Commission Rates in HK, can be flexible depending on the price of the boat.
Generally around 10%.
There are various ways. Both parties, the Seller and Buyer are required to split the commissions.
Or sometimes one party is paying the whole lot. It is basically the same thing.
Some buyers do want the sellers to pay commission, and vice versa. Either way it is added in the price.
The best practice is to confirm the commission and it’s structure with the broker. And Let it be transparent.
A good boat broker who has been in business for long term, will openly tell you of the commissions. If the Buyers or sellers think it is very high.
They should beware of brokers who charge very low commissions, but end up keeping a bigger difference during negotiations.
