I would love to keep all the properties completely separate, but I just don't see how it's feasible. 

As mentioned, I would leave it and use that as a storage closet.

Depending on demand in your area that should be feasible.

In many jurisdictions any lease 24 months and longer basically conveys additional rights and a simple eviction is no longer feasible. 

Maybe city is getting ready to go crazy on solar and needs a spot for a battery storage area. 

Great property, perfect setup for a duplex with separate driveways, entrances, back patios w/ storage, brand new roof, plumbing, newer HVAC, appliances, flooring, etc.

Adding rooms does create the potential for more conflict but carefully thought-out floorplans, designate wet and dry storage spaces, and provide supplies.

I didn't like the exchanges being hacked, didn't like the concept of cold and hot storage, 6 word passkeys layers on additional passwords, and those cold storage devices.I actually like my money as digits on a screen, partnerships, and physical real estate.

A storage unit is very different to manage than low income housing or a single family in the suburbs.

It's feasible for you to use an existing platform, most likely ethereum, and build your own variant of coin with specific conditions for smart contracts.
