I plan to use it for rent payments as well.Cozy has also introduced "express payouts" which, for a fee of $2.99, speeds up ACH payment processing time.

Aside for management nightmares, never-ending CapEx (as @Chris Clothier mentioned), and constant head-aches all the way around, one of the main reasons I stay away from pigs is precisely for that reason - I can't attract money to pigs...they are pigs for a reason! 

Their muscles ached for weeks as they gained the strength needed to throw so many pots.At the end of class, both halves were invited to enter their most perfect pot into the competition.

People from all over the world come here to practice medicine.  

What about putting in a medicine cabinet?

Until having children, veterinary medicine really maximized my time.

My upstairs neighbor was filling her bathroom sink up to wash a sweater one night (fancy sweater, I guess) - she turned on the faucet, sat down in front of the TV to wait until the water filled up, forgot about it and guess who found water streaming out of the medicine cabinet?

I work full time(medicine) and real estate investing only gets a small part of my time/money, mostly due to analysis paralysis :(.

What other criteria should I be looking for that may be an indicator of a head ache property in another investors portfolio?

So a spoonful of sugar (may) make the medicine go down smoother.Tip: use an attorney experienced in real estate (JV)'s to draw up your JV agreement (some take credit cards).Good Luck!
