Someone telling otherwise is blowing smoke you know where.

Trying not to give too many details here, but Synthetic marijuana is usually rolled like a cigarette, crack is typically used in conjunction with a very small glass pipe (meth too sometimes) and needles are used for numerous drugs.

I have a clear “no smoking”on the property in the lease.  

I know that banks will not lend if the property is not "habitable" (e.g. electrical, plumbing, etc.) but will they not lend if there are certain items on the CO report that have not been fixed during a refinance (e.g. window needs to be replaced, interconnected smoke detectors, fire code items, etc.)?

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.
