Hey Dean - Any of those 3 products you mentioned could be potential options, and I'll add a 4th as well in case it's handy for any future properties (wouldn't apply here since this property is free and clear). 1.)

I would reach out to regional pre-fab operators and see if you can locate some of their product.

But, it’s good to know there’s a product that will help get rid of the smell when the lease is up.

THE MOST IMPORTANT THING I LEARNED ABOUT SALES IN 45 YEARS IN REAL ESTATEI, like most people, thought exceptional success in a sales field was due to a unique ability of an individual to somehow “connect”, “convince”, or “persuade” people to purchase the product or service the salesperson was selling.

Too bad, it's the most productive, honest work you ever did.

I couldn't find any information on the scam pages and this product does not come with a money back guarantee.

National Real Estate Insurance Group also has a lot of different products for real estate investors. 

I've never tried to look at if it can do texts, but it seems like something that a product like that could do... but the idea of a shared google calendar and calendar notifications might be good... 

This is the one I use:https://www.amazon.com/gp/product/B07J4VQCMF/ref=ppx_yo_dt_b...2.

If you are like me trying to remember a product or service that you heard about while on the go listening to a podcast is tough.
