Mobile homes are non-permanent buildings that typically fall into 5 year personal property life.

.- Last November, while researching the parking industry, I came across a non-profit organization called Veterans in Parking (ViP).

If they're public, look at their stock prices, look at their income. 

They include: zoning requirements, building codes, impact fees, permitting requirements, design standards, public land requirements, and federal Occupational Safety and Health Administration regulations and other labor requirements.

Cap rates Here is the link for non-owner occupied property tax cap rate Is 8%

So maybe just publicize it on FB market place 

I've seen some simple templates circulating the internet and this is nothing alike.

And also, what about buying in an area that allows for non-owner occupied STRs, so you can Airbnb or short-term rent the place when you move out?

There are always non-warranable condo options depending on the exact situation. 

I remember listening to a podcast episode of someone who would rent their LTRs to a non-profit at market value so they could use the housing for people in need.
