How to avoid in the future: put in contract they are responsible for any drain clogs, noise problems with HOA, they need to abide by days HOA allows work, not have polka music or a router grinding all night long, not use HOA trash bins, block garages with trucks... all things that make the neighbors call the HOA Management CO.

But, she is just a really good agent, at least for me (although her awards and accolades does speak to her overal performance).Talk to a bunch and find one that you are, or at least feel, comfortable with. 

Play more music, one gig per month starting this spring. 8.

Recently a neighbor recorded a video of our roof shingles of our rental property blowing up and cleverly put it to music during a wind storm.  

I would try to lay out the situation as best as possible to a lawyer that specializes in commercial leases in your area that can help you build out a template that you can tweak for the different type of tenant (retail, maker, storage).Things to keep in mind are hours they are allowed in or must be open, noise/music, exact responsibilities for anything that could be considered a liability (snow removal near their entrance, tripping hazards just outside their exact space, etc), specify their insurance requirements, etc.

So far, they have paid rent each month within Chicago's allowed 5 day grace period of rent due date, and have not given me any trouble other than some loud music from time to time.

Works as a BT speaker but then can play any kind of music once you setup a special Amazon account for it.

I do get a little nervous seeing someone like Barry Wolfe say that he is imparting a sense of urgency on anyone who has been thinking of selling to sell now before the music stops, so to speak. 

Don't listen to music when driving, listen to podcasts (BP rookie and real estate are a good place to start)2.
