Broker preview is very similar to an office preview, except it is open to all the members of the local multiple listing service. It usually occurs within the first week your house is placed on the market, just after the office preview. However, there are lots of new listings to choose from, and not all the agents preview all the new listings each week. You may not get as many agents visiting your home as there were on the office preview.
Unless your agent "entices" them to come. This is where you could provide some help, if you are so inclined.
Though it may seem funny, nothing seems to attract a real estate agent like the offer of free food. So if your agent offers "free eats" at a broker preview, you are likely to get more visitors than if nothing is offered. Realize that many agents have been on this weekly circuit for years, so "boring" food does not really accomplish much. In other words, sandwiches supplied from the local grocery chain are not very enticing.
If you want to help your agent sell your home quickly, try and help them be creative and original in the choice of a culinary treat.
Of course, some agents will actually come to look at your house, too – whether food is offered or not.
