I FOUND SOMETHING IN MY LEASE! Check this out:
"In the event such written notice is not given or if the Tenant holds beyond the initial term, the tenancy shall automatically become a Month to Month tenancy upon the same terms and conditions contained herein and may thereafter be terminated by either Landlord or Tenant giving the other 30 days written notice prior to the last day of the then current period of the tenancy."
So does that mean what I think it means?
Yes and no. As mentioned earlier, the "attached to the door" statement is something that clearly tips the scales in the landlord's favor; assuming the landlord can produce a backdated document copy, he / she could stand up in court and say, "We went above and beyond -- we gave several months notice in advance." And, yes, many landlords will have no problem doing so.
Even so, you received notice today, technically. The end of the current period of the tenancy is July 31, and your landlord has informed you that you are to be off the premises by then, as the property has been newly leased for a term beginning August 1. That's clear-cut. You've been told in no uncertain terms that you are not welcome to enter a month-to-month arrangement, and you are not welcome on the property after 11:59 p.m. on July 31.
That said, since no one on this board is, to my knowledge, licensed to practice law in the State of North Carolina,
open up a goddamn phone book and call a lawyer. I cannot repeat this clearly enough, speaking as someone who's been embroiled in a landlord / tenant dispute that eventually went to court.
Here. Go nuts.
