@Kai Van Leuven it will fail when homelessness is the cool/trendy thing in society.

This market trend is no different than the others.

Trendy areas come and go if it is just based on a few hip bars and restaurants. 

The correct way to calculate and analyze the trend is by creating dot plot chart PSF for the same configuration house/zip code.

As @Mason Hickman mentioned, they're glorified, trendy trailers in the eyes of a lender.

Everything is trendy, new, high quality, and expensive. 

They are around trendy areas like Austin, Waco and Houston.

If the shower surround happens to be a trendy size and in good shape, consider having it painted (by a quality provider) instead of ripping it out and tiling. 

@Isaac Wall Ohio City is a trendy transitioning area in West Cleveland...on the lake...very walkable with breweries and restaurants...lots of redevelopment...there is a path of progress and still plenty of room for improvement...I'm sure some of the local experts will tune in...from what I could tell last time up that way, RE prices were starting to tick up quickly...There also appears to be a lot of opportunity with vacant or blighted properties and especially mid sized MF properties...

Airbnb rates are down on average nationwide due to increased supply of airbnb rentals, this trend is showing signs of changing though as more owners switch towards LTR again.
