Do my guests really need a (insert item for the home here)?

Reassess whether you need the home warranty, flood insurance, or other items.

But, there are certainly several items that would give me pause.  

There’s normally action items that can be implemented into your management process that are more effective. 

That could be achieved without spending an inordinate additional amount in cap ex; In fact all I have seen had these items in common1.

If this is a big-ticket item, you might consider legal action against Airbnb.  

Review what happened and determine why each item was above or below your expectations so that you can properly plan for next year.Review your prior year goals.Did you buy all of the properties you set out to purchase?

Compliance items such as adding smoke detectors, hand rails, fire resistant garage entry-door and new stairs outside.

Also, what others have said, the personal touches on what is in your place (e.g. providing all the essentials instead of having people buy TP, coffee, shampoo, etc.) and the quality of those items (no tattered towels, stained sheets, etc.).  

You make the payments to the lender.Oh, and just in case, there are more items to know about when considering a "sub to" transaction but this is just a comment on the payment aspect.
