## Missing a notice deadline is one of the most expensive CRE mistakes

Lease dates aren't just administrative details. They carry real financial consequences. A single missed deadline can cost tens of thousands of dollars or more.

1.  ### Missed deadlines cost millions
    
    Missing a renewal option exercise date can lock a tenant into above-market rent, or force a landlord into an unwanted vacancy.
    
2.  ### Spreadsheets can't keep up
    
    Asset managers track critical dates in spreadsheets that grow stale. One missed update can mean a missed deadline.
    
3.  ### Complex interdependencies
    
    Lease dates depend on each other. A commencement date shift cascades through every subsequent deadline.
    

## What you can calculate

1.  ### Expiration dates
    
    Precise lease expiration from commencement date and term length, accounting for partial months.
    
2.  ### Renewal option deadlines
    
    Exercise dates for renewal options, typically 6–12 months before expiration with configurable notice periods.
    
3.  ### Notice periods
    
    Required notice dates for termination, renewal, expansion, and other lease provisions.
    
4.  ### Escalation dates
    
    When rent increases take effect, including anniversary dates and mid-term adjustments.
    
5.  ### Early termination dates
    
    Model early termination rights with configurable exercise dates and required notice periods.
    
6.  ### Custom date tracking
    
    Add any milestone with flexible offsets from commencement or before expiration. TI deadlines, delivery dates, more.
