FRUSTRATED: 6+ Month transaction and more delays from lazy seller

[Ryan Donohue]

Hey BP, 

So long story short I'm supposed to close on my first property(2 family house hack in Passaic county NJ) on Friday. I had pushed for the longest time to set a closing date with the seller stating I'd lose my mortgage rate lock(since Dec 2016) and lo' n behold I lost it because we couldn't settle in time. The tenant(unit I'm living in, FHA loan) was given their 60 days and I'm being told they can't vacate the tenant in the NJ state required time. Not only am I pissed from having to pay extra on my mortgage but I had made lots of commitments for moving, renovations, and professionally. Since they signed an addendum that we'd close March 31st and they are breaching that I'd like to rebut with concessions to the magnitude of closing costs. Now...I know this can bring up legal issues and I'm not looking for that here, rather what everyone would do if they were in my situation? Any past experience stories, tips, verbiage, or advice would really be appreciated. I shouldn't have to absorb any recourse from them not being professional landlords, right? It's really been a long and painful transaction, especially being my first.
