On Thursday, the government announced the leasehold system in England and Wales will be overhauled by the end of the current Parliament.
The service charges for Liam Mckinnon's leasehold flat in Bristol, managed by FirstPort, have tripled over five years to about £1,500 annually.
A leasehold is where homeowners do not own the land their property is built on but instead lease it from a landlord for as many as 999 years.
They are sometimes subject to service charges for the upkeep of the building.
The 35-year-old said he had "no other option" but to sell his two-bed flat because the charges were becoming unaffordable and he wanted to end dealings with the management company due to poor service.
