The tank is not a storage device, though. 

The property is 1.5 acres with the 5 unit apartment and a 4,400 sq ft building that could be storage facility. 

As I was running electrical for the new storage units I was building down there I found 2 "Cherry" magazines circa 1982.

Home is a restored craftsman bungalow with hardwood floors, basement for laundry and storage, detached garage and yard. 

I would not screen them figuring it is more like a storage unit agreement.

Were you ever in my shoes?  

From the info you gave I am not sure how the storage situation is but I might consider doing minimum work and turn it into a storage area, maybe they can put their motorcycle, bicycles,  fake christmas trees etc.  

., with the remainder going to storage and shared laundry space.

Many landlords with ample storage space use this time to stock up on appliances for their next acquisition, or for things that break down with some regularity.Example: I think Lowe's has some good deals on low end washer/dryer sets that would make a nice amenity to your next tenant, if you have the storage space to hang onto it until needed.

Jesse you'll be in my shoes soon enough, lol.
