If you’ve got a condo to unload, now’s the time.

Oahu condominium and townhome sales hit an 11-year high last month, with a new Realtors report showing the number of condo sales jumping 20 percent to 575 last month, compared with 481 a year earlier.

Indicating the high demand, there hadn’t been as many sales for a single month since August 2006; the all-time monthly record of 831 sales occurred in August 2005.

Price-wise, condos are holding fairly steady: the median price last month was $419,000, up 5 percent from a year earlier, but a tad lower than the record $425,000 set in July.

For prospective buyers, the time might also be right. The average 30-year fixed mortgage rate just dropped to 3.78 percent, which is down sharply from this year’s peak of 4.3 percent in March. Even better, if finances allow, is the 15-year mortgage rate, now averaging 3.08 percent.
