Rate on 30-year mortgage ticks up to 4%.

Freddie Mac stated that the rate on the 30-year loan ticked up to 4 percent from 3.99 percent this past week. Six weeks ago, it dropped to a record low of 3.94 percent, according to the National Bureau of Economic Research .

The average rate on the 15-year fixed mortgage rose to 3.31 percent from 3.30 percent. Six weeks ago, it hit a record low of 3.26 percent.

But cheap mortgage rates have done little to boost home sales or refinancing. Rates have been below 5 percent for all but two weeks this year. Yet this year could be the worst for home sales in 14 years.  Mortgage applications fell 10 percent this week from the previous week, according to the Mortgage Bankers Association.
