Today tipped the scales. 

If you can successfully navigate the initial small scale deal, attain results consistent with your overall investing goals, and still want to invest in real estate ( you mentioned in your bio other recent business ventures weren't right for you) then you can always move up to multi -family or commercial properties.Best of luck,Josh

Looking to get serious and scale up with 2-3 properties over the next 12 months or so.I wanted to introduce myself and thank everyone for the pool of knowledge here at BP!

I went from 4 units to 28 in about 2.5 years while making $14/hr in a factory. http://www.biggerpockets.com/forums/311/topics/125040-how-do-you-scale-your-business-so-quick

You'll def need to get rid of doing things yourself to scale it past 6 a year or so. 

Here's another method though that works on a much larger scale.  

Hi Roger,Yes, here in Milwaukee, things seem to be going well for the various people I know currently in the landlording biz, including myself (in a small scale as of now) As Nathan mentioned, here on BP Milwaukee has been getting a fair amount of attention lately, or even for a while now but I'd agree that there are probably a number of various mid sized metro areas that can be good places, or certainly in our current market conditions, which seem to be a very good time frame now for owning residential rental units. 

We would also like being able to scale into larger properties.

IMO, it takes a certain personality type to be effective as a property manager on a larger scale.

Just a matter of scale.
