We’ve sold lots of UK properties and have never had to pay an agent more than 1.5% commission although some try to ask for 1.75-2%. I think this is one of the factors for the UK’s more lively property markets and of course the undersupply in the UK.
Transaction costs have to be factored in to buying and selling. 🙄
I really think there is much better value for money though in America, much better and larger properties for a lot less but they have restricted access unless you have a job an American can’t fill.
