A complete guide to property investment in Carmarthen.

Last updated: 18 September 2025

Investment summary

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.

Should you invest in Carmarthen?

Opportunities

  • The private rented sector is relatively strong here, sitting in the 66th percentile for Britain, which means there are more rental properties and potentially higher tenant demand than in many other towns.
  • Investors can find a top rental yield of 4.0% in the highest-yielding district (SA31), and the median asking rent for a three-bedroom house is £1,195.
  • The median price per square foot is £195 per sq ft, which looks affordable compared to many other towns, especially for those looking at entry-level flats or family homes.

Risks

  • Liquidity is moderate, with annual sales at 176 and properties spending an average of 47 days, so investors may need patience when buying or selling.
  • Owner-occupation is in the 25th percentile, while social renting is in the 78th percentile, which could mean lower long-term stability for some tenancies and more exposure to regulatory changes.
  • The student population is in the 79th percentile, so void periods and tenant turnover could be an issue if you’re focused on student lets.

Outlook

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.
