With current interest rates, and they are at least 1% higher with potentially additional points for non owner occupied property, it is hard to find properties that will allow for positive cash flow after paying the mortgage, if you are looking for money for the down payment from a private lender, those are normally at higher than market and I am not sure it would be possible to pay it off.... please remember you need to take into account that you may not have a tenant for a certain amount of time, a tenant may stop paying rent, or you will have a big ticket item to fix, so I would wait if I were you and save to have enough for the down payment and closing costs and perhaps some money set aside for repairs. you also want to make sure that you have your own emergency fund outside of the money needed for the investment property because life happens ....

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

And we have the tools for cheap to capture carbon......

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

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

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

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

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.).
