I do not plan on buying another investment property, just maximizing and concentrating on this one.Would love to hear your input and ideas!

Concentrate on purchase price unless you've maxed out your conventional mortgages.

The student rental areas are really concentrated around the university and everyone knows what they are, both student renters and landlord owners.  

Otherwise, there's a major concentration on the up-sell, especially during the second half of the boot-camp. 

Currently it is virtually impossible to permit a treatment plant that converts sea water to potable water because there is no viable (read permitable) means to dispose of the highly concentrated waste water.

It is easier to reach a critical mass where you can start getting better bids on services, and if you want to start turning management to a professional manager so that you can concentrate on getting more deals, you will get better pricing there, too.  

Yes, there are loan concentrations a bank has but it's not necessarily the number of notes you signed, it's the amount of loan concentrations to one borrower.

If I had to sum it all up, 2015 will be a year of concentrated focus in this one area of business. 

Real Estate by its nature will be more concentrated than stock investing.However I think the concept of putting a similar amount of money into Real Estate each year/every 6 months is probably a good one. 

One of the primary reasons for doing this is to open up my head space so I can concentrate more on myself & my well being rather than focusing on my patient's condition, charting, billing & coding.
