Rising rates will make it more difficult to own, which will increase demand for rentals and thereby enable me to raise my rates, resulting in increased income on my properties.  

They've enabled us to go completely paperless.

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 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.

Both, my wife and I have a comfortable 6-figure income as well as savings stacked away, which enables us to “swing” the rent.
