No...NYS is very strict on how a tenant can be removed if they fail to leave on the date given. You would not be able to legally do any of the things you state. You would need to follow a lenthly eviction process...costing you plenty...to have them forceably removed. Evictions in NYS can last for anywhere from a few weeks to a few months, depending on the court and how many motions are filed by the tenants. It's can cost in the range of 2000 - 5000...again depending on how determined the tenants are to stay.
