Do you have tips for structuring short-term leases that protect me as a landlord while accommodating their needs?

You need to log everything to protect yourself from any liability.Going back to your initial question--price is subjective.

A well written management contract should clearly spell out what is expected of both the PMC and the owner, to PROTECT both and avoid misunderstandings.

The later is critical to protect your investment.

We go above and beyond when it comes to protection.. starting with insurance coverage, sings in the listing and in the property that there is no guard on duty (as silly as that sounds), putting extra locking device high enough so youngsters can't reach, an alarm/beep system to alert them that door opens for those with small children (or elderly) so they cannot wander out in the backyard with no one noticing and risk drowning.

And, the longer you wait to act, the longer the squatter stays - and even gains some legal protections to stay while your waiting on a slow court system to act on an eviction. 

Quote from @Kyle Carter: What role does insurance play in protecting your investments.

The landlord should be named on the tenant's insurance policy for additional protection and to assist with tracking compliance.

The big thing is always focus on protecting the public, disclose, and take care of people.

Also, take as many pictures as possible before the tenant moves in, again this protects you in case of damage caused by tenant.
