I believe they mention those things on the podcasts as a way of CYA (Cover your A**).

I know my landlord policy does not cover any sort of business operations in my rentals.

I’d like to keep it SFH because it maximized bedrooms and means tenants can cover utilities. 

However, I just want to caution you against getting into the habit of hand-waving whenever someone brings up an expense you don't have in your calculations, saying "eh, don't worry about it; I have enough cash flow to cover it."

The extra $100 per month would most likely just cover vacancy and cap ex costs so I’m still not cash flowing very well on this property.

Changes beyond the scope of their contracted dictated by the owner or governing agencies or both.Next project you do, ask the engineer to make sure that their cost covers plancheck corrections so there is an amicable understanding of what is being paid for.

You will need a lender with a deep product line that will cover virtually all your needs.

So I guess that covers the basics with some extra details and poor grammar thrown in for good measure.

As long as you are able to comfortably cover all expenses in the worst case scenario, you should be good. 

The BiggerPockets Summit, oh wait they don't have one anymore :(The Mr Landlord convention around May every year is a great one to attend that has a focus on rental properties but they still cover other aspects of REI.
