn to be a  shark?

The duplex needed a roof and full electrical rewiring among other things.I let the renter stay for free for the first year and he and I rehabbed the duplex.

Amazingly I've been able to travel the US and the world while holding a full-time job.

I also work full time. 

less than 24 months most 5% banks won't talk to you, you can work with a mortgage bank and get about 7%. depending on the appraisal value and putting down 30% you will be ok for a refinance but having them appraise for 30% more to take out the full OPM may prove difficult. 

:)  I also read your profile, great job from moving from an engineer to a full time investor, love it! 

that's rare, but it suggests a lot of things about your building...like the condition, assessed valuation, upside potential, etc...I've personally never seen a 6-unit in a good area with taxes that low...Overall, I think your returns look really low, so I would say this is a relative investment...if it's in great condition in a great area, maybe it makes sense...hard to tell much more without the full property information...

Being an over achiever that wasn't good enough for me to only earn income for one source so I decided to talk with my wife about keeping my business going and working another full time job.
