I have used closed cell foam on one of them, back when I started. 

I know I'm further north (Sedona area) and a bit of extra driving, but if you are looking for hot ROI and appreciation for Single family STR's, or even just some no-strings guidance to help you get started in AZ, I'm happy to help.

Its more just, can we squeeze out an extra 10% of revenue by having access to a greater pool of people.

I am hesitant because if we use our credit card we don't want to be responsible for any damage to the room or paying for extra mini bar.     

I just like having extra cash just incase, so if I had the ability to just use money from my homes equity and was able to BRRRR and recoup that I could essentially continue to use that equity money over and over... atleast that is what my brain tells me.

If all you are worried about is payment not all the extras Cozy helps with Cash App is easy and you are instantly paid no waiting or processing payments right when they send then it is available to you.

You must be extra brave.
