What sells here
The mix of property types explains a large part of any area's median. William Street, Caernarfon 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 | 56 | 94.9% | £77,000 | £12,500 – £134,000 |
| Semi-detached | 3 | 5.1% | £110,000 | £40,000 – £117,000 |
Section 06
Ownership and new build in William Street, Caernarfon
0 of the sales on record are leasehold and 59 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 | 59 | 100.0% | £77,500 |
A further 2 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.

Every certificate carries an energy efficiency band as well as a floor area. Across Gwynedd, 26.3% of 59,374 certificates sit in bands A to C, and 20.7% in F or G — the bands that cost the most to heat and are hardest to mortgage.

The Office for National Statistics puts the mean private rent in Gwynedd at £719 a month as of Jun 2026 — £555 for a one-bedroom home and £798 for three bedrooms.
Against the median sale of £77,500 here, that rent is a gross yield of 11.13% 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.
No street-level crime was published for LL55 in Jun 2026. Several forces do not supply street-level data to police.uk, so this is a gap in the source rather than a crime-free month — and printing a zero would say something the data does not.

William Street, Caernarfon sits in Gwynedd, in Wales.
The Office for National Statistics puts the median home in Gwynedd at 5.9 times median local earnings of £32,697 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.
