After mortgage rates dropped in the U.S. for the second week in a row, borrowing costs hit their lowest rate yet for 2014. This week, the average rate shifted from 4.12% to 4.1% for a 30 year fixed mortgage. Although the percentage shift may be small, when added up over 30 years, even the smallest changes can greatly impact the cost of home ownership. A 30 year rate has not been this low since the end of October last year. 15 year mortgages also saw price reductions, slipping from 3.24% to 3.23% this month. The 30 year rate has been consistently declining since it had hit a two year high of 4.58% last August. Experts foresee the lower rates supporting and fostering home demand. July trends support these expert’s claims, as previously owned homes sold at an annualized rate of 5.15 million this July, up 2.4% from June. The longer the rates stay low, the more activity can be expected in the future of the US housing market.
