As in 20 Mule Team in the laundry section of most grocery stores.

You have a lot to learn about the industry before you can even intelligently evaluate items (a) and (b) in your post.

One of the notes was on a building housing a restaurant in southern Colorado and another was a retail store in the mountains of Colorado.  

I will start doing those actionable items you listed.

I am a college student and I work at a hardware store where a large amount of our customers are contractors and landlords.

For example, your new tenant moves out on May 5th, you clean the place up and list it for rent on May 10th, you select a new tenant on May 15th but they can't move in and start paying rent until June 1st, then your previous tenant owes you rent thru May 31st (which can be deducted from their security deposit).Lastly, don't forget to send an itemized statement of any security deposit deductions within 21 days (in California), otherwise you lose the ability to make any deductions.

In my area it is $6 sf to replace. 2000 sf *$6 sf= $12000/ 10 year life span/12 months in a year= $100 per month for 1 item.
