You don't have to commit to a long-term lease, so it leaves you some flexibility if you need to relocate or upgrade your office space.

Space available for sublease is often offered at below market rates, and is therefore cheaper than a direct lease.

You will not have to pay a broker fee or commission.

In some sublet and/or shared office situations, the office space comes fully equipped with supplies and furniture. You might even have access to shared facilities such as reception areas and conference rooms!
