Buyer's Choosing Vacant Homes

In reviewing the numbers, I am seeing a trend with buyers and vacant homes. While 41%of the homes for sale today are vacant, 51% of the Pending homes are vacant and 45% of the sold and closed homes are vacant. Thus buyers are choosing vacant homes at a greater rate than of those occupied and that trend is increasing.
Why???
In short, regardless of why the home is vacant, those sellers are more motivated than occupied property sellers. That is it, short and simple!
