This link has a sample of such  a letter.

I'd ask for a sample Scope of Work.

You only have a sample size of 1, but deconstruct your result abit, if possible, and see if there were any clues from the call you received. 

Every time I had a problem with a tenant I have found that there is one or more paragraphs in the lease that can be used to resolve the problem in my favor.They have samples for all kinds of many other documents on their site as well as weekly e-mails that expanded my landlord knowledge.

Also if you can exercise "house hacking" out here it would be great.

The IRS very seldom exercises their right of redemption.

I'll also add that under Colorado law you don't need to own the property to be held liable under premises liability law, but rather the definition of "landowner" under Colorado law is a broad one which includes not only the titled owner, but also anyone who exercises a sufficient degree of control over the circumstances existing or activities taking place on real property where the accident occurred. 

Here is the sample.

$x if exercised within 12 months, $x + 3% if 13-18 months, etc.
