Buy a 13 acre run down old mill property which has 10 developable acres and an operating 6 unit dry storage warehouse and small 1,500 sq/ft office building. 

But look into single family long term rentals, single family short term rentals, multifamily, office, medical, retail, storage, industrial, etc.

I'm reading hundred of syndication track record including hospitability, self storage and multi-family.My problem with multifamily syndication for example, is their IRR is pretty much comparable to residential. 

Could do boat and rv storage. $20,000 in taxes.  

I will then get another stackable washer/dryer unit and create a room on the main floor, replacing a small storage closet next to the main floor bathroom.

Don't leave extra bedding out for them but have it available (like in a locked closet or storage cabinet) should it be requested.

STR's, storage units, and even something like a coffee hut can be easy to run, and not far outside the box for a REI.

The assets can vary widely, from multifamily, self storage, mobile home parks, industrial and on and on. $200k as a single earner is enough to qualify an individual as an accredited investor, with the caveat that you must have earned >200k the past 2 years and expect to this year as well.

I've already posted about the two K Mart facilities that we have purchased with the help of our investor partners, and are actively renovating and converting to Drive-In, Climate Controlled self storage, but this one is a little different, because there is finally some instant gratification! 

If it is a common area rule about storage etc  enforce it.
