The Federal Reserve’s half-point cut on Tuesday could provide support for a slumping housing market. The Fed Funds rate affects a range of consumer loans, including home equity and mortgages. Lower mortgage rates would add to the number of home buyers able to afford to make purchases, increasing demand for properties and buoying home prices. Buyers generally care less about the actual purchase price than they do about the size of their payments. If rates drop, so will monthly debt obligations. But an important class of loans that might benefit from the big cut: the high-ticket home mortgages known as non-conforming or jumbo loans. These loans have no guaranteed secondary market because they exceed the $417,000 cap and Freddie Mac and Fannie Mae will not buy them.
