For California short sales we are anticpating at another two or three years of strong activity,” said Jim Satterwhite, chief operating officer of National Quick Sale, a Jacksonville, Florida-based company that negotiates short sales on homes that are valued less than what they are mortgaged for.  Loan modification agreements, foreclosure prevention and bad credit refinancing continue to drive up the traffic for loan applications.  “Some mortgage refinance markets have seen better price stability, but they are not going up yet. But it will still be two or three more years before housing even starts to appreciate in some other markets,” he said.
