1000watt have an excellent post that emphasises the point of agents being open and not hiding information. It comes down to asking whether 'you' would want this information before buying a house and the answer is always going to be yes. Hiding information from buyers is akin to a second hand car salesman not mentioning that the car is in fact two crashed cars glued together.
1000watt make the point that the Internet can provide a plethora of information that is useful when buying a house, but it is even easier than that. Simply taking 50+ pictures of all rooms (not just the one the agent thinks looks nice) is easy. Take pictures of outside space, local amenities, anything that may be of interest. I may visit a property because I have seen a picture of a lovely little deli in the village, or it is explained to me that the house is next door to a football stadium, I may love football or may hate it. Either way, I want to know.
I have been banging on about a blog for every property for some time and this is a perfect example of where agents can easily make a difference.
In this current climate, you need to stand out, so stand out for telling the truth and providing information that the buyer actually needs.
