How Cottage Grove, Southsea prices moved
The chart tracks the median Cottage Grove, Southsea house price for every year with a recorded sale, from 1995 to 2024. 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 | £34,000 | £75,496 |
| 2000s | 10 | £86,750 | £158,033 |
| 2010s | 7 | £91,250 | £128,662 |
| 2020s | 4 | £92,500 | £94,511 |
The highest yearly median on record for Cottage Grove, Southsea is £235,000 in 2008; the lowest is £28,750 in 1995. Across the full 30-year record the cash median has moved from £28,750 to £92,500.
In 2026 money that first median is worth £63,839, so the real change over the whole record is +52.5% — about +1.47% 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: +10.8% in cash against -20.1% 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 Cottage Grove, Southsea values — no mix of property types can flatter the number.

Section 04
What sells here
The mix of property types explains a large part of any area's median. Cottage Grove, 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 | 195 | 76.2% | £68,000 | £11,000 – £240,000 |
| Terraced | 60 | 23.4% | £172,250 | £30,000 – £405,000 |
| Detached | 1 | 0.4% | £155,000 | £155,000 – £155,000 |
Section 06
Ownership and new build in Cottage Grove, Southsea
203 of the sales on record are leasehold and 53 freehold — 79.3% 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 £68,000 and the median freehold sale £225,000 — a gap of +230.9%. 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 | 203 | 79.3% | £68,000 |
| Freehold | 53 | 20.7% | £225,000 |
| New build | 5 | 2.0% | £129,995 |
| Existing home | 251 | 98.0% | £76,500 |
New builds sold for more than the median existing home — +69.9%. 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 19 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.

Against the median sale of £77,000 here, that rent is a gross yield of 21.30% a year. It is a measured figure rather than an assumption: a real local rent over a real local price, before any cost of ownership.

How Cottage Grove, Southsea compares
The median across the whole archive is £157,500. Cottage Grove, Southsea sits below that national figure — -51.1%.
Within Southsea the street ranks 479 of 486 by median price, and its median is below the town figure of £137,995 (-44.2%).
Where an EPC floor area could be matched to the sale, the median works out at £1,586 per square metre, across 72 of the 256 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 £11,000 to £405,000. 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.
Cottage Grove, 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 Cottage Grove, Southsea?
The median price paid in Cottage Grove, Southsea across every sale on the register is £77,000. 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 Cottage Grove, Southsea?
256 sales are on record for Cottage Grove, Southsea, the most recent completing on 23 Mar 2026. Every one is a completed transfer lodged with HM Land Registry, not an asking price or an estimate.
Have Cottage Grove, Southsea house prices actually risen?
In cash, the median rose +10.8% between 2013 and 2024. In 2026 money — that is, after inflation — the change is -20.1%. Both numbers are true; only the second one tells you whether buying here preserved value.
When were Cottage Grove, Southsea house prices at their highest?
The highest yearly median on record is £235,000, set in 2008. 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 Cottage Grove, Southsea?
£1,586 per square metre, from the 72 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 23 Mar 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.
