Essex homes bought new resell £20,000 behind their neighbours

Research by ValuQ: we matched 30,701 Essex homes that were bought new from a developer and later resold, against 251,797 homes in the same districts bought second-hand, to find out what happens to the new-build premium when the owner comes to sell.

An Essex home bought new from a developer grows 10.8 log points less than an identical second-hand purchase in the same district, of the same property type, bought in the same year and sold in the same year. In cash, the typical gap is £20,272 of price growth that did not arrive. For people who bought new between 2020 and 2024, at a median price of £329,998, it is £25,171.

A new-build buyer in Essex pays 23.2 log points more than the going rate for a second-hand home of the same type in the same district and year, which is about 26 per cent. Some of that buys real things: a warranty, current building standards, a home nobody has lived in and a purchase with no chain in front of it. What the sold-price register shows is how much of that price difference is still there when the home changes hands again.

About half of the 10.8 point gap is not really about new builds at all. Anybody who buys above the going rate in their area gives some of it back later, whatever the age of the house. Measuring that effect on second-hand buyers alone and removing it leaves 5.8 points that belong to the home having been new.

The most useful part of this for a homeowner is what happens next. Following the same Essex homes into their second resale, where the owner bought second-hand and sold second-hand, the gap drops to 3.9 points. Split those owners by how old the home was when they bought it, and the picture is a premium being paid down in instalments.

By the time a home passes its tenth birthday, most of the effect has gone. The premium is not lost in one hit by the first owner. Each owner in turn pays a little less for newness than the one before, until there is nothing left to pay.

Thurrock stands out, and not only in Essex. Running the same method across the whole of England and Wales, on 825,928 matched sale pairs, the national gap is 9.9 points. Thurrock's 15.6 is the second widest of the 78 county-level areas with enough sales to measure, behind the City of Nottingham. Essex county as a whole sits at 9.9, right on the national figure.

Within five years of buying, 13.6 per cent of Essex new-build flat owners sold for less in cash than they paid, against 6.0 per cent of people who bought a second-hand flat. New-build houses are far steadier. For detached homes the cash-loss rate is 5.1 per cent, slightly below the 5.7 per cent for second-hand detached homes.

The sold-price register holds no floor area, no room count and no specification, so a new home and a second-hand home of the same type are not the same product. Part of that 26 per cent premium buys more house. The register also does not record developer incentives such as deposit contributions or part-exchange terms, which raise the recorded price without necessarily raising what a later buyer will pay. Both sit inside the measured gap and neither can be separated out with this data, which is why the paper reports the raw figure and the adjusted figure side by side.
