Hello: I checked the posts under this heading and I scanned the court cases as you suggested, but I didn't see anything, so here goes ...
My 6 month lease (from the previous owner) expired at the end of April. My new landlord accepted my rent check for the month of May, which makes me a month to month tenant.
On May 2nd, I was notified of a hefty rent increase. The increase takes effect on June 1st. On May 17th, an employee of the landlord came around with a new, 1 year lease. The start date is also June 1st.
I can't find any guidelines on these issues. Can you point me in the right direction? Location - Upstate NY.
