The average flat price in London has risen by a massive 67 per cent over the past 10 years, new figures show.
Flats are the strongest performers and preferred property type in London - whilst semi-detached family homes are the top choice in the south east as a whole.
Semi-detached houses have risen in price by 45 per cent across the region, according to the Halifax data.
The bank found the average price of a flat has increased by £730 a month over the past decade.
Halifax housing economist Martin Ellis said: "First-time buyers have switched to some extent away from flats, reflecting their large price increases, towards semi-detached homes over the last decade."
However there is less choice in the London market, as flats make up around half of property sales.
Halifax think much of the reason for "ballooning" flat prices is down to the London market - where the average flat costs £370,281 compared to a national average of £233,424.
