Remote management of vacation rental - tips?

[Scott V.]

So my plan is to remotely manage a few vacation rentals I currently own. Trying to set them up to be as "hands off" as possible. I have local resources to help out if needed, but trying to minimize calling on them. I'll have a cleaner/turnover person and a handyman. Obviously, I would "dummy proof" the rentals as much as possible and have manuals/FAQ to minimize questions but wondered if I'm missing anything or if anyone had further advice?

I have the wifi router inaccessible to tenants (so they won't turn it off). It's shared between the two properties on the same lot FYI. I've thought of getting a wifi outlet to plug it into, so I could remotely "reset" the router by turning off the outlet, then back on. Any recommendations?

I have purchased an August lock with keypad and plan to use the keypad only for guests, issuing them a four digit code that is the last four of their phone number, good for only the time of their stay.

Cameras outside the properties so I can see what is going on, if a door is open, lawncare situation, etc.

Alarm system, I'm trying to figure out if this would be more trouble than it's worth (another thing to break, confuse guests). Or should I get one that is armed/disarmed by the August lock (it looks like the iSmart Alarm does this). I would like to have a flood sensor though, figure that's a good idea.

Any other suggestions for remote management? Thanks!
