I am interested in both, looking at a self storage facility this week and am looking at multiple commercial investments with clients 

Does anyone know of units that are easy to buy, install and don't have a monthly cloud storage fee?

If the market doesn't tank, you will lose the premium you paid like an insurance premium.  

For example, the biggest thing in the back of my head is that once mortgage forbearance as a result of COVID ends, there could be a wave of foreclosures that could tank property values, at least for a short while.

Adding storage in the back is usually a good idea but look at the ROI on it.  

Nice returns - all of my notes produce double digit returnsWhat do you mean by "storage space"?

I've even considered trying to buy a storage facility or a car wash.What kind of down payment % should I expect on a commercial loan?

Looking at dozens of deals, economy in the tank, having a lender. say "no",  getting beat out of a deal...the list goes on and on.  

REALTOR, my office manages 400 rentals and about 350 storage units.

You don't want to start a relationship to learn about storage units and then find out they only invest in single-family homes.3.
