They were also urinating on the carpets in 4 stair wells and the urine odor was horrible.I knew I could not stop these ghetto people from drinking and urinating on the stairwell  carpets, so the day the property closed escrow I terminated the tenancy for all 14 tenants because I knew some would move in 30 days, some in 60 days and it would take an attorney and 3 to 5 months to get some tenants out.When I started remodeling the property there was so much cockroach crap under kitchen cabinets we literally used a square shovel and a large trash can to remove the dropping (or whatever that crap is called), but the point to my story is; I am never afraid to make start a major storm when it comes to evicting tenants, remodeling and spending tons of cash because I know that when I stretch out the numbers over a 10, 20, and 30-years the profits become amazing.I am guessing that you have purchased a goldmine for $150,000 and you just don't know how to turn the property into what you need it to be.

Tell them (truthfully) that smoke odor lingers and professional cleaning will have to be done at their expense, ie the security deposit.The sale thing is a red herring.

I pay more attention to the pad (spend the $ to upgrade to an 8lb pad with some stain/odor fighting abilities).

If you want to continue trying to clean them, get a professional carpet cleaner and have them treat it with enzymes or something designed specifically for pet odors.

Cigarette burns are not "ordinary" and neither is the cigarette odor.

My house was just painted with ICI Lifemaster 2000 - The first solvent free, no VOC, low-odor interior latex paints.

Torn blinds, scratched doors, torn carpet, burned or dug-up lawn, odors, chewed trim, and more.

Also, ODOR is a huge issue.

I had a house where the shoe at the bathtub drain was leaking into the crawl and causing an odor.

Their kitchen is directly beneath mine and whenever they cook, their cooking odors travel up and become overwhelming in my unit.
