South West London Property Market
Is it a buyers’ or sellers’ market?

Understanding whether the current property market favours buyers or sellers is key to making the right call. If you follow my regular property updates, you'll know one of the most reliable ways to assess the market is by looking at the percentage of homes marked as "Sold STC" or "Under Offer" compared to the total number of properties on the market.

Let's show that in practice. In this example, if there are 400 properties on the market in a location, and say 300 properties are for sale, fully available to buy, and the remaining 100 are under offer or sold. 100 as a percentage of 400 gives us a sales percentage of 25%. It is this percentage that strongly indicates the local property market temperature and who holds the upper hand, i.e. buyers or sellers (or somewhere between).

This percentage figure acts as a barometer for market conditions and can be analysed using this table:

·       Extreme Buyers' Market (0%-20%)
·       Buyers' Market (21%-29%)
·       Balanced Market (30%-40%)
·       Sellers' Market (41%-49%)
·       Hot Sellers' Market (50%-59%)
·       Extreme Sellers' Market (60%+)

As you can see the SW postcode has been slowly drifting downwards.

Yet within this, it does hide some interesting stats

Strong markets for sellers

SW14 is the standout: consistently the strongest performer across the board, still holding over 55% in August despite softening.

SW12 holding up well: despite a dip from the mid-40s earlier in the year, it remains one of the healthier seller markets at 36% in August.

SW19 remains steady: hovering close to 40% through the year, showing resilience compared to many neighbours.

SW6 shows stability: low 20s all year, but consistent, suggesting a reliable rather than volatile market.

Weakening or challenging spots

SW9 has taken the hardest hit: from 40% in January down to 27% by July and August, a sharp fall in confidence for sellers.

SW13 softening steadily: from over 50% in January down to just 34% in August, a significant cooling.

SW1 is flatlining: stuck around 13 to 16% all year, one of the hardest areas for sellers.

SW7 remains bottom of the table: barely scraping into double digits, a very challenging seller environment.

SW10 and SW5 continue to struggle: low teens throughout, offering little sign of life for sellers.

Markets to watch

SW16 and SW17 are wobbling: once mid-30s, they are slipping closer to the high 20s and low 30s.

SW18 holding its ground: one of the few that hasn’t dropped significantly, managing to stick in the mid-30s throughout.

SW20 stable in the mid-30s: not spectacular, but not falling apart either.
