Also the plumbing inspector will prob require you camera the sewer line and get that inspected by the water Dept before final.  

I will add internet and cameras to the facility. 

Define a $5000 used cameras going to set you back you’re already writing a very thin line financially.

I suggest you install security camera aim at the front out and at cash register.

Our environment cannot always be controlled by a system of locks and security cameras and access cards.BTW - I took your advice and checked out a Sig P229 in .357sig.

I think I would also like to have cameras but that may be difficult to set up in a rehab, better for your home where you have internet access perhaps.

Plumber snaked camera into pipe from toilet and identified broken pip with water popped where it shouldn’t be.

In inspection see about getting a camera to check the main lens pipes in the place if you can after reading the whole lateral belly sewer belly thread it's with it to find out up front.

When I was first told "there'll always be another great deal", I didn't believe it ;) But, there really will always be another great deal.Take a flashlight, a camera, and something to take notes on.

You could put a home security internet surveillance sign in the yard so they think the house is under surveillance or something similar.
