What to look out for in non-conventional residential real estate?

[Amol Kulkarni]

While browsing listing at some of the websites, I came across Self Storage units, Campgrounds, RV Parks and Mobile Home Parks.

Some of these seem to be pretty reasonably priced compared to multi family rentals. I'm wondering, though, what would be the catch in each of these, especially for OOS investments? 

Many of these are in rural areas/small towns where I guess it would be difficult to find property management. What would the other potential pitfalls be? Any insights or advice would be appreciated!
