Great thread, I thoroughly enjoyed it and can relate as I can be extremely lazy (after all why do you think I love passive income so much!! :)
Starting to build your Real Estate empire when you are young and not tied down to anything or anyone is HUGE IMO. I started at 22 with a 4 family (I was single living at home) and am almost 45 and hopefully closing on my 16th rental (28 doors) I self manage, am married with 2 kids work a full time job as a Sys Admin in NYC and have over an hour commute each way to work from NJ! OK maybe I am not so lazy after all :)
Back to my point as you get older, get married have kids things get harder to do, more expenses, kids, 529 plans, 401k savings Etc... Best advice I can give is get started young so that you have time on your side and can work in your favor.
While it is never too late to get started in Real Estate starting younger really can give you a big advantage!
You can do anything if you want it bad enough and put your mind to it!
