Generally, I try and honor this sort of request, when it's reasonable....but, she is not being reasonable at all, and is requesting service that is not standard operating procedure for scheduling this sort of work.

Take those things and create habits around them so they become second nature if they aren't already.I can't speak to the outcome of any of the aforementioned programs.

My question is where do I go to get the information I need: Legality, zoning, procedure?

A war in China, a natural disaster, a crazy tweet from the White House could easily trigger a recession and make your knowledge irrelevant.

First a person must have a qualified DISABILITY, then comes the ACCOMMODATION.Establish a clear policy and procedure about making accommodations.

Anyways in 5 months we wiped out many years of profits thanks to rent control, lawyers and human nature.

—When the lease is silent on the procedure to be followed to effect repair or maintenance and the payment of rent relating thereto, yet affirmatively and expressly places the obligation for same upon the landlord, and the landlord has failed or refused to do so, rendering the leased premises wholly untenantable, the tenant may withhold rent after notice to the landlord.

It really varies by the state Naturally, the first thing to jump out is the term.but generally there are specialized amenities, increased entry maintenance, and possibly specialized rules.again, your state laws will guide a lot of this.more important than the lease, especially in strong tenant rights states, is discovering who you are leasing to! 

That obligation is the very nature of acting as an 'agent' on behalf of the seller.

Being first to the list agent is sometimes useful (more so a few years ago than today, but first never hurts) being first immediately after a price reduction or a change in list status from pending to active is yet another.For me, pursuing million dollar plus properties was two fold, one, it was a natural progression for me and the next step in the ladder for my business and two, I saw the market was starting to change in late 2011 in that properties we're becoming more difficult to find (good deals), competition was increasing as more all cash transactions were taking place, and I knew that my strategy of using my relationships with top REO brokers and asset managers who were giving me deals BEFORE they ever hitter MLS would not last much longer, thus, I had to play the numbers game on the MLS like everybody else (or direct market).
