In real estate, buyers and sellers have traditionally focused on visible factors like price, location, and appearance, while overlooking a critical dimension: how well a home actually performs its core functions. The industry’s long-standing blind spot has left consumers with little insight into a property’s efficiency, safety, and operating costs—factors that directly affect both quality of life and long-term value.
Tim Stanislaus, Senior Vice President of Business Development at Pearl, saw this gap clearly during his nearly five years building Zillow’s Premier Agent business. “Home buyers, home sellers, and lenders were largely transacting based on what they can see about a home—its price, its size, its location, its layout, curb appeal, features,” he says. “But what they can’t see is how the home actually performs the job of being a home: protecting health and safety, maintaining comfort, controlling operating costs, withstanding extreme weather, managing energy, maintaining value.”
This disconnect between what is visible and how a home actually functions creates problems throughout the real estate process. Buyers often underestimate the true cost of ownership, making decisions without a clear understanding of future utility bills or maintenance needs. Homeowners base upgrades on perceived resale value, not on measurable improvements in comfort or efficiency. Sellers struggle to highlight investments in solar panels, insulation, or HVAC systems when buyers have no way to evaluate their impact.
A New Way to Measure Home Performance
Pearl aims to address this problem with a standardized rating system that quantifies home performance in five key areas: safety, comfort, operations, resilience, and energy—collectively called the Pearl SCORE ™. The Pearl SCORE translates technical building data into a single, intuitive number from one to 1,000 and is searchable for any single family home in the U.S. on the Pear Home Performance Registry ™.
“For decades, experts in building science have measured performance in technical units—BTUs, R-values, air changes per hour, kilowatt hours, SEER ratings,” Stanislaus explains. “Those metrics are precise but inaccessible to most people. Most people don’t know what they mean, so real estate agents can’t easily communicate them, and appraisers rarely know how to value them.”
The Pearl SCORE ™ simplifies this complexity. For example, in the safety category, it measures how well a home protects occupants from hazards such as air pollution, radon, lead, and mold, using data on ventilation, airflow, and HVAC systems. It also factors in local environmental risks, making the score relevant to the home’s specific location.
Why Performance Matters Now
Recent market conditions have made home performance more relevant than ever. Affordability has reached near-record lows, with mortgage rates remaining high, and insurance premiums up by as much as 58% since 2018. Electricity and other utility costs continue to rise.
“Homeowners are feeling squeezed from all sides, and particularly buyers—very specifically, first-time buyers—are really struggling with this affordability challenge,” Stanislaus says. “What people are really looking for is predictability and value.”
As operating costs and risks increase, efficient, well-maintained homes become more attractive. They cost less to run, are easier to insure, and are more resilient to climate and energy price swings. However, until recently, these attributes remained largely hidden in real estate transactions, with buyers and sellers relying on guesswork or incomplete information.
Making Performance Data Public
To address this information gap, Pearl has launched a national public registry containing performance profiles for all 92 million single-family homes in the United States. The Pearl Home
Performance Registry ™, available at pearlscore.com, allows anyone to look up a property’s Pearl SCORE by entering an address. Homeowners can then claim their property to access detailed insights and update or correct information that may be missing from public records.
“You can think of this as being very analogous to a FICO credit rating score for a consumer,” Stanislaus says. “You have a credit rating based on all available information about you in the public domain, and your credit score impacts how much you can borrow, at what rate, whether you’re eligible for insurance. Your home has a very similar profile.”
Pearl SCORE compiles data from information in the public domain, such as property listing data and permit data—the same information that underwriters, insurers, and mortgage companies use to assess value and risk. By making this data accessible to homeowners, buyers, and agents, Pearl SCORE aims to make home performance a standard part of the real estate conversation.
Technology Adoption in a Demanding Industry
Stanislaus’s experience working with real estate professionals highlights why some technologies succeed while others fail. Agents are inundated with tools and platforms, so new solutions must be easy to understand and fit seamlessly into existing workflows.
“Agents are constantly bombarded with solutions and tools,” he says. “Those that succeed are intuitive, easy to understand, easy to pick up, easy to use.”
Integration is key. The most effective technologies provide relevant information within the systems agents already use, rather than requiring them to juggle separate applications. Tools that help agents deliver deeper, more actionable insights stand out, especially as consumers have become more knowledgeable and expect more from their real estate advisors.
“The everyday consumer is more educated today than they ever have been,” Stanislaus observes. “What really allows agents to win with their clients are tools that help consumers cut through all the noise and get to the ‘so what’ as quickly as possible.”
As transaction volumes decline and industry pressures increase due to commission scrutiny and regulatory changes, agents are relying on technology to deliver consistent, high-quality client experiences. Stanislaus emphasizes that clearly communicating value is now essential. “Agents need to be able to communicate their value very clearly and upfront to their clients in order to win business and maintain their sphere of influence,” he says. “The use of technology is one of the most important ways agents can continue to provide deep insights and maintain close client relationships.”
A Shift Toward Performance-Based Real Estate
The integration of home performance data into real estate transactions marks a significant change in the industry. By making performance visible and comparable, Pearl enables more informed decisions by buyers, sellers, and agents.
For real estate professionals, this provides a new way to differentiate their services. Instead of focusing only on surface features like finishes or landscaping, agents can now explain how investments in efficiency, safety, and resilience translate into comfort, lower operating costs, and long-term value for the homeowner.
As affordability challenges persist and climate-related risks become more prominent, the ability to quantify and communicate home performance is becoming a key advantage. The launch of Pearl Home Performance Registry™ makes it possible for buyers to see beyond appearances and for sellers to highlight meaningful improvements.
Moving from appearance-based to performance-based evaluation could address some of the market’s most urgent problems. Buyers gain a clearer picture of total ownership costs, while sellers have a new incentive to invest in upgrades that deliver measurable benefits. This approach promises to bring greater transparency, predictability, and value to the entire real estate process—helping both consumers and professionals make better decisions in an increasingly complex market.
