If you've already started, the most invasive thing you can do is to install a WiFi camera/security so you can watch the rehab and make sure they are doing what they say.

Bring with you a notepad & pen, camera, 12 inch ruler, and flashlight.

@Molly MorlinoA couple suggestions:Install exterior smoke detectors that are Bluetooth connected to video cameras that will send you an alert on your smartphone when someone is smoking outside. 

.- Ring: All my cameras, and my Z-wave smart door locks for visibility- AirDnA: market research- Instacart: for emergency delivery of a blender when a previous guest steals one.- pricelabs: dynamic pricingRejected software: (If you work for these companies, or are associated with them don't be offended...they just did not work for me personally)- Rankbreeze: I was able to construct most of the SEO related experiments myself with a google incognito window.- tidy.com: I found it a bit cumbersome to navigate and use.Hope this helps!

Any advice on sharing the sifely door lock account and Blink security cameras?

I have a camera crew that will be using state of the art technology to complete the project in Hi Def.

Mine can set door codes, message (or call) guests, schedule cleaners, adjust the thermostat, monitor my cameras, & call a plumber just as easily as a local PM can, for 1% of the costHire good cleaners, a solid handyman & befriend some helpful neighbors.

Unfortunately, every minute that he dedicates to being "in front of the camera" (on the forums, etc), detracts from the time he can spend on the back-end, adding features, improving the design and making it more valuable for the users.In addition, Jon Holdman has dedicated a large part of his life to this site over that time period as well (unpaid), and between the two of them, they put in major hours making sure the forums are free of spam, staying on topic, ensuring posts don't go unanswered, providing links to old threads related to new threads, etc.By bringing on more moderators, they can spread the workload around.

Once the legal notice period has passed, enter, preferably with a witness, and either way with a camera, and fully document with photos the conditions found.

I would get a few security cameras installed.
