- Three features actually help: a smart thermostat, a video doorbell, and a smart lock are cheap, familiar, and buyers like seeing them. Nothing else moves the needle much.
- Appraisers ignore gadgets: a $200 device is not a comparable-sales adjustment. Smart tech may help a home show and sell faster, but it rarely raises the appraised value.
- Full automation is a money loser: proprietary hubs, subscription-locked security, and camera setups create liability and buyer distrust, and most of the spend never comes back.
- Paint, flooring, and staging beat gadgets: if you have a limited budget before listing, spend it on the boring, high-return basics first.
- Reset every device before closing: transferred accounts, live cameras, and leftover app access are a security and disclosure problem, not a selling point.
Does smart home technology actually increase home value?
Short answer: a little, and only for a few features. The marketing around smart homes wants you to believe that wiring your house with connected gadgets adds thousands to your sale price. The honest version is narrower. A handful of cheap, familiar devices can make your home feel current and help it show well. Most of the rest is commodity electronics that a buyer will replace, ignore, or quietly rip out after closing.
Start with how common this stuff already is. According to Parks Associates, smart home device adoption increased fivefold in the past ten years to 45% of US Internet households. When nearly half of homes already have a connected device, having one is not a differentiator that commands a premium. It is table stakes.
Notice that last number. The number of devices in the average smart home device-owning household peaked at 8 during the pandemic era and has dropped to 6.2, due to new users. Adoption is widening, not deepening. The typical buyer is a mainstream person with a doorbell and a thermostat, not an enthusiast who dreams about your whole-home lighting scenes. Build your pre-listing plan around that buyer, not the marketing fantasy.
Why appraisers and buyers treat gadgets differently than you do
An appraiser values your home by comparing it to recent sales of similar properties, then adjusting for real differences: square footage, lot size, bedroom count, condition, permitted additions. A $199 video doorbell is not a line-item adjustment. There is no comparable-sales data that isolates the price effect of a smart lock, so appraisers do not credit it. If you want to understand what an appraiser is looking at, our guide on how to prepare for a home appraisal covers what actually matters.
Buyers behave differently. Smart features can influence the emotional side of a showing and how "move-in ready" a home feels, which affects speed of sale and sometimes the strength of an offer. But that is a soft, hard-to-measure effect, not a guaranteed dollar figure. Be skeptical of any source promising a fixed percentage bump. Many of the eye-popping "buyers will pay more" statistics circulating online come from device manufacturers and security companies, not neutral research, and they measure stated intent in a survey rather than money that changed hands at closing.
Reframe the goal: the right question before listing is not "what adds value?" but "what helps my home sell faster without costing me much or creating a problem at closing?" That short list is where smart tech can earn its keep.
The three smart features with real buyer appeal
These three share a profile: low cost, brand-familiar, easy to understand, and no subscription required to keep the basic function working. That is the whole formula.
Smart thermostat
The strongest of the three, because it does something measurable. ENERGY STAR reports that for a certified smart thermostat, on average, savings are approximately 8% of heating and cooling bills or $50 per year. That is the independently verified figure. You will see brands advertise 15% to 23%, but those come from company marketing, not third-party certification. A thermostat runs $100 to $250 installed, looks modern on the wall, and gives a buyer a genuine energy story. It is one of the cleanest small upgrades you can make, and it pairs well with the broader case for green home upgrades that add value.
Video doorbell
Buyers recognize it instantly and associate it with security and convenience. It is now mainstream: Parks Associates data indicates about 45% of U.S. internet households own at least one core smart home device, and about 20% own a video doorbell. One caution worth knowing: video doorbells, which have seen slow but steady year-over-year growth for almost a decade, have dropped in adoption, and other categories such as smart cameras have also seen lower adoption. Demand is real but no longer surging. At $100 to $200, a doorbell is a reasonable staging-adjacent touch, not a value driver.
