Craig Lloyd writing for How-To Geek:

Smarthome devices are expensive, and if you’ve decked out your entire house with all sorts of fun smarthome toys, that’s thousands of dollars of extra value added onto your house, which can make for a great negotiating tool when it comes time to sell.

I’m not planning to move, but have still thought about this whenever I install a new piece of gear in the house, such as my ecobee thermostats. I’ve always assumed that if it’s in the house when your house is being shown, that’s a fixture and your buyers are going to assume it’s part of the price unless you spell it out otherwise. I don’t practice real estate law, though. Regardless of the law, you BETTER spell this out pretty explicitly if for no other reason than you’re going to have ticked off buyers if they saw a house with fancy smart home gadgets that aren’t there come final walkthrough.
