According to the Mortgage Bankers Association’s Weekly Applications Survey, demand for mortgage applications fell 4.1 percent last week from the week before. But though there was another increase in average mortgage rates, the decline was not seen as solely a reaction to higher rates. In fact, the drop was seen, at least partially, as a response to volatility in the stock market last week. Joel Kan, an MBA economist, told CNBC he still expects activity to grow as we enter the spring season. “Refinance activity is continuing along a floor, while the drop in purchase may be related to short term stock market jitters,” Kan said. “We still expect activity to pick up as we make our way into early spring.” Spring is traditionally the season when the housing market heats up and potential buyers start looking for homes to buy. This year, the spring buying season is expected to be particularly busy, with some saying home buyers are even trying to get a jump on competition by hitting the market earlier than usual. The MBA’s weekly survey has been conducted since 1990 and covers 75 percent of all retail residential mortgage applications. More here.
