Evicting vacation rental tenant for smoking in no smoking house

[Katherine Pinkerton]

I am brand new in the vacation rental market. I have a very nice property, furnished for short term monthly rentals.  The listing clearly states no smoking several times through out the description.  The tenants have been smoking cigarettes and weed in my nice house.  They have been asked to stop but have not.  My property manager has pictures.  They are slobs and completely disrespecting the property.  We are trying to get them to leave because of the smoking.  The owner of company these men work for is demanding remaining rent back plus security deposit.  I don't want to give security deposit back until I see how badly they treated my house.  I am sick over this.  They are my first renters in a pristine home.  They blatantly keep smoking. How do I get them out.  There are 3 more weeks on the ageement.
