Your new house has a pre-existing security system
Many times after you buy a house, you’ll see that the old owners left a home security system. All the devices function well, are placed in the correct places, and are ready to go. In this example, all you may have to do is to call and start a new contract. A Vivint professional will still come out to make sure there are no integration issues, and they may offer ideas on an upgrade or two. It's a quick appointment, and you can get your 24/7 monitoring set up without worrying about any new components -- unless you make additions.
The outgoing homeowners can transfer an existing Vivint contract to you for a nominal set-up fee to make your life simpler. If the outgoing residents are downsizing to a condo 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 bring your old Vivint system with you to a new place when you move. That’s pretty easy to do, as modern components are plug and play. You can uninstall each device by yourself or use a professional expert to take down your devices. Then an expert will hang the same features -- and any new things you want -- in your new home. The home security contract will remain the same.
