This tactic is two-fold. First, by stashing any valuables and/or collectibles you have, you don’t give would-be thieves a chance to steal your things. People who steal come in all shapes and sizes. From the child who puts a small trinket in his pocket to a couple disguising themselves as prospective homebuyers, anyone can make off with your things at any time. Second, getting rid of valuable and personal items declutters the home and makes it seem less personal, both of which are positives when trying to sell a home. By removing your own items, you allow a potential buyer to visualize his/her own belongings in the space.
