But,they smoke inside (against the lease) and therefore I have said I wouldn't replace doors and windows with them doing that because of additional damage it causes.Other than that, when they didn't pay that would've broken our lease I would've thought.

Things that we see as recommendations to fix after include:- cut back overhanging branches- add railings on stairs- fix cracked/broken driveways or walk ways- repair roof issues - clear debris from outside or inside- upgrade fuses to circuit breakers- repair broken alarm/smoke detectorsYou should discuss the inspection with your agent. 

I hadn't really thought about enforcing this policy until very recently, when it was determined during an inspection that the tenant had been smoking both cigarettes and marijuana indoors.

The house does not have any soot deposit nor does it smell smoke inside/outside.

Here’s a list of some of mine. 600+ credit score No smoking.

@Jimmy Chung You aren't going to find a smoking hot deal on the MLS these days.

Know 2 key risk factors before they even get the property address.How much did they smoke? 

Other simple things include grounding/reversed polarity of outlets (you can buy an outlet tester at Home Depot for $5), using foil-faced tape at furnace & water heater flue pipe connections, operable smoke/CO detectors, cracked/chipping/peeling paint if your applicant has children under the age of 6 (I think?)

One exception to your thought process many times in those areas that decay like that Commercial LEAVES and the nice NEW shopping gets built where there are nice new homes and incomes that can afford to shop.. what a lot of these areas is left with is the corner liquor store .. you know the ones that have Bullitt proof windows and sell cigarettes' one at a time..
