Tenant Witholding Rent and Payment of Utilities

[Mauricio A.]

So after sending a termination of the lease renewal, the tenant refuses to pay rent and has not paid the water bill for the last quarter (usage also increased significantly on the most recent month).  The lease is due to terminate in the beginning of March, however, what are my options now that they haven't paid the water bill for the last quarter and are running late on rent payment?  The lease dictates that they will be in default after 10 days of non-payment for rent, but I wonder if they're trying to draw out the process as evicting them would likely extend beyond the date of lease termination (and be more costly as well).  How many of you have been in this same position and what have you done or learned from it? 

Thanks!
