A postcode's reputation is priced in. Its value isn't.
So start with the brief. Budget, commute, schools, even how quiet the street is.
One brief, and England narrows to the postcodes worth your money.
Tighten the commute, and the keepers narrow further in seconds.
Down at street level, the strongest streets start to stand out.
Open one, and it shows its work. Sold prices, schools, crime, noise, broadband.
Keep the best-value few, export them, and scout where it actually counts.
Stop paying for the name. Find the value.
