Average new seller asking prices have fallen this month by 1.8% – the equivalent of £6,591 – according to Rightmove. 

This compares to an average drop over the previous ten years of 1.1% in November. This makes it the largest fall in prices at this time of year since 2012. 

The decade-high number of homes available for sale continues to put downwards pressure on prices, while concerns over how the upcoming Budget will impact personal finances and housing affordability are unsettling some potential movers, claims the portal. 

Both of these factors are compounding the seasonal slowdown in prices that we’d usually see in November, with the Christmas lull arriving early this year. 

With buyers more distracted than usual, sellers who have already come to market are reducing their asking prices by more than the norm, as they attempt to entice bargain-hunting buyers. Over a third (34%) of homes available for sale have had an asking price reduction, with the average size of price reduction being 7%. Both figures are the highest since February 2024. 

The number of sales agreed for homes priced over £2 million, which would be subject to the rumoured mansion tax, is down by 13% compared to the same period last year. 

Growing speculation that the government will look to increase taxes on these properties, accounting for around 1% of the market, has led to some buyers in this price band waiting to see what the Budget brings. The number of new sellers coming to market in this price bracket is also down by 9%, a larger drop than in lower-priced market sectors.

It’s a similar story for homes priced between £500,000 and £2 million, which would be impacted by rumoured stamp duty changes in England, and some also by capital gains tax on homes sold for over £1.5million. Sales agreed in this price range are down by 8% year-on-year, a smaller drop than the £2 million+ sector, but a larger decline than the overall average this month of a 5% year-on-year fall in agreed sales.

Meanwhile, homes priced under £500,000, accounting for approximately 75% of the market,  have proved more resilient, with movers more likely to be carrying on as normal. 

The number of sales agreed in this sector is down by only 4% compared to this time last year. While homes in this price bracket haven’t yet been the focus of any specific property tax rumours, the upcoming Budget is likely still causing some general jitters around how personal finances and affordability will be affected. 

Rightmove says it’s also important to note that this data for the full month of October is comparing with a strong month last year where sales activity was ramping up, particularly in the south of England, in anticipation of the stamp duty increases in England from April 2025. This is contributing to the downward year-on-year activity trends, but across the whole year to date the overall number of sales being agreed is still up by 4% on the same period in 2024.

As well as the forthcoming Budget, many would-be home-movers will have their eyes on the mortgage rate trend and how their affordability is affected. 

The average two-year fixed mortgage rate is currently 4.41%, which while down from 5.06% at this time last year, has been slower to fall during 2025 than many predicted. Though the decision to hold the Bank Rate in November rather than cut it will be disappointing to movers, there is still a good chance of a rate cut in December, which would be a welcome early Christmas present for movers.
