Fed buyback

The housing market is red hot as low rates, shifting work conditions and a years supply of pent up saving have caused demand to exceed supply. Adding to the problem the Fed is buying back $40 billion dollars of mortgage backed securities every month. US homes hit an all time high value of $330,000. VA and first time home buyer loans are available with no money down and others may qualify based on circumstances. These Fed purchases keep rates low and maintains a steady flow of credit. This seems counter productive to some economist.
