Firstly - consider it if you are unsure of anything, and want clarity. Before renewing a lease consider negotiating new terms or obtaining needed improvements. Even with an option to renew, the tenant is always able to renegotiate the terms. Often the marketplace has changed and the terms of your option-to-renew that looked good five years ago are now part of a more competitive market. A tenant representative can let you know where you can improve the terms of your lease, how they compare to the marketplace, and even negotiate with the landlord on your behalf.
