## Summary

Work backward from lease expiration to create a visible renewal or relocation planning timeline without hiding the assumptions.

## 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.
