If you are leaving the water on in the property you can purchase freeze alarms that you can place in basements and crawl spaces that will alert you if the temperature drops below a pre determined temp, additionally many of these sensors can detect water so if placed near a hot water heater or water source they can alert you if there is a leak or backup.

What's the craziest thing a tenant has told you in relation to your property that absolutely set off your "BS alarm" but turned out to be true?

-install a gas leak detector or alarm in the rental unit-spell out in lease agreement that tenant is prohibited from removing the gas leak detector and that tenant must notify landlord immediately if at any point the detector stops working-do semi annual walk through inspection of the rental unit to make sure the gas leak alarm stays installed and is working properly and that the gas stove is working properly.Is there anything else we as landlords can do to minimize our exposure to being sued in the event of a gas explosion in the rental unit ?????

Also NH requires all units have hard wired smoke alarms and fire extinguishers.

You have a buyer/borrower with 0 of his own money in the deal; you have 100% leverage; you have a 1st position lien that’s not  “arms length”, increasing the likelihood of the seller and buyer getting together to do a “friendly” foreclosure and wiping out the 2nd lien holder; and you have all the alarms and triggers going off when a property buyer attempts to borrow of finance the down stroke.A more likely financing possible scenario would have the buyer giving up ownership equity to a money party.  

But I would also get an alarm system instead of going over to check if he is away for more than 7 days.

To piggyback off Jonathan's question - 132% is a big, massive uptick and it sounds alarming.

Updated fire alarms -What was the outcome?

The tenant in this story is most obviously a good-for-nothing, stick-at-nothing, self-justifying-everything thief.

Think about the things you need a place for next to the bed at night - an alarm clock, eyeglasses, phone, glass of water, book.
