A typical Mill Hill home sells for about £640,000. That figure is an average of two different buyers. Flats go for well under half a million. Detached houses go for well over a million. Most of the market is families paying three-quarters of a million for a semi with a garden, and the flats are the cheap way in.
The Land Registry recorded 212 sales in the year to mid-May 2026, with a middle price of about £642,500. Split by type, the 69 flats went for around £435,000, the 37 terraced houses about £690,000, the 68 semis about £727,500 and the 38 detached houses about £1,267,500. Semis and flats sold in near-equal numbers, and they are the two ends of the ordinary market here. The detached house is a separate conversation with a separate mortgage adviser.
The official UK House Price Index for the area recorded an average price of about £590,600 in May 2026, down about 4% on a year earlier. Flats did worse, down about 6% over the same twelve months. That is a published fall, and a fall of that size is real money on a £435,000 flat. It is also just the last year's movement, and nothing in it says which way the next year goes.
Council tax is set high by the housing stock. Band D is the most common band, and only about 6% of homes sit in the two cheapest bands, A and B. Barnet charges about £2,130 a year at Band D, the bill most readers can hold up against their own. Cheap bands here are mostly flats, and there are not many of them.
Renting costs about £1,930 a month on average across the London Borough of Barnet as a whole, as of April 2026, up about 4% on the year. That is a mean from the Office for National Statistics' rent index for the whole borough, so it covers far more than this one district. By size, the Barnet average runs to about £1,490 for a one-bed, £1,840 for a two-bed, £2,230 for a three-bed and £3,170 for four bedrooms or more. A four-bed rented here costs about the same each month as some people's whole holiday.
Local household income is about £78,400, a gross figure before tax, modelled by the Office for National Statistics for the financial year to March 2023 and averaged across the area. Set beside a typical sale price of £642,500, that is a decent income buying into an expensive market, and the gap gets closed by savings, equity from a previous home or help from family. Gross income is the version on the payslip header, and the mortgage is paid from the line at the bottom.
Price per square metre gives a fairer comparison than the headline. Across the sales that could be matched to an energy certificate's floor area, about 71% of them, the middle price was about £6,640 per square metre, and the typical home behind that figure measured about 121 square metres. A good check on any Mill Hill asking price is the floor area on its energy certificate, because a big interwar semi and a cramped one carry the same label on the listing.
The homes are bigger than London buyers tend to expect. At the 2021 census about 12% of households had one bedroom, 29% two, 28% three and 31% four or more. Nearly a third of the place is four-bedroom houses, which tells you who it was built for and who still competes for it. Buyers hoping for a starter three-bed on a modest budget will find the families got there first and stayed.
Mill Hill is an expensive place to buy, and on value it rates below average: the prices only make sense if the space and the setting are exactly what you were going to pay for anyway.
