About £289,000 for a typical sale, and that figure is a fiction the moment you look at what actually changed hands. The detached houses went for nearly half a million. The flats went for a quarter of that. Barely a dozen homes sold all year. The median here is not a price, it is an average of two different property markets that happen to share a postcode.
The Land Registry recorded 12 sales in the year to April 2026, at a median of £289,000. Split by type, the five detached sales came in at a median of £480,000 and the four flats at £121,000. That gap is the valley doing what valleys do: the substantial houses sit on the good ground with the view, the converted flats sit lower down and cheaper, and the middle of the market is thin enough that a single unusual sale would move the headline number. Twelve transactions is a small enough sample that any buyer treating £289,000 as the going rate for a family house is going to have an educational afternoon.
For a steadier read, the published house price index for the area puts the average at £280,000 as of May 2026, up 4% over the twelve months. Flats went the other way, down under half a percent over the same period, which is small enough to count as flat in every sense. Over five years the index is up 11%. None of that is a forecast, and none of it tells you what the house you are looking at will do.
Council tax is where Calstock gets cheap. Band A is the most common band, and 44% of dwellings sit in bands A or B. A band D bill runs to about £2,590 a year, which is the figure most readers can hold against their own bill, and most of the village is paying considerably less than that.
Renting is a Cornwall-wide picture rather than a Calstock one. The typical private rent across the Cornwall area is about £1,000 a month, taken as a mean from the Office for National Statistics price index rather than a median of advertised listings. By size across the same area, one-beds average £689 a month, two-beds £882, three-beds £1,078, and four-beds or larger £1,509. Nobody publishes a Calstock number, and anyone quoting you one has made it up.
On affordability, modelled gross household income for the area in the financial year to March 2023 was around £46,000 before tax. Set that against a £289,000 median and the arithmetic is tight but not absurd by the standards of coastal and river Cornwall, which is exactly the reputation Calstock has earned. What it will not do is buy you a detached house. The £480,000 end of this market is being funded by equity from somewhere else, and the flats at the bottom are what local money can actually reach.
The stock itself skews toward the family end. As of the 2021 census, 39% of households have three bedrooms, 28% have two, 24% have four or more, and 9% have one. That is a village of houses rather than starter flats, which explains both the price spread and why the small end of the market is so short of options.
For what you get, the money here is reasonable. Cornwall has plenty of places asking more for less scenery and worse council tax, and Calstock is not one of them. The catch is that the affordable half of the market is flats and the desirable half is not, and no amount of median-gazing bridges that.
