In my case, I have residential rentals in one LLC, commercial properties in another, self storage in a third, and my real estate company operates in a fourth.

You might want to look into multi-family, self-storage, or even mobile home park syndication. 

@Mo KarimThere are two types of cost segregation companies that investors can go to.Engineered Cost Segregation studiesDIY Cost Segregation studiesCost segregation studies normally make more sense if the property has a higher cost or a unique asset class(mobile home park, storage, etc).

Self Storage- LLC Operating Agreement (biggerpockets.com)

The Units have a small pantry/storage room that could house the furnace.

Good evening guys - anyone on here monetizing vacant land with RV storage / truck parking? 

Hey BP Community,Does anyone have any experience dealing with mice in self storage?

Hard wired systems that have a localized storage will work without paying for wifi but you wont be able to see whats going on unless you go to the property and check the recordings.

Dishwashers, if tenants never use them for anything but storage, will need to be replaced, but otherwise, aside from clearing the drain line occasionally, last longer than other appliances.

You might also look at any kind of syndications like apartments, self storage, NNN funds, MHP, etc, to see if that would help you with your strategy.
