Moving across country before your current home sells? You can’t rely on a cross-your-fingers approach to protecting your twin real-estate investments. As you forge a new life hundreds of miles away, you’ve got to make sure that vacant house is protected. The elements, neglect, mischief and criminal activity all can conspire to devalue your property during your absence, potentially costing you bigtime when a buyer bypasses your former abode for a better-maintained dwelling. You’ll need to prepare prior to your interstate move and remain attentive until a purchaser signs on the dotted line. While your vacant home needn’t be a 24-7 hub.
