``"It's clear that a lot of today's housing market recovery is being fueled by people putting their own money into homes. Some cash buying is part of a normal housing market, but we're at twice that normal rate. There are always some rich people, also buyers from abroad, but in a normal market the biggest single category would be retirees and empty-nesters who are down-sizing. Today, a lot of buyers are chasing what they view as the deal of a lifetime," said John Walsh, DataQuick president.''
