There is no single fee model
Buying agents commonly charge an initial activation fee or retainer, followed by a success fee when a purchase is secured. Some focused services use a fixed fee or a minimum total fee.
Scope changes the price
A complete search involves more work than negotiation on one property. Geography, travel, urgency, property type, number of viewings, complexity and the level of purchase support can all affect the quotation.
Understand what the percentage applies to
Where a percentage fee is used, the engagement should state whether it is calculated on the agreed purchase price, whether VAT applies and whether the initial payment is credited against the final fee.
Ask what happens if you do not buy
The agreement should explain cancellation rights, the treatment of the activation fee, any third party costs and whether work can pause if your circumstances change.
Compare value as well as cost
The relevant question is not only what the buying agent charges. It is whether the service can save time, reduce unsuitable viewings, improve the evidence available and strengthen the final buying decision.
