According to research commissioned by Millgate Homes the perfect scent to sell a home is a mixture of white tea and fig.
(To date it has been traditional to brew up a pot of coffee, bake bread or put out freshly cut flowers when prospective buyers come to look round a home, and indeed the smell of baking bread and freshly brewed coffee can still be used to sell older properties, because they are associated with feeling homely and warm, but the scents of white tea and fig are better for new builds because they have fresh and clean designs.
I don’t even know what white tea smells like.)
