We just closed escrow on a single tenant office building. The tenant has a month to month lease with the prior owner. We presented him with a new three years lease the day after closing and gave him a week to review the lease and get back to us. He verbally told us that he is not interested in a long term lease, but would be in contact prior to the deadline. He paid his lease in advance and thus a pro-rated portion of his lease was credited to our final closing statement. Basically, he is covered until the end of this month. However, he has not gotten back to us regarding our new lease as he had suggested. We intend to send him a Three Day Notice to Vacate or Quit. How soon upon sending him this notice can we evict him?

Does the written lease specifically allow a 3 day notice to vacate? If so then you can file a lawsuit for eviction if the tenant is still there after the 3 days has passed.

If the written lease does not specifically allow for a 3 day notice (or any other notice period) then you will have to give the tenant at least 30 days notice before you can file for eviction.
