This also tells me which circuits need to be split.On the front end it's a bit of work, but I seldom get breaker calls on the properties whose circuits I have attended to.I sometimes leave a lockbox for a contractor if I need to, or leave it unlocked. 

You simply unlock the door and go inside.

I applied for an SBA EIDL loan almost immediately after they announced it. A few days ago I got a note saying they still have my app and sit tight. I got a 2nd email yesterday saying they were going to process it, and...

permission to make _______ modification to the house/yard, notifying us that a rent payment will be late, notifying us that they are moving out early, storm damage, (tree fell on house) doorknob won't lock/unlock.

@Taylor Jones Exciting to see the tax benefits you've unlocked from utilizing a cost segregation study!

I know this is essentially unanswerable because if you have this figured out then you have unlocked the secret everyone in every industry is trying to figure out. 

On an empty house the water company will have the meter unlocked, but not in the open position.

So a benefit is selling and doing a 1031 to another state and unlocking all of that equity and not just partial to put to work.

So do you keep available units unlocked?

Chances are the water company just came up to the meter and unlocked their valve, then noticed their wasn't a gate valve on the house side of the meter, after 30 gallons was sent through the meter they shut off the water to ensure they didn't flood any area of the property and determined that you need a gate valve and that translated to "you need a plumber to bring the property up to code" rather than saying "you are missing a gate valve on the house side of the water meter, code requires it".
