Threatened with eviction for not having a cosigner

[Garrett St Amand]

I hope I'm not abusing this website by asking from my (tenant's) point of view. I did sign up to eventually get my own real estate and am still working towards it. 

I woke up to this email

"I just saw that NONE of you have returned your cosigner agreements. I am attaching the lease and cosigner agreements on this email. If I do not have all 3 fully notarized and completed cosigner agreements in our office by this Friday, February 10, 2017, we will start the eviction process as your lease is invalid."

I didn't read the lease carefully when I signed, obviously. My credit is excellent and I have been living here with my roommates for 6 months now, but here is the clause in the lease that demands a cosigner:

24.Attachments: Guaranty Agreements (due on or before August 1, 2016), Lead Based Pain Disclosure

I'm not sure if I can get a cosigner by Friday, but more importantly this doesn't seem legal. I'm no lawyer, it just feels like a landlord could purposefully abuse this by "forgetting" about the documents, and then forcing an eviction by giving an unreasonable compliance time. 

Thanks a bunch
