Due in part to lackluster participation, the federal government is extending a program allowing homeowners with mortgages backed by Fannie Mae or Freddie Mac to refinance at lower rates.

The Home Affordable Refinance Program, or HARP, was supposed to expire at the end of this year.

But federal officials extended the initiative through 2015 so that more borrowers can take advantage of the chance to cut their interest rates and lower their mortgage payments. Published reports estimated that about 2.2 million people have refinanced their mortgages through the program since April 2009, short of the anticipated 4 million borrowers expected to use it.

To qualify, the mortgage must have been originated before 2009 and the owed amount must be more than 80 percent of the home’s appraised rate.

Tenant mix

The mixed-use Mixson community in North Charleston’s Park Circle area is gradually taking shape. In addition to construction of the Mixson Bath & Racquet Club, there’s an apartment development on the horizon.

Flats at Mixson, a 268 one- and two-bedroom complex, will begin preleasing this summer. The development by Atlanta-based Jamestown Properties will consist of 10 buildings and private garages flanking both sides of Mixson Avenue, officials said. The contemporary development includes modern kitchens with wide-plank flooring and Shaker-style cabinets.

Charleston-based multifamily giant Greystar will handle the leasing and property management, officials said.

Amenities at the Flats include a fitness center, pool, dog-wash station, club room, cafe, resident-designated parking and courtyards.
