One is a 60 unit b class property in Ft Worth TX. 80's build, townhouse style property in a nice old money neighborhood of town and close to a medical school.

Providence and surrounding neighborhoods don't have positive inflation-adjusted growth over the long-term (shocking) so to make money in this city you need to i) invest cyclically and ii) have access to good deal flow.

The only possible exception to this would be if you are house hacking in an A class neighborhood, and you are using a low down payment loan.

I personally find a property I am interested in and then drive by to check out the neighborhood (do people take care of their properties, are there lots of boarded up houses, etc.) . 

I had actually been looking for a quad in this neighborhood for a while so when it popped up I knew I was going to get it.

How's the neighborhood and local school system? 

Recent sales mean almost nothing when SFR’s for sale, in a neighborhood, are getting price cuts.

You have Repairs listed at 20% so if you are essentially saying vacancy and repairs are 10% each that is fine.If you're getting $1,300/mo on a place you're paying $50,000 for that is good......UNLESS it's in a D or F Neighborhood, in which case the cashflow can look great, but in reality be horrible because of constant tenant turnover and unreliable tenant activities. 

"Indoor/outdoor living" is the concept of putting in a huge sliding glass door (the size of a whole wall), for instance, that would, when open, combine a background and living room into one free flowing state.Market research indicates that renovations, and subsequently, "indoor/outdoor living", are very popular right now.For a personal perspective, would it be worth it to put these types of products in a Class B home, in a Class A or Class B neighborhood?

Of course they want the highest possible return for their money, so they look hard at marketed "C-class properties" in "working-class neighborhoods" in large cities like mine.You'll see utterly insane posts here on BP about it all the time.
