The lettings and estate agent compared the difference in sold prices between leasehold and freehold property sales registered with the Land Registry over the last year.
Across the nation as a whole, a freehold home will set you back 10% more on average than a leasehold with an average sold price of £300,565 to £273,080.
When it comes to property type, the biggest premium paid is for a freehold terraced home, coming in at £242,902 for the average freehold, 53% more than the £158,675 paid for the average leasehold terraced house.
The freehold price premium for a detached or semi-detached home is currently 36% and 34% respectively, while flats are interestingly the only property type where the price paid for freehold is lower, -16% cheaper than the price paid for a leasehold.
The biggest premiums can predictably be found within the capital where the average freehold secures 31% more than a leasehold property. However, over the last year in the borough of Camden, the average price paid for a freehold hit nearly £2.6m, 205% more than the £848,262 paid for a leasehold home.
This freehold premium was also at its highest in Kensington and Chelsea (196%), Westminster (134%) and Islington (127%).
Outside of London, Powys was home to the highest freehold premium (126%), followed by Surrey (110%) and West Sussex (98%).
Marc von Grundherr, Director of Benham and Reeves, commented: “Freehold properties will always command a higher price due to the greater sense of security and ownership despite many leaseholds coming with a lifetime or more on the current lease but the extent of this premium is very much down to the length of a lease which can drastically impact price.
"Of course, this demand for freehold homes was no doubt intensified in the wake of the leasehold scandal a few years back and so it comes as no surprise that the freehold price premium paid by homebuyers in the last year has hit as high as 205% in some parts of London.
"However, if you do want to dodge the freehold house price premium, the figures show that a flat is the best investment and will see you pay less on average compared to leasehold flat.”
