Drive Time vs. Distance: Why a Hospital '3 Miles Away' Can Take 30 Minutes
Pull up Google Maps. Pick two points in any city. The straight-line distance might be 2.8 miles. The driving directions? 22 minutes.
That gap — between how far something is and how long it takes to get there — is one of the most overlooked numbers in home buying.
The geometry problem
Hospitals don't float above your house. They sit on the other side of rivers, highways, railroad tracks, and neighborhoods with 25 mph speed limits.
A few real scenarios that stretch drive time far beyond distance:
- The river divide. You're on one side, the hospital is on the other. There are two bridges within 5 miles. At rush hour, both are backed up. Your "3-mile" hospital just became a 35-minute drive.
- The highway barrier. A major freeway runs between your neighborhood and the nearest ER. There's one overpass in a 2-mile stretch. Your GPS will take you the long way around.
- The school zone gauntlet. Three elementary schools between you and the hospital. During drop-off and pick-up, those 15 mph zones stack up.
- The one-way maze. Older city neighborhoods with one-way streets and no left turns. What looks direct on a map turns into a spiral.
None of this shows up on a Zillow listing. Most home-buying platforms show distance as a straight line — because it's computationally cheap, not because it's useful.
What "close" actually means
Here's a better framework. Forget distance. Think in minutes:
- Under 5 minutes: You can be there before panic sets in. This is the gold standard for families with young kids or elderly parents.
- 5-10 minutes: Solid. Manageable for urgent care, borderline for true emergencies.
- 10-20 minutes: Acceptable for routine visits. For emergencies, every minute counts.
- 20+ minutes: You should know this number before you sign. It might be fine — or it might be the thing you regret at 3 a.m.
Why most tools get this wrong
The real estate platforms have a structural reason for showing distance, not drive time. Distance is a one-time calculation between two coordinates. Drive time requires routing — which means querying a mapping service, accounting for traffic, and handling road network data that changes constantly.
It's harder to do. So most platforms don't.
But the difference between "2.1 miles" and "24 minutes" is the difference between "this is fine" and "I need to think about this." That's the number that matters when you're making a half-million-dollar decision about where your family lives.

Paste any Zillow, Redfin, or Realtor.com link into FindHomeFit. It pulls the address and shows you real drive times to every hospital in range — not the straight-line guesswork.
