I could go totally nuts and do that thing where I buy Class B RV and try to live in it on $400 a month because I spent all my money on something silly like the whole disney library of digital movies... all 643 of them.

I don't think you'll have to pay double-digit interest rates for something like this, especially if you keep the LTV low. 

I might also do a single-digit rent increase if I wanted to keep her.

It is better to focus on Digital payments since they are not going away anytime soon. 

Do you already have a front door camera?

The company quoted me $1200 which included a camera inspection afterwards. 

You could take that and put it on a tablet and have them digitally sign each page on arrival.

I think it's speculation in what appears to be a peak market with very little room to go up and a lot of room to go down.I absolutely agree with this, seems the future is less likely to continue the trend of double digits appreciation and more likely to dive into negative territory 

But then I had nightmare's of Holmes on Homes showing up at MY house with TV cameras and chose to go with 2 systems!

It required a hefty $15k camera inspection both before and after the cabling, just to ensure we weren't inadvertently wrecking any existing pipes or sewers.
