She we give her a 30 day notice?

I have a tenant that is tenant at will and according to my lease agreement I only need to give them a 30-day notice if I no longer want to continue their month to month lease.

Hi,I just purchased a SFH 2 months ago and received a notice from the mail from my lender that there are delinquent taxes over the past 3y from the previous owner.

You have to play by the rules or face some serious consequences down the road.The solution is to sell your property in California while markets are at a peak (that's today, if you haven't noticed) and invest your money in a different market that has reasonable laws and fair courts.

The answer is in your post....have the seller issue the 90 day notice to the tenant now. 

OP - you'll notice that the Realtors and Property Managers all say it's no big deal....... :-)I, for one, would never do it.

How long did it take from the time you got notice?

Also I've noticed a lot of CPAs post here on BP too.

I would also file a 30 day notice. 

TODAY -before the sun sets - send/post a Notice To CURE to the TENANT (not the son) for allowing non-lease disclosed persons to reside at the property; in your state, the cure period is 3 days ("1161(2)).
