Ok, so I have an update for anyone who is interested. I called references today, and boy am I glad I did (I know people are lazy and don't always). She gets glowing reviews, but the property management company mentioned they have violated parking rules and had an unregistered abandoned car parked on the lot, and apparently he got aggressive with the current landlord over some repair issue. I was shocked the current landlord would tell me this, as I could be his ticket to getting rid of them, but he seems like a slum lord and was slightly upset they might be moving. The death knell was the guy's credit score which came back and is below 600 with three late payments. Even though she would qualify if it was just her, I am going to go with the other better qualified applicant.
So definitely CHECK your references. You would be surprised by what even the current landlords will tell you.
