Sold House Prices in M3

Figures use HM Land Registry Price Paid Data, standard sales only - HM Land Registry's "category A". That excludes repossessions and other sales under a power of sale, buy-to-lets identifiable by a mortgage, sales to companies and other non-private buyers, and properties classed as "Other". We also ignore entries under £1,000. Auctions are not excluded: a normal auction sale between a private buyer and seller is a standard sale and is counted here. HM Land Registry only began flagging these categories in October 2013, so almost every sale before then is counted as standard. Price Paid Data also leaves out sales never lodged for registration and transfers not for value - right-to-buy discounts, gifts, divorce transfers and compulsory purchases. Land Registry records some towns under two spellings that differ only in punctuation, such as ST. ALBANS and ST ALBANS; we treat those as one town. England and Wales only; HM Land Registry publishes with a 1-2 month lag.

Average price

The arithmetic mean of every standard full-value sale in the M3 district, all property types and all years since 1995 combined. Spanning decades, it typically sits below current values - see the year-by-year trend for the recent level.

Typical sold price (median)

The middle recorded sale price - half of recorded sales were below this and half above. Less swayed by one-off extreme sales than the mean, which is why the headline, the stats bar and the trend chart lead with it. The headline "typical sold price" is the median over the stated recent window (12, 24 or 36 months - shown next to the figure), not all years. The headline window median, and the price-distribution chart drawn from the same sales, needs at least 30 standard sales in that window - with fewer, no median is stated. A single year or a filtered set needs at least 3 recorded sales.

Total sales

A straight count of the standard sales recorded in the district, with the dates of the first and most recent.

Lowest / highest sale

The single lowest and highest individual sale prices recorded in the district in any year - two transactions, not a typical range.

Trend (% change)

We compare the median sold price in this district's earliest year with at least 10 recorded sales against its most recent complete such year - a median-on-median comparison, so a handful of extreme sales cannot move it. Years with fewer than 10 sales are skipped. We count only years that have had time to settle: never the current calendar year, and not the year before it until our data reaches March, because registrations are still arriving.

Year-on-year change

Each column in the yearly-change panel compares one year's median sold price with the previous year's median. Years where either year has fewer than 10 recorded sales are omitted, as is the incomplete final year - registrations for it are still arriving.

Price distribution

How many standard sales fell in each price band in the 24 months to Sep 2026 (window selectable above the chart; it ends at the latest recorded sale, not today). Bands are sized to the local spread; the lowest and highest bands are open-ended and hold the cheapest and dearest sales - up to the outer 5% at each end. "Typical" is the median - half of sales were below it and half above.

Price bands over time

Each column splits one year's standard sales across fixed price bands chosen from the district's own all-time distribution, so sales migrating up through unchanged bands is the story the chart shows. Years with fewer than 10 sales are gaps; the current year is flagged year to date.

Sold again recently

We precompute the 20 homes in the M3 district with the largest percentage difference between their earliest and most recent recorded sale price, then show those that sold again within the last 5 years. It is a recent slice of the biggest long-run risers, not a ranking of the last five years. The two prices are the first and last on record, so a home with more than two sales also sold in between at prices not shown. We leave out any address whose sales change property type or tenure, whose flat cannot be told apart from others in the same converted building, whose first sale was followed within two years by one at half as much again, or whose first sale sits far below what the area paid that year for that type of home - each a sign the earliest figure was not an ordinary open-market price. Each row is one property's history, not an area trend, and takes no account of extensions, renovation or condition.

Filtered stats bar

The count, median, mean, lowest and highest above the sales table describe the sales matching your current filters. With no filters set they summarise every standard full-value sale in the district, on the same basis as the headline stats above; once filters are applied they are recomputed from the individual sale records - the same records the filtered table and the CSV download draw on. Counts taken from precomputed area totals and counts computed live can differ by a handful of very recent sales whose registrations are still being folded in. With fewer than 3 matching sales no median is shown; the lowest and highest are then the actual individual prices.

Street averages

Each street average is the mean of that street's standard sales across all years. Streets with very few sales can look unusually high or low.

Street price rankings

Ranked among the 30 streets with the most sales in M3 - not every street in the district - by the mean of all their standard sales (category A, £1,000 or more) since 1995, whatever year those sales happened. A street that mostly sold recently will rank above an identical street that mostly sold in the 1990s - an era-mix effect, not a like-for-like comparison of what the streets are worth today.

Property-type mix

Share of standard sales by property type across the M3 district. Any new-build figure compares the average new-build price with the average existing-home price, weighted by number of sales.

Instant estimate

An automated estimate from nearby Land Registry sold prices adjusted for market trends - not a formal valuation. A local agent's valuation will be more accurate.

Change since previous sale

Where a sale row shows "up/down X% since {year}", that compares the sale price with the most recent earlier standard sale (category A, £1,000 or more) of the same property - not an area trend. Rows in buildings split into flats with no flat number recorded are not paired, because the earlier sale may be a different flat.
