The Dangers of Overvaluing...
It is understandable that you want to achieve the highest price for your property, so it is very tempting to ask just that little bit more. Unfortunately, some less scrupulous agents understand this only too well and will deliberately over-value your property to impress you and win your business. However, if you put your home on the market at too high a price, it will just sit there, unsold, while other more sensibly priced properties fly off the shelves.
In the end you may have to reduce your asking price to a more realistic level and will have missed out on the initial surge of buyer interest that greets each new property.
Remember, the longer your home is on the market, the harder it becomes to stimulate buyer interest.
