I answered this the same on your previous post. If I am understanding you correctly, you are saying that, while renting a property which the landlord listed for sale and is now in escrow (if it is in escrow, only a 30 day noice is required, not 60 days) the landlord gave you a 30-day notice. It sounds like you are further stating that part of your 30 days will be completed under the new owner. If that is what you are stating then, according to CA Tenant/Landlord laws (http://www.dca.ca.gov/publications/landlordbook/catenant.pdf
), you are required to vacate at the end of the 30 days.
I am not an attorney and am not giving you legal advice, I recommend you read the Terminations and Evictions Chapter starting at page 67 in the link above for furthr clarificaiton.
Regarding the new owner providing you notice, the new owner can enter into a new rental agreement with you at their discretion but I don't believe they would need to provide another notice to vacate while one has already been issued.
Hope that helps.
