And these class-D neighborhoods only suffer in economic downturns.

I do not think however that the economics work well, you are unlikely to cover your expenses as what you can command in rent may not cover a mortgage due to high real estate costs.

I’d rather have a home in NYC or Denver that has economic fundamentals to appreciate massively.

Economic and demographic trends, Look for markets with growing populations and jobs, modern industries and diverse economies.

Long story short, I'm in the middle of reading his book Big Debt Crisis at the moment.

Many people forget that as little as 6 months to a year after the Great Recession, housing crisis, whatever you want to call it, people were already calling for another one.

Not only does the house have lots of cash flow potential, it's located in a market experiencing historically low vacancy rates, and what's being described as a "rental crisis".

Some would argue economic of scale, I do agree to some degree, but we do have sfr from far away that we make great cash flow without being there and those are some of our initial investments.

There is nothing wrong with 9.45% ROI in my opinion especially in this part of the economic market cycle but just be sure your DSCR is high enough to weather any corrections in your particular market.  

@Steve Vaughan Respectfully, throwing "millennials" into a category of people who had no responsibilities and thus not impacted by the financial crisis is short sighted.
