The Sage Score

Homes have many diverse features. But you may not ever see most of these when the homes are for sale. The Sage Score along with Livability Categories help you compare homes and their features giving you more knowledge about what the home offers.

The Sage Score is the only instant comprehensive score to compare and market properties more easily. It considers hundreds of features in a home and its surrounding community under 8 categories: energy; water; systems/appliances; interior finishes; construction; community/outdoors; technology; and utility information.

The Right Track Home
1 - 25

To save the money or save the planet? Yes, you can do both and this is a great place to start. Homes in this range have features which are better than the average resale home. Those features may include a combination of upgrades such as energy and water efficient fixtures, community features like walkability, or even a renewable energy source.

The Remarkable Home
26 - 50

A stand out in the marketplace with greater energy efficiency, quality construction, energy and water efficiency and maybe even renewable energy. Comfort, easy maintenance and lower ownership costs are often part of these homes.

The Top Notch Home
51 - 75

Like a strong cup of coffee, these properties pack a punch. These homes typically have a combination of renewable energy, sustainable materials and water and energy efficiencies to reduce your monthly costs and increase your comfort. They may also have a third party certification. Ownership is noticeably easier and less costly than a typical property.

Livability Categories

Not only should you know what those features are, but also know what it means for living in that home — is it more energy efficient, does it have lower utility costs, is it more comfortable, healthier and environmentally friendly?

Livability Categories provide more knowledge about the potential benefits of certain property features including the potential cost savings, eco and health benefits.
