Since you're the Landlord, it's just a money shuffle, but it helps you remember that the roof over your head has value, you can better track numbers on the property as a pure investment, it helps you stay disciplined about setting aside money for the next investment, etc.How to calculate cash flow: https://www.biggerpockets.com/...

Aloha,You can easily find a battery operated data logger for as little as $25 that will record and chart the temperature over a period of time.

I have painted all of my houses pure white (eggshell sheen) for years now. 

It keeps your numbers pure so you can show them to a lender or potential buyer later on, it keeps you disciplined, and it allows you to save up for the next rental easier.

Also, recently Forsee power a French EV battery company announced it will be setting up U.S. headquarters in Columbus OH which is exciting.

The problem is that the stock market chart is even better in a pure appreciation context.

Original cash flow was at $198/mo but with less in the deal, cheaper insurance, and depending on rent rate, my pure cash flow could be up to $400/mo.

But just like any lock, installing it correctly and ensuring you replace the batteries when they get low is something that you will need to do.

From a purely investment perspective I agree with @Andrew Garcia !

Suppose it is a risk benefit analysis since my crystal ball seems to have run of batteries 😁
