Invest in mining.. precious stones and natural resources for EV Batteries 

The biggest issues with Vivint is the maintenance of the batteries.

The lock itself will still work via batteries if there is a power outage or the wifi disconnects, you just wont have app features until power or wifi has been reconnected. 

It depends on the language in the policy, but I wouldn't be surprised if the policy excludes coverage for criminal acts - like assault and battery, which this appears to be.

Keep a stock of double A batteries so guests or housekeepers can replace them as keypad locks seem to use a lot of power.  

I like to use the manual deadbolt option (meaning guests enter the code and have to turn deadbolt) as the battery last much longer with that setup. 

Schedule a time to change the smoke detector batteries/ HVAC filter and walk through the property to see if someone else has moved in.

Smoke detectors must have a nonremovable battery that can last 10 years.I have not seen a 9v battery that has an expiration date as far as 2023.This also requires that the 9v battery be soldered in.

Things I have come across that can lead to saving money, time, and headaches:-Smoke detectors with long-lasting battery-Low-pile and stain resistant carpet-Heavy-duty tile w/ lifetime guarantee -Long-lasting light fixtures and bulbs-High-gloss paint (easier to remove stains)I am curious to hear others weigh in on these practices and provide others.

There are extra battery backup packs and use motion sensors so they don't run 24/7, the power will last for more than a year.
