Short answer: pull up the listing's Walk Score, Transit Score, and Bike Score — they're free, instant, and a decent first filter. Then go stand on the sidewalk and walk the route yourself, because the number is measuring something narrower than "is this a nice walk."

What Walk Score actually measures

Walk Score (now owned by Redfin, so it's baked right into most listings) scores an address from 0–100 based on how many amenities — grocery stores, restaurants, schools, parks, coffee shops — sit within roughly a 5-to-30-minute walk, weighted by distance, with closer amenities worth more. It also factors in population density and street design — block length, intersection density — as a rough proxy for how pedestrian-friendly the layout is. Its companions work the same way for other modes: Transit Score rates how well-served an address is by public transit (frequency and type of nearby routes), and Bike Score rates biking infrastructure and hill terrain. The general read: 90–100 is "Walker's Paradise," 70–89 "Very Walkable," 50–69 "Somewhat Walkable," under 50 means you're driving for basically everything.

The catch nobody puts on the listing page

Here's the part worth being honest about: Walk Score measures proximity, not quality. It's counting how many things are within a certain distance, not whether the walk to get there is actually pleasant or safe. A grocery store 0.4 miles away scores well whether you're strolling down a tree-lined block with sidewalks the whole way, or picking your way along a shoulderless road, crossing a four-lane arterial with no crosswalk, past a highway on-ramp. Same distance, wildly different walk. The score doesn't know the difference.

It also doesn't account for hills (outside of Bike Score's terrain factor), weather, lighting at night, sidewalk condition or whether sidewalks exist at all, how a crossing actually feels with cars doing 45 in a 35, or perceived safety. Urban planning researchers have flagged the same gap for years — Walk Score is a solid density/proximity index, and a mediocre substitute for "would a person reasonably choose to walk this."

None of that makes it useless. It's a fast, free, comparable-across-listings signal, and it's directionally right almost all of the time — a 92 is nearly always a genuinely walkable place, a 15 nearly always isn't. It's the middle scores, and the specific route to the one place you'll actually walk to weekly, where it can mislead you.

How to sanity-check it yourself

This one's simple and most buyers skip it: during a showing, actually walk the route to the nearest grocery store, park, or transit stop — not the route Walk Score assumes, the one you'd actually take. Notice whether there are sidewalks the whole way, whether you'd have to cross anything hairy, whether it's a walk you'd want to make with a stroller, in the dark, in January. Fifteen minutes on foot tells you more than the number does. If you can't walk it during the showing, at least trace it on Google Street View before you get too attached to a listing based on its score alone.

Why this is a real financial question, not just a lifestyle one

It's tempting to file walkability under "nice to have" next to granite countertops. The data says otherwise. A 2020 Redfin analysis of nearly 1 million home sales across 16 major metros found walkable homes sold for an average of 23.5% — about $77,700 — more than comparable car-dependent homes nearby, with big metro variation (Boston's premium ran to roughly $140,000; a few markets like Oakland actually skewed negative). An earlier Redfin study put a more granular number on it: each single point of Walk Score was worth up to $3,000 in home value, depending on the metro — dense coastal cities saw the biggest per-point bump, sprawling Sun Belt metros barely moved. On the demand side, the National Association of Realtors' 2023 Community and Transportation Preferences Survey found 90% of Gen Z and millennial respondents said they'd pay more to live somewhere walkable — a third said "a lot more."

Translation for this audience: walkability isn't just about whether you personally enjoy a stroll. In most markets it correlates with resale demand and appreciation, because a growing share of buyers — including whoever buys the place from you eventually — are actively screening for it. That's worth weighing even if you, personally, don't care.

How much you should actually weight it

This is genuinely a "depends on you" answer, and be suspicious of anyone who tells you walkability is objectively the right priority for every buyer. If you want to ditch a second car, don't want a daily commute by highway, or just like the idea of walking to a coffee shop instead of driving to one, weight it heavily — it's not a minor preference, it's closer to a load-bearing lifestyle decision, and the resale data backs up leaning into it. If you're fine driving everywhere, want more square footage or a bigger lot for the money, or care more about school district or a specific commute, it's entirely reasonable to deprioritize walkability and let a lower score save you money on the purchase price — you're not making a mistake, you're making a different trade. The score is a data point. What you actually do with your Tuesday evenings is the deciding factor.
