Calendar years; a year’s median needs 5 sales of the type, so gaps are years with fewer.
Prices are as paid, not adjusted for inflation. Standard (category A) sales only; Land Registry adds a sale when it is registered, so the newest months fill in later.
New builds
5% of homes sold in the last 12 months were new builds
844 new homes have been sold in Carmarthen since 1995; the share peaked at 34% in 2012.
New-build share of sales
Calendar years with 10 or more sales, then the last 12 months.
New builds and tenure · 3 years
A new home sold for a median £300,000
against £190,000 for a home sold on, 58% more, over three years. New homes are often a different mix from the homes sold on, so part of the gap is size and type.
6% of sales were leasehold
Nearly every flat in England and Wales is leasehold; among houses, 2.2% sold leasehold in Carmarthen. A leasehold buyer owns the home for a fixed term and may pay ground rent and service charges; check the lease before you buy.
