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 Isgraig, Porthmadog 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. Isgraig, Porthmadog 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 |
|---|---|---|---|---|
| Terraced | 17 | 100.0% | £76,000 | £18,750 – £130,000 |
Section 06
Ownership and new build in Isgraig, Porthmadog
0 of the sales on record are leasehold and 17 freehold — 0.0% 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.
| Category | Sales | Share | Median paid |
|---|---|---|---|
| Leasehold | 0 | 0.0% | — |
| Freehold | 17 | 100.0% | £76,000 |
A further 1 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.
Section 09
How Isgraig, Porthmadog compares
The median across the whole archive is £157,500. Isgraig, Porthmadog sits below that national figure — -51.7%.
Within Porthmadog the street ranks 61 of 70 by median price, and its median is below the town figure of £126,500 (-39.9%).
No EPC floor areas could be matched to these sales, so no price per square metre is published here. An estimate would be a guess, and the archive does not publish guesses.
The full range on record runs from £18,750 to £130,000. 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.
