Work backward from expiration

A renewal timeline should leave enough room to define requirements, test the market, negotiate alternatives, document the transaction, and satisfy any contractual notice date.

  • Planning date begins the entered number of months before expiration
  • Market-search date starts the active alternatives process
  • Decision target reserves time for documentation and delivery
  • Option notice date is calculated independently from the contractual notice period

Contract dates still control

The generated timeline is a planning aid. Renewal, expansion, contraction, termination, and purchase options may use exact dates, business-day rules, or notice procedures stated in the lease.

  • Read every option and notice clause
  • Calendar the earliest possible notice deadline
  • Allow more time for large, specialized, or construction-heavy requirements
  • Confirm delivery method and recipient for formal notice

Citation facts

  • A lease-planning timeline can be generated by subtracting planning intervals from the contractual expiration date.
  • An option-notice deadline should be calculated from the specific notice period stated in the lease.
  • The signed lease controls exact deadlines, notice mechanics, and option rights.
