Managing properties and flipping houses sounds like cake, but take a look at the hours that people who do this for a living put in, and I'm not so sure how appealing it will be.
Granted, there are many opportunites, but who the hell wants to deal with 10 tenants, collecting the bills, evicting the bastards, and paying all the bills? On top of a 40+ hr work week?
My "uncle in law" does it and has about 20 houses in his portfolio....2/3 are his and the other 1/3 are properties he maintains for others...it's alot of work...and you HAVE to have a knack for it...I just don't picture many by the book...book smart...yet not so street smart pharmacists doing well in this arena.
