I've heard mixed reviews that they units often die way before that and have a much higher rate of false alarms......

I would find a reliable contractor to take a look at the potential issues and let him tell you whether the inspector was right to have cause for alarm or not.

AND there is no contract like traditional alarm companies require. 

Does the security system alarm call your tenant's phone or yours?

But it’s not over.When AR went to survey and prepare the house for marketing, they discovered something alarming.

So theoretically that brand of deadbolt and something like an August Pro lock might be a bit more break in proof, but I think a really determined thief will get into most places, and I have other lines of defense, so I'm not too worried about drilling in this case, and I prefer having a touchscreen/keypad available and not be 100% dependent on phone or key to let me in, as is the case with August locks.

My property will include an alarm system and monitoring with the rent.  

I can tell you every story about what’s gone on in my block in the past 13 years from the time the neighbor’s roommate was selling drugs, to the time the thief was caught breaking into cars to steal GPS, to which old folks died and their homes were bought by investors and flipped (usually to young families).It doesn’t take a lot of crazy parties or bizarre events to really disturb the neighborhood psyche.

The part of the article that alarmed me the most was this: "the money he offered me wasn't even enough to buy a decent tombstone for my daughter." this was said by an 81-year-old woman named Mattie Qualie, whose daughter, Lorraine Woods, age 58, died in 1998 from an alleged long exposure to molds.

The key building systems are the plumbing system, electrical system, HVAC system, elevator system, escalator system, fire protection and alarm system, gas distribution system, and the security system.1) Expenditure to these systems is most likely to be an improvement because they are small UOP.
