How Mariners Way, Seaham prices moved
The chart tracks the median Mariners Way, Seaham house price for every year with a recorded sale, from 2012 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 |
|---|---|---|---|
| 2010s | 6 | £124,300 | £175,263 |
| 2020s | 1 | £168,000 | £171,652 |
The highest yearly median on record for Mariners Way, Seaham is £168,000 in 2024; the lowest is £107,475 in 2017. Across the full 13-year record the cash median has moved from £119,950 to £168,000.
In 2026 money that first median is worth £179,163, so the real change over the whole record is -1.3% — about -0.11% 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: +6.4% in cash against -23.2% 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.

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 Mariners Way, Seaham 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. Mariners Way, Seaham 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 |
|---|---|---|---|---|
| Semi-detached | 39 | 41.1% | £158,950 | £110,000 – £225,000 |
| Terraced | 22 | 23.2% | £123,000 | £110,000 – £231,000 |
| Flat or maisonette | 20 | 21.1% | £75,250 | £68,000 – £92,000 |
| Detached | 14 | 14.7% | £175,000 | £136,465 – £249,950 |
Section 06
Ownership and new build in Mariners Way, Seaham
84 of the sales on record are leasehold and 11 freehold — 88.4% 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 £136,233 and the median freehold sale £185,000 — a gap of +35.8%. 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 | 84 | 88.4% | £136,233 |
| Freehold | 11 | 11.6% | £185,000 |
| New build | 44 | 46.3% | £141,227 |
| Existing home | 51 | 53.7% | £135,000 |
New builds sold for more than the median existing home — +4.6%. 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 5 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.

Living in Mariners Way, Seaham
Every certificate carries an energy efficiency band as well as a floor area. Across County Durham, 45.4% of 308,749 certificates sit in bands A to C, and 3.5% in F or G — the bands that cost the most to heat and are hardest to mortgage.
| Energy band | Certificates | Share |
|---|---|---|
| A | 1,955 | 0.6% |

The Office for National Statistics puts the mean private rent in County Durham at £641 a month as of Jun 2026 — £450 for a one-bedroom home and £683 for three bedrooms.
Against the median sale of £140,000 here, that rent is a gross yield of 5.49% 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.
Police forces publish every recorded street-level crime. Within a mile of the centre of SR7, 150 crimes were recorded in Jun 2026: 48 violent, 4 burglary, 5 vehicle-related and 46 anti-social behaviour. The median postcode district in this archive recorded 167 in the same month, so this one is about typical.
Against the 522,068 residents the 2021 census counted in County Durham, that is 0.29 recorded crimes per thousand people in the month. The count covers a mile around the district centre while the population covers the whole council, so read the rate as an order of magnitude rather than a precise figure.
A count is not a rate. A district with shops and a station records more crime than a residential one of the same size, because more people pass through it. Read this next to the median, not on its own.
Section 08
The neighbourhood around Mariners Way, Seaham
The 2021 census counted 522,068 residents in County Durham across 234,764 households. 62.8% of those households own their home and 37.1% rent — a split the sold record cannot show, because only owners appear in it.
11 state and independent schools have a SR7 postcode: 9 primary, 1 nursery, 1 secondary. Catchment areas do not follow postcodes, so treat this as what is nearby rather than what a child would be offered.

How Mariners Way, Seaham compares
The median across the whole archive is £157,500. Mariners Way, Seaham sits below that national figure — -11.1%.
Within Seaham the street ranks 79 of 432 by median price, and its median is above the town figure of £84,950 (+64.8%).
Where an EPC floor area could be matched to the sale, the median works out at £1,964 per square metre, across 25 of the 95 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 £68,000 to £249,950. 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.
Mariners Way, Seaham sits in County Durham, in the North East.
The Office for National Statistics puts the median home in County Durham at 4.3 times median local earnings of £32,945 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 Mariners Way, Seaham?
The median price paid in Mariners Way, Seaham across every sale on the register is £140,000. 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 Mariners Way, Seaham?
95 sales are on record for Mariners Way, Seaham, the most recent completing on 31 Mar 2026. Every one is a completed transfer lodged with HM Land Registry, not an asking price or an estimate.
Have Mariners Way, Seaham house prices actually risen?
In cash, the median rose +6.4% between 2013 and 2024. In 2026 money — that is, after inflation — the change is -23.2%. Both numbers are true; only the second one tells you whether buying here preserved value.
When were Mariners Way, Seaham house prices at their highest?
The highest yearly median on record is £168,000, set in 2024. 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 Mariners Way, Seaham?
£1,964 per square metre, from the 25 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 31 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.
