Experience is the best teacher.

Any instructor can talk faster than they type (may have a voice activated system, that might make a difference) but the amount of information the teacher can put out will be limited compared to being in a classroom.The same applies to the students in asking questions, they may not even ask more involved situations due to the limited means to communicate.Even if it's an open chat, all being present, there are limitations in providing a more in depth discussion that you can have in person.

As a former teacher, I am very aware of this.

It reminded me of the following.....I do work with schools teaching their teachers about brain development and showing them simple exercises kids can do that are only games but they actually increase IQ.This is all supported by brain research using real time MRI's to actually watch stuff thought occurs in the brain.Anybody old enough to remember those creepy films we saw in school about psychologists putting wires in monkeys' brains and then doing things like blowing smoke in their faces?

As I previously stated I was formerly a teacher and in this field it has usually been a female dominated sector especially for younger grades like elementary, this isn't due to the fact that females are better at teaching children because this certainly isn't the case its just a fact that more women occupy the field.

We encourage our students to look for neighborhoods where people like cops, firefighters, plumbers, electricians, teachers, secretaries, and other blue collar or not-so-well-paid white collar workers live. 

My family had to cancel Spring Vacation trip ( Wife is a Teacher) at some monetary loss to accomedate the beginning of this project.  

Buy or inherit and hold all their lives while working the properties for income.I've seen teachers, firemen, software engineers and all sorts of people utilize both strategies successfully.

I'm a teacher/freelance writer and he's a doctor (Chinese doctors are NOT well paid like their American counterparts!

Great to take the plunge there is not better teacher than the mistakes you will inevitably make and come back stronger from on the first properties.
