I use the $75 kwikset 909 in all my AirBnbs and have never had a problem (as long as your property manager changes the batteries).https://www.amazon.com/dp/B00N...EDIT: I also swap the locking knobs from the front doors with the hall/closet knobs within the house that I want to turn into owner's closets.

In any case, I found the following after she moved out:- Smoke/animal smell throughout the unit (she was a smoker and smoking in the unit was strictly prohibited and dog was allowed per the lease)- Carpet with cigarette burns and soaking wet at the time of removal (no telling how long its been like this)- Rear window has a broken pane (still functional as it is a double pane, but needs to be replaced regardless)- Holes in drywall- Replaced bedroom doorknob with deadbolt (because her middle school son was stealing cigarettes lol)- Backyard full of metal/wood fragments and general rubbish including shoes, a knife, batteries, fishing reels etc.

I have found that the Dewalt batteries lasted me longer per charge than ryobi did and the ryobi only came with one battery.
