I started to airbnb my home in 2014 and was super successful with it, pulling in 11k a month and even had a couple commercials filmed there.

Medical marijuana, recreational marijuana and street marijuana all leave behind a nasty odor when burned that gets into carpets and drapes and smoking can leave a film behind on walls and other hard surfaces.it doesn't matter what the source is.  

The house has a lot of character and I even leased it to a movie company for 2 months for them to film in!

You can get a film for the window that would reduce the noise a bit.  

Have any of you come across a black film accumulating inside an apartment home?

And you’ll never get anything back for something that can’t be captured on film like a horrible smell.So add those replacement fees onto the maintenance fees that you’ll incur.

I plan on bringing a go-pro and filming it all as I change the locks front and back and make sure nothing is awry.

You can also use this process on end panels that aren’t wood but the film of a finish panel.

If it's just a laminate film applied to your existing windows, it will degrade in sunlight over time.
