Hey all, so here's an update (if you're interested):
At the end of the notice to quit period, I swung by the house on my way to the Philly landlord court to file eviction -- there was a note on the door asking me to write my phone number because they didn't have it, and have no internet connection/e-mail capability (LOL...in 2017...the things people come up with as excuses). You've been a tenant for 2 years, I e-mail you a few times a month, you have my number and my e-mail.
Anyway, I wrote my number down and went to court to file. We have a court date on September 11th. Of course, e-mails started flying in -- I thought my roommate paid, I'm so sorry, we should have the money in a few days, etc.
I stopped by thereafter and gave them a copy of the court page (they'll receive an official notification anyway, but I wanted to hammer home the point), and I told them this could have been avoided, but when you radio silence for 3 weeks its hard for me to not follow my pre-defined procedures. They appeared real sad, but I think I know this game. They said they would have their money as soon as possible (still no money as of today) and they're back to not answering my e-mails.
Their lease is up at the end of the month and I told them I would not renew based on what I am seeing. They said they would be out by the 31st and pay the rent; both of which I think is unlikely. We'll head to court on the 11th I'm sure.
Any advice/recommendations at this point? I am going to let court handle this, but this is really killing my overall plan. I was trying to get the house on the market by the end of the month...
