I think this is a great idea and it would totally work but you have to be careful on how much furniture you place in the house. Some people like to see the big empty space when they buy a house because this makes them think they have plenty of room for their purposes.
But I must agree that the house would look nice with some furniture around which gives the buyers a better idea of how it is going to look like if they buy it and it makes it feel more like home...
