My lease says the house does not permit smoking in the house. 

Vacancy - Rent rate and occupancy rate go hand-in-hand - monitor REVPAR per weekday/weekend/month to really know how you're doingutilities including wifi and surveillance - ideally with remote monitoring and locked in at reasonable temps, smoking/noise/party detectors perishable supplies (paper, coffee, soaps, etc.), linens (towels, sheets, comforters - they need to be thrown out every 3-12 months), Lawn care - not just mow and blow, but garden beds tooPest control - 80/qtr furniture - it doesn't last forever.Maintenance - normal + changing light bulbs, fixing furniture, loose doorknobs, etc.Administrative software - dynamic pricing engine, guest communication system Hosting fees - this is not a passive model.

Also, any electrical device that was touched by water or smoke had to be replaced. 

I have to do the smoke inspection to get the smoke certificate and have the Nest 2nd Generator smoke and carbon monoxide (https://www.amazon.com/gp/product/B00XV1RCRY/ref=p...) 

It seems to be following the same trajectory as smoking where there was a complete coverup with blanket denials and government bribes.

Also, google some sort of a fire and safety contract, so you can walk through and show them smoke alarms, fire extinguishers etc and have them sign it.

And in any rooms that have wall stains and odor from kitchen grease or cigarette smoke, do you like to also specify in writing any extra steps you expect them to take BEFORE painting those areas?

And this is a smoking hot market.

We are renovating 3 of the units currently and now making it a non smoking building.

The house smells like smoke and the vents in the ceiling are are black.
