About £312,000 buys the middle of the market in Mullion. A detached house and a semi are not remotely in the same conversation here. Three bedrooms is the default unit. Flats are close to a rumour. What you are pricing in this village is a house with a bit of ground around it, which is why the cheap end and the expensive end sit so far apart.
The Land Registry recorded 35 sales in the year to early February 2026, at a median of £312,000. Broken out by type, that splits into detached homes at a median of £447,500 across 16 sales, terraces at £270,000 across eight, and semis at £230,000 across 11. Thirty-five sales in a year is a thin market, so a couple of unusual transactions move the middle around more than they would in a town. Read the by-type numbers before the headline one.
For direction, the published house price index for the area put the average price at about £279,700 as of May 2026, up 4% over the twelve months and up about 11% over five years. Flats went the other way over the same year, down by 0.4%, which is a fraction of a percent and worth treating as flat rather than falling. Neither figure is a forecast. They describe what has already happened to the index area, not what your offer should be next month.
Council tax lands on band D as the most common band, with 37% of dwellings sitting in bands A or B. The band D bill for the area runs to roughly £2,590 a year, which is the number most readers can hold against their current one and feel something about.
Renting is measured across Cornwall rather than the village itself, and the Office for National Statistics index gives a mean of about £1,000 a month, not a median of advertised listings. By size, that county average works out at around £690 a month for a one-bedroom home, £880 for two bedrooms, £1,080 for three, and £1,510 for four or more. Mullion's own rental stock is small enough that the county shape is the only honest guide.
On affordability, modelled household income for the area was about £45,700 in the financial year to March 2023, and that is gross, before anything is deducted. Set that against a £312,000 median and the arithmetic is unforgiving in the way most of coastal Cornwall is unforgiving: the houses are priced for people arriving with money made somewhere else, and the income figure describes the people already living here. The terraced and semi ends of the market are where a local wage still gets a look in. The detached market is not aimed at it.
For the sales that can be matched to an energy certificate's floor area, which is 60% of them, the median works out at about £3,100 per square metre, with a typical matched home measuring 79 square metres. That is a reasonable yardstick for comparing two properties against each other, and a poor one for valuing any single house, because the 40% of sales without a matched floor area are not in it.
The bedroom mix explains why three-bedroom listings dominate what you will see: 47% of households occupy three bedrooms, 24% have four or more, 23% have two, and 6% have one. Downsizing inside the village is harder than it sounds, because the small stock everyone wants barely exists.
Value here is middling, and honestly so. You are paying a coastal premium for a house that is priced against buyers from elsewhere, and getting a genuinely wide spread between the modest end and the detached end, which is the only real bargaining room the village offers.
