Actually by the time you get done with that exercise your accountant will be free - fried but free :) to give you a good specific answer.

I have been attending almost every local "meetup, seminar or networking" event that I can physically get myself to. 

Resolve disputes and issues with the physical plant and grounds. 

There are a lot of options for remote management of a facility, but if you can't physically get there every couple weeks at minimum, you may want management and would have obviously have to figure out at what number of units that would work.Any other questions?

Investing in real estate is far from passive, you are not going to escape have to put in many long hours although the work is obviously far less physical than farming it can be high stress.

., as opposed to a physical notebook that would get messy after awhile.  

As permanent as the apartment building; physically merged into it.

Eviction does not just remove a person from a unit physically: it is the legal process for the LL to terminate the lease via the courts and recover full possession of the property. 

Even general growth direction such as 10-20 years ago knowing Collin county areas such as Frisco, Colony, Plano, etc.. north of Dallas would grow so much knowing all the planned developments of Dallas cowboys and Toyotas of the world, or does this type of stuff happen so quick relatively that you can't research with public records/websites until you starting physically seeing the development and having to make a judgement call at that point?

Considering their analysts have not physically inspected the property in person and going by what they can see they are making fairly good predictions.
