How Castle Road, Southsea prices moved
The chart tracks the median Castle Road, Southsea house price for every year with a recorded sale, from 1995 to 2025. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.
| Decade | Years with sales | Median paid | In today's money |
|---|---|---|---|
| 1990s | 5 | £45,000 | £99,921 |
| 2000s | 8 | £111,250 | £202,665 |
| 2010s | 6 | £179,000 | £252,390 |
| 2020s | 5 | £247,500 | £252,880 |
The highest yearly median on record for Castle Road, Southsea is £420,000 in 2020; the lowest is £38,027 in 1996. Across the full 31-year record the cash median has moved from £52,000 to £155,000.
In 2026 money that first median is worth £115,465, so the real change over the whole record is +37.2% — about +1.06% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.
Over the last decade alone the difference is stark: -14.9% in cash against -38.3% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

The most recent sales
Every row is a completed sale as lodged with HM Land Registry. The right-hand column restates the price in 2026 money, which is the only fair way to compare a sale from the 1990s with one from last year.

Homes that sold twice
These addresses appear in the register more than once, so the same bricks are being priced twice. That makes them the strongest evidence of what actually happened to Castle Road, Southsea values — no mix of property types can flatter the number.

What sells here
The mix of property types explains a large part of any area's median. Castle Road, Southsea is dominated by the type at the top of this table, so its overall median leans that way.
| Property type | Sales | Share | Median paid | Range |
|---|---|---|---|---|
| Flat or maisonette | 151 | 66.8% | £104,995 | £27,000 – £435,000 |
| Terraced | 62 | 27.4% | £237,000 | £38,027 – £699,950 |
| Semi-detached | 12 | 5.3% | £350,000 | £168,000 – £1,175,000 |
| Detached | 1 | 0.4% | £129,000 | £129,000 – £129,000 |
Section 06
Ownership and new build in Castle Road, Southsea
151 of the sales on record are leasehold and 75 freehold — 66.8% of the market. Tenure is not a detail: a leasehold flat and a freehold house are different assets, and mixing them into one median hides the difference.
The median leasehold sale is £104,995 and the median freehold sale £245,000 — a gap of +133.3%. Most of that gap is property type rather than tenure itself: leasehold here is largely flats, freehold largely houses.
| Category | Sales | Share | Median paid |
|---|---|---|---|
| Leasehold | 151 | 66.8% | £104,995 |
| Freehold | 75 | 33.2% | £245,000 |
| New build | 3 | 1.3% | £420,000 |
| Existing home | 223 | 98.7% | £126,000 |
New builds sold for more than the median existing home — +233.3%. A new-build premium is normal: the buyer gets a warranty and nothing to fix, and the price is set by a developer rather than negotiated between two households.
A further 18 transfers for this area are on the register but are left out of every figure above. HM Land Registry marks them as additional price paid entries: repossessions, buy-to-let portfolio moves, transfers between companies or family, and sales at a discount such as right to buy. They are real records but they are not open-market prices, and including them would drag the median somewhere no buyer ever paid.

How Castle Road, Southsea compares
The median across the whole archive is £157,500. Castle Road, Southsea sits below that national figure — -18.7%.
Within Southsea the street ranks 342 of 486 by median price, and its median is below the town figure of £137,995 (-7.2%).
Where an EPC floor area could be matched to the sale, the median works out at £2,084 per square metre, across 42 of the 226 sales on record. Price per square metre is the only figure that compares a two-bed flat with a four-bed house honestly.
The full range on record runs from £27,000 to £1,175,000. Extremes usually mean something unusual — a plot sold without a house on it, a transfer between family members, or a very large property — so the median is the number to trust.
Castle Road, Southsea sits in Portsmouth, in the South East.
The Office for National Statistics puts the median home in Portsmouth at 6.7 times median local earnings of £38,815 a year, measured to Sep 2025. Across England and Wales the same ratio is 7.6. That number, not the price alone, is what decides whether a place is within reach of the people who work in it.

Quick answers
Common questions about this data
What is the average house price in Castle Road, Southsea?
The median price paid in Castle Road, Southsea across every sale on the register is £128,000. The median is used rather than the mean because a handful of very large sales would otherwise drag the average away from what a typical buyer paid.
How many homes have sold in Castle Road, Southsea?
226 sales are on record for Castle Road, Southsea, the most recent completing on 1 May 2026. Every one is a completed transfer lodged with HM Land Registry, not an asking price or an estimate.
Have Castle Road, Southsea house prices actually risen?
In cash, the median rose -14.9% between 2015 and 2025. In 2026 money — that is, after inflation — the change is -38.3%. Both numbers are true; only the second one tells you whether buying here preserved value.
When were Castle Road, Southsea house prices at their highest?
The highest yearly median on record is £420,000, set in 2020. That is the cash figure; measured in 2026 money the peak may fall in a different year, because inflation reshapes the series.
What is the price per square metre in Castle Road, Southsea?
£2,084 per square metre, from the 42 sales where an EPC floor area could be matched to the address. Price per square metre strips out size, so a flat and a house can be compared on the same basis.
How current is this data?
The latest sale shown here completed on 1 May 2026. HM Land Registry publishes Price Paid Data monthly and a sale can take a month or two to appear after completion, so the most recent weeks are always incomplete.
