Legal Question in Real Estate Law in California

No

Absolutely not. A lease is, in many ways like a lien, only with an expiration date. If it attaches before a sale or another lien, it has priority over any later transfer or encumbrance. The only options are cancel the lease by agreement (apparently requiring payment), wait until he does something that warrants eviction, or let him stay for the term of his lease and then kick him out.

No. A change of ownership of a property does not affect the rights of tenants under their leases. That's how huge office buildings with dozens or hundreds of tenants get sold. In rare instances, a lease will contain a specific provision making it terminable upon a sale, but such clauses are the xception, not the rule.