Smart lock
A keyless deadbolt reads as modern and solves a practical buyer worry (rekeying, lost keys, letting in a dog walker). It is inexpensive and, crucially, still works as an ordinary lock if a buyer never touches the app. That fallback matters. The features buyers reward are the ones that degrade gracefully into normal, dumb function when the smart part is ignored.
Not sure which upgrades are worth it in your market?
A top local agent knows exactly what buyers in your neighborhood pay for and what they shrug at. That single conversation can save you thousands in wasted pre-listing spending.

The smart features that create liability or turn buyers off
This is the part the gadget ads skip. Some smart investments do not just fail to add value. They actively complicate your sale.
- Proprietary automation hubs. A whole-home system built around one brand's hub locks a buyer into your ecosystem. If they use a different platform, it is dead weight they have to remove. The spend rarely comes back.
- Subscription-locked security systems. A device that stops recording or arming without a monthly fee is a bill you are handing the buyer, not a gift. Many buyers see it as a liability to cancel and replace.
- Indoor cameras and privacy worries. A buyer walking your home may wonder whether they are being recorded. Cameras raise questions about data, hacking, and who still has access. Some states also have recording-consent laws to consider.
- Fussy setups that will not transfer cleanly. Parks Associates found 52% of DIY users report setup or connectivity issues. If half of owners struggle with their own gear, imagine a buyer inheriting your half-configured system with your account still attached.
- Over-improvement. A home wired to the ceiling in a modest neighborhood does not appraise higher for it. This is a classic case of spending past the ceiling of what your comps support, covered in our guide on how not to over-improve your home.
The honest counterpoint: paint, flooring, and staging beat gadgets
Here is the section your device retailer will never write. If your pre-listing budget is limited, smart tech should be near the bottom of your list. The dollars almost always work harder on fresh paint, updated flooring, decluttering, and staging.
The National Association of Realtors 2025 Remodeling Impact Report makes the point bluntly. The projects that recover the most are unglamorous. The report revealed a new steel front door offers an estimated 100% return based on upfront cost. The broader takeaway from NAR is that for projects that recoup most or all of their cost, owners should think smaller, and swapping the front door for steel is likely to get the most bang for the buck. That is a door, not a hub.
Context on scale: Americans spent an estimated $603 billion on home remodeling projects in 2024. The winners in that spend are the basics that make a home feel clean, bright, and cared for. Our breakdown of low-cost home staging changes that increase your sale price and the fixes to do before listing are where your first dollars belong. Gadgets come after, if at all.
Scenario: $2,000 to spend before listing
Option A puts it all into a connected lighting system and a hub. Option B spends $1,200 on paint and a professional deep clean, $300 on a smart thermostat and video doorbell, and holds $500 for staging rentals. Option B will almost always show better in photos, appeal to more buyers, and leave you with less to explain at closing. The gadgets are the garnish, not the meal.
Spend your prep budget where it pays off
A high-performing listing agent will walk your home and tell you the two or three changes that actually move buyers, and the ones to skip. That advice is free when you interview agents.
Find a listing agentHow to hand off smart devices at closing without creating a problem
Whatever you leave behind, do it cleanly. A device still tied to your account is a security hole for the buyer and a headache for you. Before you list, decide what stays and what goes. Anything screwed or hardwired in (a thermostat, a deadbolt, a doorbell) is usually treated as a fixture that conveys, while portable plug-in gear is personal property. Our guide to what actually stays when you sell explains the line, and you should spell it out in the contract to avoid a dispute.
List what conveys
Write down every smart device staying with the home. Put the specifics in your listing and purchase agreement so there is no ambiguity about the thermostat or the doorbell.
Factory reset everything
Before closing, do a full factory reset on each device that stays. This wipes your settings and unlinks your account. Do not just delete the app.
Remove your account access
Log into each manufacturer app and remove the device and any shared users. Confirm your phone can no longer control the lock, camera, or doorbell.
Cancel or transfer subscriptions
End any monitoring or cloud-storage plan tied to your name. Never leave a recurring charge attached to a home you no longer own.
