Seller pushing back close date, what can I do about it?

[Brendan L.]

First househack duplex, our contract had close on June 16th. I took 2 weeks off work between then and July 1 to make my unit livable. Those dirty tenants can't move into their new place until July 1. My lease is up June 30th, so I'd need to relocate for at least 2 weeks. I'm also losing the time I would've had to make the place habitable, I'd have to scramble to work on it over the weekends while living in it, not ideal.

I don't have a ton of leverage- this guy just got rid of his ****** tenants thanks to me and he could just as easily walk away and rent for longer, but the place has been on the market off and on for years. 

What would you do? I can still do it, it just sucks to lose that time to work on it and have to move multiple times, but I feel like my hands are tied because I'm already $800 deep on the appraisal, etc.. I might try to see if he'll remove the ****** carpet thats in there, but I might have to swallow my pride, ugh.
