Summarize this article:

After completing your termination notice letter, you will want to consider when to give it to your landlord. Remember, the notice period will not start until your notice is delivered to your landlord.  If you are in a month-to-month tenancy, you should deliver your notice letter along with your last month's rent. This will ensure that you provide the required 30 days notice and that you will have paid the last month's rent. If you have a fixed term tenancy, you should deliver the notice 30 days (or however long your state's notice requirement is) before the term is up. For example, if you signed a lease that ends on August 31, 2013, you should deliver your notice August 1, 2013. While you can give the landlord notice at any time during the rental period, if you give notice in the middle of the month you will be required to cover part of the next month's rent. For example, assume you have a month-to-month tenancy and you pay rent on the first of the month. You could give your notice on the tenth of the month but you would be required to pay rent through the tenth of the following month. After deciding when you want to deliver your notice, remember to look at your lease agreement or your state's laws and understand how you will have to deliver your notice. Make sure you follow the correct procedures to ensure your notice is valid. Once you have delivered your notice, be sure you vacate the property on or before the date you specified in your notice letter.

Summary:
Choose when you want to deliver your notice letter to your landlord. Deliver the notice letter to your landlord properly. Move out by the required date.
