Lets see if I can spell this out a little more clearly.

You must give your landlord notice. That notice must be the same as the intervals in which you pay rent. If you pay rent monthly, you need to give 30 day notice. If you pay rent weekly you must give a 7 day notice.

Eugene you seem like a bright chap and I am sure you have as many tenants as Econprof. Most leases actually contain a hard to find area that specifies the periodic rent payment. This is defined as the time between rents. This is the same period as which you will need to give notice.

Tell you guys what, the OP can follow your advice or my advice and let’s see where he comes out.

Additionally the LR form you are referring to Rus also specifies a period of payment to it as well. I believe at the end of the lease where it talks about the inspection for moving out, it states that the tenant shall give the landlord a notice of termination of tenancy, form NTT.
