Expenses haven't been a major concern with this one, but I finally had to tell her Merry Christmas, last October. 

Christmas is scary.

You also will not have any way to know if this person just takes their Christmas bonus, sets it aside, and pays taxes with it.Basically, looking at net and worrying about CPA stuff is waaaaaaaay too in the weeds and micro-managerial of their lives. 

This past winter I signed leases on Thanksgiving weekend, Christmas Eve, and the first week in January.

Windows units are about as efficient as any other air conditioner as long as they are sized correctly.Personally, I'd buy a few window units and say "Merry Christmas".

My bank account during the Christmas holidays was breached because my Facebook was hacked on a couple occasions.

I once had a previous landlord served on Christmas Eve via Federal Express. 

It was close to Christmas when my property manager called me and gave me the bad news: one of the tenants was celebrating his son's birthday and invited the boy's uncle to the party.

The neighbors watch my more remote property, (a $50 gift card at Christmas encourages this) and the PM drives by my city properties weekly. 

Let's face it, how many people want to move around Christmas?
