Does permanent lighting actually increase home value?

What our numbers actually say

We are not appraisers and we do not print Thraxel prices in a blog post, but we do track our own projects. Across residential installs from 2023 to 2025, homes carrying a permanent system appraised 3 to 7 percent above what comparable un-lit homes on the same street tended to draw.

That range is wide on purpose. A colonial with six zones of roofline running warm white behaves differently than a ranch with one zone over the garage. Treat the figure as a planning tool, not a promise your appraiser will sign.

We started tracking this internally because clients kept asking whether the install would show up on paper, not just in how the house felt at night. The 3 to 7 percent range is our best honest answer, built from real jobs rather than a marketing estimate.

Why a lit house appraises differently at all

Appraisers weigh condition and finish alongside comparable sales. A roofline traced in clean, color-matched track reads as a finished exterior the same way new gutters or a fresh paint job does. It signals upkeep even before anyone opens the front door.

There is also a timing effect. Permanent lighting shows a house at its best during a showing window that seasonal decor cannot touch: any evening, any month, without anyone hauling out C9 strands first. Buyers who tour after work see the house the way it will actually look most nights.

Comparable-sale appraisals also lean on curb photos taken by the appraiser during the visit. A house photographed with a clean, lit roofline in the file simply looks different in that report than one photographed as a dark rectangle at dusk.

The honest caveats

A lighting system will not offset a bad roof, a cracked foundation, or a listing priced above the neighborhood. It is a finishing touch on a house that is already sound, not a fix for one that is not.

Our figures come from a small, regional sample of Thraxel jobs, not a national study. A comparable Erie, PA colonial with 312 feet of roofline lit across six zones appraised about 42,000 dollars higher than its pre-install baseline, but that single job is an example, not a formula you can apply to your own square footage.

We also cannot separate lighting from everything else a homeowner did around the same time, a repainted door, cleaned-up landscaping, a new mailbox. Appraisals respond to the whole exterior, and lighting is one piece of that picture, not the entire story.

How this plays out across different home styles

A brick colonial with a long, visible roofline tends to show the effect more clearly than a split-level tucked behind mature trees, simply because more of the lit track is visible from the street or a comparable-sale photo.

Ranch homes with shorter rooflines still benefit, just at a smaller scale, since fewer linear feet of track means a smaller upfront project and a correspondingly smaller finish-quality shift for an appraiser to notice.

Homes already carrying strong curb appeal in daylight, mature landscaping, updated siding, tend to pair especially well with lighting, since the appraiser's overall condition impression was already trending positive before the lighting went in.

What the system actually adds to a listing

The install itself is individually addressable RGBWW pixels tucked into aluminum track color-matched to your trim, invisible in daylight and controllable from the Thraxel Lighting app the second the sun goes down. It has cleared every HOA board it has been presented to so far.

For a seller specifically, that means a listing photo shoot at twilight, a showing at 7 p.m. that still looks finished, and a talking point for the agent that costs the buyer nothing to maintain since it runs on roughly 52.80 dollars a year in electricity for a typical setup.

The same track and pixel system covers landscape beds, columns and a front walk beyond just the roofline, so the appraisal-relevant finish upgrade is not limited to the peak of the house alone if a homeowner wants broader coverage.

• 3-7% average appraisal lift in Thraxel's 2023-2025 tracking, directional only
• One Erie colonial example: 312 ft of roofline, 6 zones, about $42K higher
• Runs on real-time app control, no seasonal setup before a showing

Questions worth asking your agent first

Ask whether recent comparable sales on your street included any lit exteriors and how the agent thinks buyers reacted during evening showings, if any happened. Agents who work a lot of evening appointments in your area tend to have an opinion worth hearing.

Ask about your specific listing timeline against typical Thraxel scheduling windows, since a rushed install the week before photos is a different conversation than one planned months in advance with room to spare.

Finally, ask what a formal appraiser in your county actually weighs during a walkthrough. Some rely more heavily on strict comparable-sale math, others give more room to condition and finish. That answer shapes how much a lighting upgrade is likely to matter for your specific appraisal.

Should you install before you list?

If you are staying more than a season, install now and enjoy it. If you are listing within weeks, weigh the timeline against install scheduling and whether your exterior work, like a re-roof, is finished first.

Either way, the figures in this post are a starting point for a conversation, not a substitute for a licensed appraiser's opinion on your specific property, your specific comparables, and your specific market that week.
