Will work on some of these actionable items

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

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?

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

I will always look at the air handler and make sure tenants are installing fresh filters (most neglect this item).  

But enough to make to do all the cosmetics along with a few major items like HVAC, appliances, etc.

An example of a mistake was a line item for alimony that I found on my taxes (I am single and have never been married).

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

Given the scope of your work, a simple plumbing leak would not concern me, it's a $200 issue at the most and ideally, it's just another line item when you do rough in plumbing for the kitchen.Being in a Milwaukee suburb, I am guessing it's a 1960s ranch, probably with galvanized plumbing.

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.
