I've previously made errors in investing and I do not want to repeat...so I'm hoping to get some input prior to going back in :-)  I have a fulltime job and a part time psychotherapy practice.My longer term goal is to make 5k per month for retirement.My medium term goal is to quit my job and do part time work. in order to to that, I have to pay back the $ I borrowed from by retirement fund or I have to pay major taxes.

We would probably need to borrow another 10K or so, maybe from a relative for the next FHA downpayment.
