The only drawback I see is that Google could change or discontinue the service at any time, as they've done occasionally with other services. 

Our "all-stars" receive special benefits such as having their unit upgraded first when we do upgrades, special requests are more often accommodated, and occasionally we give them a special thank you gift.

Most systems, however, require remote monitoring and occasional inspections.

I'm able to do most of my management duties during my lunch breaks and in the evenings, with the exception of occasional phone calls and emails throughout the day.My biggest challenge is meeting our handyman/contractors at the property for maintenance calls since the majority of them want do it during the 8-5 working day.  

Even in my Sec 8 properties I do ceiling, walls and trim in different colors/sheens (and occasionally an accent wall if I have some odd leftover paint).  

I occasionally stop by another forum like this, but for realtors where a lot of high volume realtors talk shop (I personally pretty much just handle my own projects, but these realtors work with LOTS of buyers/sellers) and there are enough stories on there of the various hassles and downright hell that yet another ridiculously inaccurate zestimate has caused yet another realtor.

Would this property appeal to roommates or a parent and adult child or a couple who wants a little room for occasional guests?  

they thank me for the reminder.I would occasionally be asked if they could sublet their place for the summer. 

We'd occasionally get roof rats and would have to bait for them. 

You'll also get the occasional group of drunk students walking by as they are going from bar to bar, and the ambulances also use this street, so if you need a quiet place, you might want to look somewhere else.
