I do most of my property management but I can't find any companies local...Does anyone know of a helpdesk type property management service for issues like no heat to troubleshoot things over the phone at 2 am?

I now have labels on the end of very safelight/TV/DVD cable to show where it should be plugged in to make troubleshooting easier and prevent me from getting a call.

Do you attempt to troubleshoot through call or message first?

As a PM, you can troubleshoot and resolve quickly, or... in some instances.. call BS on a guest, because you know the place better than anyone else. 

Questions/concerns that have come up include: setting up the devices on WiFi (whose paying for internet), teaching the tenants how to set these up, troubleshooting, and control/privacy (from the tenant's POV).I believe I will need Admin access to set up, change, delete codes for the lock which would require me to provide internet access (passing along the password/cost to the tenant).

Just trying to trouble shoot.

Hope this helps with your troubleshooting. 

Little did I know that would pretty much ruin my career since all I did was trouble-shoot things. 

Check if they are highly rated by the BBB.You can't trouble shoot everything, but hopefully this will give you some help getting started and setting up your mindset for renovations success.

The profit and salary an experienced contractor makes, evolves from an amalgam of foresight, efficiency, purchasing leverage, sub team trust, scope of work detailing, minimizing black outs, trouble shooting everything for every trade, phase, weather, material delays, cash flow.
