You’re relocating to a place with home security devices
A new home may come with an existing security system. All the devices function well, are installed in the correct areas, and are ready to go. In this instance, just pick up the phone to call and start a new service contract. A Vivint professional will still come to your home to ensure there are no compatibility issues, and they may offer suggestions on where you should replace bad outdated components. It's a fast appointment, and you can get your 24/7 monitoring set up without worrying about any new devices -- unless you get some new devices.
The outgoing owners can give an existing Vivint contract to your family for a one-time set-up fee to make your life a snap. If the previous owners are moving to an apartment complex or retirement community, you keeping the security contract may be an addendum of the sale.
You want to move and bring your old equipment with you
You may want to take your favorite smart devices with you to a new home when you move. Luckily, it's fairly simple to transfer, as modern smart devices are plug and play. You can uninstall each alarm or camera yourself or contact a Vivint expert to come and dismantle the system. Then a pro will hang the same devices -- and any smart devices you need to add -- in your new house. And your home security contract will remain the same.
