The turn key property is on a tiny island in the Chesapeake Bay in Maryland called Smith Island.

Purchase price: $142,500 Cash invested: $25,000 We purchased 2 adjacent, tiny rowhomes in the Northern Liberties neighborhood of Philadelphia.

Do not consider commuter colleges or tiny ones. 

Would you suggest subdividing the property, building a single house, or building multiple cottages/ tiny homes?

The properties are often flawed and no well-suited for a family to live there long term (lot's of bedrooms, but tiny living room, no yard, no garage etc), that's why they sold for a discount an get used as STR.

While I've never invested personally in Detroit, my usual word of caution to investors in these "lower cost" markets is that while cashflow is great on a % basis, make sure to look at the actual quantity of cashflow. 

Just have to stomach the higher rates for 2-3 years, break even (ideally cash-flow a tiny bit), and handle the PM during the roller coaster ride our President is putting everyone on.

We will turn into a tiny house village. 

The tiny town the land is in won't let you build with less than 10 acres.

I've seen my investor clients keep text campaigns pretty targeted as they prefer quality over quantity.
