A new speed of sale tool has revealed that it’s taking an average of 18.45 weeks to sell a property across the SA postcode area in South West Wales.
Updated monthly, the latest dataset analysed over 721 property sales across the region between March 2024 and March 2025.
Properties were selling the fastest in Llanelli (SA15), Milford Haven (SA73) and Ammanford (SA18) adopting a minimum number of 10 property sales in a given area.
In the top 10 areas homes took 114.10 days (16.30 weeks) to sell on average.
The statistics track the moment a property is listed to the point it’s marked as officially ‘sold’ at the HM Land Registry.

Ruban Selvanayagam of Property Solvers commented: “While Swansea’s sale times remain in line with historical trends, there are encouraging signs that greater adoption of tech-driven efficiencies by industry stakeholders will help reduce transaction lengths. A key example is improving the accessibility and transparency of property-related data, making transactions more seamless.”
The co-founder of the sell house fast company concludes: “it’s also worth noting that many buyers have been pushing for their transactions to complete before 1st April given the reintroduction of the 2% Stamp Duty Land Tax (SDLT) band.”
