Commercial leases in Houston, Texas frequently have language that changes the rental rate after the end of the term of the lease. Often the rental rate after the lease is over, is 125 to 150% of the regular rental rate. This rate is called the holdover rate. If your lease is about to expire, and you have not negotiated a renewal or made arrangements to move, you should check your lease to see if you have to pay a holdover rate. Ask a qualified lawyer in your jurisdiction for help in determining your rights.
