Make sure you have smoke and CO detectors in appropriate places, GFCI outlets near water, functioning mechanicals, make sure everything is in good condition and you shouldn't have a problem.

In Orygun its dark and raining so we over size our windows I would say our homes let in 50% more light than a Lennar house and their windows that are done to minimum UBC code..

Police drive by occasionally and see 3-4 people standing outside smoking. 

No one is perfect though in RE if your doing volume your going to have a few that are bummers but at least in our program there is control.. not this feeling of helplessness when you hand your money over to a syndicate and they go dark your totally out of control of your funds..

My other issue I think of when it comes to that is I'm in the process of switching everyone over to non smoking. 

When the smoke clears after a sale, everything falls to the buyer's responsibility.  

I am wondering if anyone has experience with Wynd Smoke Detectors and if they’ve had success with them detecting marijuana smoke?

They do not just stop paying because there is a door knob loss, or a smoke detector missing a battery. 

Cameras do not catch her actually taking anything because it was dark.  

Mold needs warmth & humidity, and preferably darkness.
