If you are relying on the valuer to value your property that you are thinking of buying, don’t buy. Do your homework, study the market more, until you feel you know much more than the valuer about your target market. Then make that commitment.
How true? I think valuer can only indicate the general price of property in the area or at least be relatively acurate to that extend. Beyond that you have to check the individual traits of the property. For example, to some people the property facing direction is important. Other factors are the address number, lot number, history of the property, tenant next door and suitability for its intended purpose.
Even properties that are side by side have vast different in prices due to the factors above. Key to pick a good investment is to know what the market wants.
