A complete guide to property investment in Carmarthen.
Last updated: 18 September 2025
Carmarthen is a market town that tends to fly under the radar, but the numbers reveal a quietly resilient property market. The average rental yield sits at 4.1%, and capital growth over the past year has changed by 3.8%, with a three-year change of 7.3%. The annualised growth over three years clocks in at 2.4%, hinting at steady, if unspectacular, momentum. Affordability is one of Carmarthen’s calling cards, with a price-to-income ratio of 3.8 and a rent-to-income ratio of 20.2%, making it more accessible than many other parts of the country.

Looking ahead, Carmarthen’s market seems likely to keep moving at a steady, measured pace. The recent capital growth of 3.8% and annualised three-year figure of 2.4% suggest there’s no sign of overheating, but also little risk of a sharp correction. With a median achieved price sitting £4,000 (the typical achieved discount) below asking, buyers have some negotiating room, which helps keep things grounded.
Affordability remains a bright spot, as both sale and rent prices for typical properties such as three-bedroom houses (£260,000 and £1,195) and two-bedroom flats (£125,000) are accessible by national standards. All in all, I expect Carmarthen to appeal to investors looking for a balanced, predictable market rather than a rollercoaster ride.
