For the past eleven years, I've been a high school science teacher, but because of the ever increasing demands in that career, I decided to switch.

I suppose Building Science is not a subject of much discussion on this platform...

I have heard the renters may not be as reliable there ... not sure if that is fact or fiction.

Work through your learning and problem solving TOGETHER, in a methodical manner:what's the problem to be solved (and each should not be compounded with extra conditions).list all possible solutions you can find (without discarding any due to bias, personal business ideas or obvious negative effects).then find and list all pro+con issues related to that solution you can.SAVE your work in a binder for quick access later and to visibly demonstrate just how far you both have come.There's no rocket science in REI, but limited exposure to business concepts, contracts, accounting, marketing can ALL be overcome and your partnership will grow as a result.

It's an art and a science

It will have a big impact on your cash flow and profits.Real estate investing has a lot of variables to consider with every investment, but it really isn't rocket science. 

Or do we want to build a society where people who will advance society (technology, medicine, science) will thrive optimally?

We are not talking about rocket science, Steve. 

Note that I said cap rate range because it's not an exact science and there are a number of factors that can influence this. 

Well, I guess around you I can't say I have a degree in rocket science, since yours really is.
