You can tell the difference the moment you walk through the front door. A home that’s been taken care of and one where things have been put off. Both might look fine in the listing photos. In person, one feels right. The other feels like work. Buyers know this. So do appraisers.
We’ve spent nearly five decades building and caring for large custom homes in the Valley. And the pattern is always the same: the ones that get looked after properly hold their value. The ones where maintenance gets pushed off quietly lose it. Not in one dramatic event. In a thousand small ones that add up while nobody’s watching.
What “We’ll Get to It Later” Actually Costs
These homes are complex. Commercial-grade HVAC, integrated automation, chiller systems, multiple pools, specialty finishes, all aging at the same time. And in Arizona, they’re aging faster than most owners realize. Temperature swings from freezing nights and snow at elevation to 122-degree summer peaks. Constant UV exposure. Hard water corroding plumbing and irrigation from the inside out. The desert doesn’t wait for a convenient time to cause problems.
The Appraisal Institute puts the cost of deferred maintenance at 10 to 30 percent of property value, depending on severity. For luxury homes, it lands at the higher end because the systems are more expensive, the expectations are higher, and buyers at this level are looking for anything that’s wrong. A $10,000 issue that gets ignored for two years can become a $50,000 to $150,000 repair. We’ve watched it happen. Water intrusion that started as a failed sealant joint. An HVAC compressor that was showing pressure trends months before it seized. A pool system that needed a $3,000 part and eventually required a $40,000 rebuild because nobody was reading the signs.
And that cost multiplies at the point of sale. Luxury buyers use inspections aggressively. Every unresolved issue becomes a negotiation weapon. Every deferred item gets priced into the offer, often at two or three times what it would have cost to fix proactively.
What Maintained Homes Sell For
The National Association of Realtors reports that homes in excellent condition sell for 5 to 10 percent more than comparable properties in average condition. They also spend less time on the market, which matters when carrying costs on a luxury property run high.
For luxury specifically, that premium gets bigger. Coldwell Banker and Sotheby’s put it at 10 to 20 percent for well-maintained luxury homes over similar properties that need updates. Zillow’s data tells the same story from the buyer’s side: listings described as “updated” or “like new” sell for a higher price per square foot, while properties showing deferred maintenance take price cuts before they even get an offer.
We see this play out in the homes we steward. Two of the properties under our care sold for record-setting dollars per square foot. They looked better five and ten years after construction than the day we finished building them. Maturing landscape. Systems running clean. Every finish holding up because someone was paying attention the whole time. You can’t stage that at listing time. It’s years of accumulated care, and buyers can feel it the second they walk in.
What Buyers Are Really Paying For
A well-maintained home tells a buyer something specific. The systems work. There aren’t going to be surprises. Someone was here, consistently, paying attention to the things most owners don’t think about until something fails. Buyers pay a premium for that because it takes risk off the table. And the people buying homes at this level are professionals at evaluating risk. They do it for a living. They can feel when a property has been genuinely cared for, and they will pay more for that confidence.
IBISWorld and McKinsey data on preventive maintenance in high-value assets backs this up from the operational side: proactive management reduces long-term costs by 12 to 18 percent annually and extends system life by 20 to 40 percent. But the bigger number is what shows up in the sale price. Years of consistent attention show up across an entire property, in the mechanical systems, the finishes, the landscape, everywhere. That’s what sets price-per-square-foot records. And it’s what lets an owner enjoy their home without wondering what’s quietly going wrong while they’re away.
The most expensive decision a homeowner makes is the decision to deal with things later. Later is when small problems become big ones, and when the gap between what a property is worth and what it sells for starts moving in the wrong direction.
