14 Day Requirement to Return Security Deposit is Unrealistic!

[William Coet]

What to do:  The 14 day time frame is unrealistic to a situation and I'm seeking input on what to do:

Tenant left cat urine soaked wood flooring.  It will take us longer than 14 days to resolve and know the final cost.  Tenant is referencing the 14 day requirement and requesting a list of cost.

It will take us longer than 14 days to have a contractor complete the work and provide a bill.

Can we provide an estimate and deduct from the deposit based on that? 

Thank you.
