Domovita is a UK property portal. Sold prices here come from HM Land Registry and are free to search - no account, no sign-up.

Every standard-market sale HM Land Registry has recorded on Oldcastle Avenue, Guilsfield in the SY21 postcode district. Sales data to September 2026 (HM Land Registry), updated monthly. England and Wales coverage.

Across the wider SY21 district (not just this street), the typical (median) sold price is ↑ 446% between 1995 and 2025, median-on-medianCalculated across the wider SY21 postcode district, not this street alone (one street rarely has enough sales each year for a reliable trend). We compare the district's median sold price in its earliest year with at least 10 recorded sales against its most recent complete such year - a median-on-median comparison. 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. ↑ 7% over the 2 years to 2025 Note: the mix of homes sold changes over time, which also moves this comparison - see the by-type breakdown.

All 83 recorded standard sales on Oldcastle Avenue - one mark per sale, no averaging. The price axis starts at zero. Thin grey lines join sales of the same home - the one true like-for-like comparison in this data. The bars beneath count the sales in each year; zero-sale years are left blank. * 2026 is incomplete (to Sep - year to date). (HM Land Registry, England and Wales.) Each mark is one standard (HM Land Registry category-A) sale on Oldcastle Avenue: its position shows the completion date and the price actually paid. Colour is the property type; a square is a new build; a hollow mark is a leasehold sale. Grey connecting lines join consecutive sales of the same address. The bar panel beneath counts the sales in each calendar year - it is the sample size behind any impression the scatter gives. Nothing is averaged, smoothed or projected - and no estimate of today's value is implied.

Median sold price, indexed - 1995 = 100

Each point is the year's median divided by the 1995 figure (£43,500), so 200 means double the 1995 value in cash terms. Values are nominal. How we work this out

Median sold price per year in the wider SY21 district - half of recorded sales in each year were below the line. The dashed line is the average (mean). The price axis does not start at zero. * 2026 is incomplete (to Sep - year to date) and is excluded from the year-on-year panel. (Standard sales, HM Land Registry.)The line is the median sale price of standard sales in the wider SY21 district each year - half were below it; the dashed line is the mean. Years with few sales are drawn hollow or get no point. These are the prices of what happened to sell each year, not a like-for-like index. Full method
Sold price per year in the wider SY21 district. In years with fewer than 3 sales no median or average is published - with 1 or 2 sales the lowest and highest columns are the actual individual prices.

Property types in SY21

Each share is that property type's slice of all standard (HM Land Registry category-A) sales in SY21. The price beside it is the mean sale price for that type across all recorded years. The freehold/leasehold split and any new-build figure compare averages weighted by number of sales. Much of a "flat vs house" or leasehold gap is the property type itself, not a premium.
Detached 52% £209,418
Semi-detached 27% £119,538
Terraced 20% £100,738
Flat / Apartment 1% £61,808
Prices are the mean across all recorded years - a few expensive sales can pull an average upward.

98% freehold, 2% leasehold, across all recorded years. Comparing new-build and existing homes type by type (each type weighted by how many sales it has here), new builds sold for around 30% less, across all recorded years. New builds sell mostly in the years they were built, so part of that gap is when they sold, not only that they were new; the detail below compares within each type.

Tenure and new-build detail by type
TypeFreeholdNew-build vs existing
Detached 100% -35% for new build
Semi-detached 99% -29% for new build
Terraced 99% -2% for new build
Flat / Apartment 16% -33% for new build

New-build vs existing compares mean prices within the same type, so it is partly mix-adjusted - but it is not a like-for-like index.

Homes that sold more than once on Oldcastle AvenueEvery address on Oldcastle Avenue with two or more recorded standard (HM Land Registry category-A) sales, matched on the exact address so a sale can never be attributed to a neighbouring home. "Change" is the difference between consecutive sales of the same home. "Annualised" is the constant yearly rate that would grow the earlier price into the later one over the time between them (compound), and is only shown when the sales are at least two years apart (closer pairs show how long apart they were). These are historical facts about past sales - they are not an estimate of what any home is worth today.

A home selling twice is the cleanest price comparison the Land Registry data offers - the same bricks, years apart. 27 addresses here have sold more than once.
