They are trying to prevent investors/brother in laws from "stealing one".

Tenants typically handle smaller things like changing fridge filters or furnace air filters.

just really disappointing that the loan officer knew we wanted to rent it out and when the real estate savvy guy wasn't there, made the other buyer sign something preventing that. 

I am really just looking to avoid the worst of the worst areas (anywhere with open air drug markets or active gang warfare / prolific violent crimes).

I hear people talking about air flow etc.

If the tenants leave cereal boxes out and the house gets overrun with ants, it's still your responsibility as the landlord to have pest control in place to prevent or treat the problem.

Make sure you understand the basic math, what qualifies as a good investment, how to manage your investment and prevent losses, etc.I would start with Set For Life by Scott Trench.

(I just went through probate when my mom passed and it sucks and would like to prevent my successors from having to deal with the same if possible).Bonus question, one of my properties is still under mortgage, he mentioned something about transferring it to an LLC can trigger a due-on-sale clause but not when transferred to a Trust.

Otherwise, you could also provide prevention recommendations somewhere on the lease that includes what you've mentioned above.Assuming you don't have a lawyer to help with your rental agreement you can find some sample clauses on a site such as Law Insider.

That calculation is so simplified that it doesn't even bother to factor into the equation any costs  and that $200K just magically appears out of thin air.
