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.

@John Thedford  what Oregon did was to include  "equitable interest" in the definitions.IE the trading in equitable interest for expectation of profit is now considered selling real estate and a license is required.. there was a module on it in my CEAlso if you go to the state of CA BRE website BIG tab right up front

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.

We had our house burn  down   a total loss  due to a remote control  traxxas  battery charger within 30 minutes whole  house suffered  smoke and water damage happened  about  a year and a half  ago thank God no one was home and it happened in the day time.  

Simple question, who is responsible for the upkeep of the batteries of smoke alarms?
