The single biggest mistake we hear about after the fact isn't picking the wrong town — it's picking a town based on the wrong visit. A great weekend trip and a livable town are not the same claim, and most vacations are engineered, on purpose, to make a place look better than it will feel on a random Tuesday in February.
A few adjustments that actually close the gap:
Go on a bad-weather day. Anyone can love a town in perfect sun. Visit during the season you're least excited about, not the one on the postcard.
Do your actual errands there. Find the grocery store, the pharmacy, the hardware store. A town's charm often lives downtown, but your life will mostly happen at the edges of it.
Talk to someone who moved there in the last two years, not someone who's lived there for thirty. Recent transplants remember the friction you're about to experience; longtime locals have forgotten it exists.
Sit in on something recurring — a farmers market, a town council meeting, a Sunday service. One-off events are curated. Recurring ones show you the town's actual rhythm.
Price groceries and services, not just real estate. Housing costs get all the research energy; the weekly cost of living is what you'll actually feel.
None of this replaces the quiz or the guides for narrowing down which kind of town fits your life. But once you've got a shortlist, how you visit matters almost as much as where.
