Diversification is for passive investments and concentration is more appropriate for active investments.

Striving to be an Architect//Developer//InvestorI am considering applying for grad school in the concentration of real estate development.

When you look at plans in sections, you will find some key areas where costs are concentrated.

Any thoughts or suggestions on which of the above places to concentrate on in terms of rentability, ROI etc...

@Jeff Garrett   By all means, concentrate on inside the Loop if you would like to buy properties where there is no hope of seeing any cash flow.

Hi Stevel, I am a Mortgage consultant concentrated in Residential and all types of mortgages.

It is important to develop the proper team members and it is also wise to get on a plane and check out the areas for yourself (after you set up your team) Then meet your team face to face and inspect the areas of interest to narrow your search down to specific neighborhoods.I have a full team in place there, and most of my concentration has been in the Fort Worth area and west of that.

@Daniel GuerraOk,  I have only been concentrating on small multi (2 - 4 unit) and small apartment (5 - 20 units).  

Robert Young you say your setup out of Brooklyn do you have a specific area of concentration?

If you are going to college then concentrate on doing that well before you start a new distraction with wholesaling...what you might consider is if you are moving to be near campus that you could househack a house and get some college roommates to pay the mortgage for you so you are living virtually rent free while going to school.