Leave the manuals and logins reset
Provide model numbers and reset instructions so the buyer can set up devices fresh under their own account.
Take the cameras down for showings. If you keep interior cameras during the listing period, disclose them and consider unplugging them while buyers tour. Recording visitors without notice can raise legal and trust issues, and it makes buyers uneasy.
A smart-spending game plan before you list
Put the pieces together into a simple order of operations. Spend on the basics first, add a couple of low-cost smart touches only if the budget allows, and avoid anything that locks a buyer into your ecosystem or your monthly bill.
| Upgrade | Typical cost | Worth it before selling? |
|---|---|---|
| Fresh paint and deep clean | $1,000 to $3,000 | Yes, do this first |
| Smart thermostat | $100 to $250 | Yes, low cost and real energy story |
| Video doorbell | $100 to $200 | Yes, familiar and appealing |
| Smart lock | $120 to $300 | Yes, works as a normal lock too |
| Interior smart cameras | $150 to $600 | No, privacy and trust concerns |
| Subscription security system | $300+ plus monthly | No, it is a bill you hand the buyer |
| Whole-home automation hub | $1,500 to $10,000+ | No, poor recovery and lock-in |
The pattern is consistent. The winners are cheap, standalone, and forgiving. The losers are expensive, interdependent, and demanding. Parks Associates projects the U.S. smart home market will keep growing, reaching $15 billion in sales revenue by 2029. That growth is good news for device makers. It does not mean loading your home with their products is good news for your net proceeds.
Frequently asked questions
Do smart home features increase my home's appraised value?
Generally no. Appraisers value your home against comparable sales, and there is no reliable data isolating what a $200 device adds. Smart features may help a home show well and sell faster, but they rarely change the appraised value.
Is a smart thermostat worth installing before I sell?
It is the best of the small smart upgrades. ENERGY STAR reports certified smart thermostats save about 8% of heating and cooling costs, or roughly $50 a year. At $100 to $250 installed, it looks modern and gives buyers a genuine energy-savings story.
Will a video doorbell help my home sell?
It can help at the margins. Video doorbells are mainstream, with roughly one in five internet households owning one per Parks Associates. Buyers recognize them and associate them with security. Treat it as a low-cost staging touch, not a value driver.
Should I install a whole-home automation system to attract buyers?
No. Proprietary hubs and full automation systems recover only a fraction of their cost, lock buyers into your ecosystem, and often get removed. If a buyer uses a different platform, your investment becomes their headache.
Do security cameras hurt or help when selling?
Interior cameras can hurt. They raise privacy and data concerns and make buyers uneasy during showings. Disclose any recording devices, consider unplugging interior cameras while buyers tour, and check your state's recording-consent rules.
What should I do with my smart devices at closing?
Factory reset every device that stays, remove your account and any shared users, and cancel or transfer subscriptions. A device still tied to your login is a security risk for the buyer and a loose end for you.
Is smart tech a better use of money than paint and staging?
Almost never. NAR's Remodeling Impact Report consistently shows small, basic projects like a new steel front door recover far more than gadgets. Spend on paint, flooring, cleaning, and staging first, then add a couple of cheap smart touches if the budget allows.
Do subscription-based security systems add resale value?
No. A system that requires a monthly fee to function is a recurring bill you are passing to the buyer, not a benefit. Many buyers plan to cancel and replace it, so it adds little and can even be a mild turnoff.
The bottom line
Smart home technology is not a resale silver bullet, and anyone selling you that story usually sells the devices too. The honest read: a smart thermostat, a video doorbell, and a smart lock are cheap, familiar, and mildly helpful for how your home shows. Everything past that (hubs, subscription security, interior cameras) tends to cost more than it returns and can complicate your sale. Put your money into paint, flooring, cleaning, and staging first. Add a gadget or two only if there is budget left, reset every device before closing, and lean on a strong local agent to tell you what your specific buyers actually pay for. That is how you spend smart, not just smart-home.
