For the best-value cottages, head to Kent via the A20, A21 and M25. The village of Eynsford, 18 miles from London, has a river, a church and an old castle. A two-up, two-down period property there costs about £250,000. Nearby Shoreham is also attractive, and towards Sevenoaks are Sundridge and Westerham, both delightful villages on the A25. Local estate agents include Lane Fox in Sevenoaks (01732 459900) and Ward Hunt in Eynsford (01322 862844).
