I'm sure they will get smoked in the months ahead. 

Smoke free / Pet Free is a great advertising sign.Your "Pet Move in Fee" is a non refundable payment.

I also realize now I should have paid $500 for a smoke test when I was doing due diligence before buying.

For instance, if your unit is listed as 'smoke free' and the PM has been notified and is now aware that someone is smoking in the unit but does not take action to remedy it, the PM could potentially be held liable if they don't take action.

Be smart, yes but holy smokes have folks lost their marbles. 

I bought a flip property needing light cosmetic work (new flooring, cabinets, counters, appliances, minimal drywall and electric work, smoke smell removing and paint.

My tenants are having a long standing conflict, the people upstairs are smoking weed outside of their window, and the smoke is drifting into the windows of the people downstairs.

Up here, I am hearing from closing attorneys that no cities are performing water readings, smoke inspections, etc... and appraisers and home inspectors are not moving either...I can only imagine the Housing Authority...I would generally plan on at lease 1 months elapsed time with a Section 8 tenant under NORMAL conditions. 

Stopped smoking (I’m sure someone will rip into me for suggesting that one)?

One person has a dog (Spaniel) and I believe he smokes as well.
