There are many reasons why a Landlord and Tenant may choose to include an “option” in a commercial lease. The most common type of option is one that gives the Tenant the right to extend the lease term, usually for additional — sometimes two or more — terms of equal length to the original term.
If the landlord sells, dies, or transfers the property, the new owner has to honor your lease and any other agreement you made with the original owner or management, unless the lease agreement specifically states that the lease will terminate in such case.
The short answer is yes: Renters usually have options for breaking their lease to buy a house. The long answer is that it depends on how you go about this, and how it works depends on your lease agreement and your landlord.
For example, a tenant and landlord may agree to a five-year lease with a five-year option to renew. At the end of the first five years, the tenant is given the chance to continue the lease for another five years. If you think you may renew, be sure to bring up extension provisions with your landlord.
There is no legal automatic you get to break your lease because you are buying a house law. You will need to discuss options for terminating your lease early with your landlord, but you are responsible for taking care of your lease, either paying it or meeting the terms for early termination.
Although some buyers do that (and apparently think it's permitted), the answer is no. Unless the lease specifically states that the lease may be terminated if the tenant purchases a home, the tenant is not allowed by the lease to terminate it.
