When is the effective date of the termination of an apt.

When is the effective date of the termination of an apt. lease?
I signed a 6 month lease with a June 30th termination date. At my choosing, I could continue the lease on a month to month basis. Early in the month of June I advised them that I did not need to hold over. I was told that I had to give 30 days notice of my desire to terminate and that my lease now extended until July 31st. There was a totally ambiguous statement about notification in the lease, but it was never pointed out to me or required that I initial to acknowledge the consequences. When I said that this was material to the contract and should have been pointed out, they said that it was too bad and that they were within their rights to charge the money. It seems to me that this is totally to the benefit of the landlord. The lease had a clear termination date, why was it not honored? What’s the point of having it if it isn’t honored? It should be that it terminates unless I advise otherwise. This is that it continues unless notified. The landlord is trying to catch people. I vacated at the end of June and they had all of July to refurbish and get it ready for rental. I received a bill for the month. What is the law on the subject? Thank you.

Roommate 30 day notice?

Roommate 30 day notice?
I am on a month to month lease and
my roommate and I are having
problems. My landlord said I have to
give a 30 day notice to her but not
to my roommate.

Is this true? Could I give a 30 day
notice to my landlord but give a
week notice to my roommate? Or
could she sue me? we did not make
or sign any agreement between the
2 of us regarding moving out.

I’ll have to check the lease
agreement for the ”jointly and
severally” thing…although I’m not
sure what that means as far as Im
concerned.

thanks

Want Deposit Back I rented an apartment (800/mo.

Want Deposit Back
I rented an apartment (800/mo.) and paid a $400 sec. deposit.
The apartment was on a month to month lease. The day I was to move in, I told the landlord I needed to back out of the lease and get my deposit back. This is due to last minute job relocation. The landlord refused to refund my deposit because she had to hold the apartment for me. I told her I was willing to give her half of the deposit for the trouble. She still refused to return my deposit. Do I have a case?
Thank you.
