That can be a normal expiration (as in a lease), a notice-and-out, a buyout clause, or something similar.

Here's one:"What do I do when tenants won't return the lease extension documents and the lease then expires?"

Chris,  Thank you for the tip, I'm keeping all the rents at the same rate as the previous owner until their leases expire in May.

I include the following in a Landlord Addendum to all my Leases: The provision generally summarizes provisions contained in the basic TAR Lease along with a few other stipulations:Early Termination of Lease: (Reference Paragraph 28 – Basic Lease) Tenants may terminate this lease at any time under the following conditions: (1) Tenants are responsible for the lease payments until the Contracted Lease Expiration Date (Paragraph 3 of Basic Lease), or New Tenant(s) ACCEPTABLE to Landlord Are Approved, and any Security Deposits and First Month’s Rent has been received. (2) Tenants will pay 100% of one month’s lease amount if the Termination Date is more than 60 Days prior to the Lease Expiration Date (Paragraph 3 of The Basic Lease), (3) Tenants will pay any and all expenses incurred (such as Utilities, Lawn Care, Re-Leasing Fees, etc.) while the property is Vacant.

If it's game over in 3 months, my guess is your budget expires before you make money - but that can all vary on your market, luck, negotiation skills.

If they are not moving out for some reason or breaking rules of the lease, or their lease is expired, they can't stay there anymore and they are trespassing, you can kick them out with 1 phone call to the police.

Hey guys, need help since it's the weekend and need to figure stuff out by opening tomorrow am...My lender (PNC) called to let me know I can streamline refi my existing mortgage based on, I believe, some kind of expiring HARP option.  

note, the three day pay or quit period have already expired.  

Tim, If your goal is to renovate the Property, with existing tenants, you may choose to delay the renovations until the Current Leases have expired.

Got a call on Friday from the owner and she stated that her current contract with the highest bidder was expiring that day and wanted to know if I was interested in seeing the property.
