SO18 6TG is a more affordable market, with average prices 47% below the national average with essentially flat five-year movement of -9.0%. The median sits below the average, suggesting that a subset of higher-value sales pulls the mean upward — a pattern common in areas with mixed housing stock ranging from starter homes to luxury properties. Based on 60 registered HM Land Registry transactions across 19 years of data, these figures reflect actual completed sales rather than asking prices. Five-year growth compares average prices over 12-month windows; the most recent months may be slightly incomplete due to registration lag (sales can take 2–6 months to appear in the Land Registry). Note that this analysis draws on 60 transactions, which gives a directional picture but may not capture the full price range of this area.

Frequently Asked Questions

Why is my postcode missing?

A postcode may be missing when it has no recorded sales or too few registered HM Land Registry transactions to publish a useful page. Very recent completions can also be absent until registration and the next monthly data refresh.

How is the average price for this postcode calculated?

The average is the mean of registered residential sale prices available for this postcode in the Land Registry data. It is based on sold prices, not current valuations.

Are these asking prices?

No. These are completed sold prices recorded by HM Land Registry. They are not estate-agent asking prices, live listings or automated valuations.

Can I use this as a valuation?

No. The page is a research summary of historical sold prices. Use it to understand local evidence, then compare property condition, size, tenure, transaction type and professional valuation advice before making a decision.

Why can small postcode samples look unusual?

Some postcodes have only a small number of recorded sales. A few high or low value transactions can move the average, so the transaction count should be read alongside the price.
