When you are in the position to walk away from a lease as an existing or potential tenant, you will always have the upper hand. Landlords will do quite a lot to avoid vacancies and starting early gives you enough time to negotiate with that specific leverage in your back pocket. During lease renewal negotiations many landlords will offer tenant improvement allowances, amongst other things, just to convince you to stay. We recommend starting looking for a new space at least a year prior to the expiration date of your current lease. This assures you have enough time to do your due diligence on everything from market analysis to your tenant-only representation.
