Gary, if viewing through an agent, first check to see if the property is listed with other agents because the price can differ wildly between agents, I mean sometimes over 100k on an average property.
If you settle on an agent and trust his advice, there are some good ones but word of mouth is the key, then ask him outright to tell what commission has been included in the price and prove it! A good agent should not baulk from this request.
However, as previously mentioned here, there are literally 1000’s of private sales but check their legality first.
Lastly, don’t use the agent’s recommended lawyer for conveyancing, get an independent one. 😉
