I know the larger/commercial property managers play this game of overcharging based on a "comfort fee" and have the volume to back up this strategy. 

Obviously we are new to the game so we are learning as we go. 

You should gather professional opinions from real estate agent(s) and an appraiser – these are the people with their feet on the ground and their heads in the game.

Interesting idea about paying customers white listing the IP address, but wouldn't we have a hidden IP addresses via the VPN?

Get a report if there is one Change the locks Repair any damage If it’s really bad call your insurer As mentioned this is a common game loser tenants play and often it’s a lie to cover up something

Anyhow, I'm very eager to get into the game and to start my journey to have some passive income for more financial security.

Since they are not the best tenants, and you'll probably prefer replacing them, so what if they get annoyed at your "lack of customer service?"
