In such a case, I would avoid a Boiler Plate Template that can be downloaded, from the Internet or purchased in an Office Supply Store.

Looking for the best website or mebership service where I can download the latest lease agreement templates if it can be specific to California even better.

OR download from https://www.biggerpockets.com/files/user/CosIorg/file/asspro-cya-diagram-v6a-solo-401k

Also, I have downloaded a general lease agreement from Brandon Turner and it looks really good.

Hey I know its not on topic but your spreadsheet looks awesome, very aesthetically pleasing and clear. is it downloadable somewhere?

Now that I'm a proud owner of my first single family home, I was thinking of paying them to download copies of their lease agreements for use on my own homes that I was planning on renting out.

They're invalid if you just try to download them and use them anyway.At one time BP had a forms inventory of leases for different states so you might want to check this website.Otherwise you can engage a realtor to help you get your property leased and they can use the TAR lease.Also probably common for PMs to use this or have their own lease forms written by their attorneys.   

Here is a free download for TCMA Standard Handbook on how to tile and what systems to use. http://www.tcnatile.com/products-and-services/publications/218-english-publications/188-handbook.html

You can download the app and have access to a great compilation of courses from around the world, including Cambridge, Oxford, Yale and Columbia, among others.

Downloading someone's spreadsheet application will do little for you if you have no understanding of the concepts and what they mean.
