It's the visual thing for some people mostly, with such small wall space having it right there in your face isn't ideal. when at all possible, every flip will just get duct work and standard air conditioning. 

The local meetup ideal is always a favorite of mine.

That seems like an ideal situation if you are going to manage at a distance but it could be hard to find since managers like to do full management not all-a-cart. 

However, it’s not my ideal renting.

Ideally, I am looking to add very in depth information to ensure the lender is fully aware on how they can have "their money, make more money."

That doesn't happen to my clients as I deal with lenders who close billions per year in loans. 

You need to incorporate the type of vintage you want to buy, your ideal value-add strategy, the market and submarket, how you want to buy, etc. 

Single family homes is what drew me to OKC, it seems not ideal for multi-family to me as it seems there's a strong preference for single family homes, it's not a high density metro.

So, you would want to have a plan ideally BEFORE you buy the property if pulling cash out is part of the long term plan. 

There is no hard grading system on investment properties so “Class D” would be a subjective term but ideally it would refer to the “state/condition” of the property, “quality/affordability” of the tenant base and the “rent/income” it could provide.
