All of the equipment and signage is gone, and I posted a lock out notice.

They sell their used equipment, including golf carts and UTV's. 

At first glance, there seems to a decent amount of value in several of the items... everything from 3 old Cadillacs that are in bad shape to old computer hardware, music equipment, power tools, hand tools, likely some antiques, etc. 

The Collateral paragraph says: All tangible and intangible personal property, including, but not limited to: (a) inventory, (b) equipment, (c) instruments, including promissory notes (d) chattel paper, including tangible chattel paper and electronic chattel paper, (e) documents, (f) letter of credit rights, (g) accounts, including health-care insurance receivables and credit card receivables, (h) deposit accounts, (i) commercial tort claims, (j) general intangibles, including payment intangibles and software and (k) as-extracted collateral as such terms may from time to time be defined in the Uniform Commercial Code.

I was reading my Bylaws and CC&Rs and I'm confused by some of the verbiage, it states, "...and shall also be responsible for the maintenance and repair of the plumbing, electrical and heating systems servicing his Living Unit and located within the outside perimeter of the exterior bearing wall thereof, including television cable equipment and connections, and all appliances and equipment located in said Living Unit."

You also have to look at things like CAPEX (does it need a $50k roof, or $80k worth of new HVAC equipment?)

You are training a gold fish to climb a tree and when you see it is hard to do, you will equip it with gadgets to try to make it work.Instead go invest in a monkey!

Or maybe the previous owner was worried about oil or grease stains.When we had our driveway redone, we asked for extra gravel and went with 6" of asphalt instead of 4" so that we wouldn't have to be worried about heavy equipment damaging it, but this is at our own home where we used to routinely drive heavy loads into our yard to get to the barn. 

For buying equipment?

Assuming you own your equipment and can take time out of your schedule to run over and do their home, it shouldn't cost much at all.
