The trend shows the general price tendency over the last 5 years, ignoring all month-to-month fluctuations where anomalies - typically over or underpriced property sales - can skew results. These monthly variations typically do not have any long-term relevance.

We have used linear regression method. The volume of sales in a month is used to put more weight on months with a larger number of properties sold. Additionally, weighting decreases the impact of months with low sales volumes as well as the most recent month - which may consist of incomplete data. Such months have a higher variation of average sale values which may conceal the underlying trend.

From a statistical perspective, we use the least squares method to fit the trend line and weights are equal to the volume of sales squared. The volume of sales is not shown explicitly in the above plot. Also note the time lag for HM Land Registry data to appear (typically 2 to 3 months).

Property Market Heat Gauge for Carmarthen - Nov 2025

Our Property Market Heat Gauge looks at how long properties in your postcode district have been on the open market before being changed to sold 'Subject to Contract' ('STC') or 'Under Offer' on Rightmove (the UK's leading property portal).

At 21 to 40 days, the broad evidence suggests that properties are selling reasonably quickly after being initially advertised and the market is reasonably healthy. If you are prepared to wait to up to 6 weeks, and you are sure that your property is priced realistically, you should get an offer within this timeframe.

Please note that this is not an indicator of how quickly property sales are taking to complete (i.e. to go through the whole conveyancing process). This measurement also does not take into account the risk of home sales falling through.
