Two parts
Master key system.
I have one key for every main entrance and each unit. 1 key is way better than 10+
Mechanical screw to the side of the house lock boxes.
1 per unit and 1 for myself and people I send to do mx and repairs
For the unit lock box I give just that unit the code and explain to them that if they come home hammered and can’t find their keys I’m not coming to let them in. So in each unit box is 1 common entrance key and unit specific entrance key. It’s up to them to put back if they use it.
For my lock box I have 1 common entrance key and 1 per unit.
So example. I was in the outer banks and my tenants at one place said the fridge finally died as the freezer. The same week I had another unit call me to say the toilet finally took a crap literally.
So i called my local appliance company and ordered a new fridge to installed next day and paid over the phone. Tenants were not going to be home so I have them the code and they installed.
Same with plumber. He changed the toilet out and some minor piping.
All this was done while I was sitting on the beach drinking some Tito’s and tonic.
I’d say my third favorite system is electronic rent collection with cozy. I set back and collect. If they are late cozy auto fees them.
4th. Even though I live within almost walking distance of my properties it’s stated in my lease that all mx request are to be done via email . It also states that without photos and a video request will not be answered.
Then I just refer to my first favorite system and send over my people and give them the code.
