KSI Management Corp., of Vienna, will be showing off its $6.2 million worth of renovations on the former Loudoun House, which previously was one of the county's few subsidized housing complexes.

Leesburg officials, prospective residents and community leaders were invited today to tour the 248-unit complex on Plaza Street. KSI spent $25,000 on each unit during the last eight months, painting them and replacing appliances, carpet, tiling and light fixtures, said Kim Andreadis, a marketing director at KSI.

The swimming pool also was redone, and more lighting was added to the parking areas. A fitness center was put in at the complex, which has been renamed Mayfair Commons. Half the apartments are still undergoing renovations, which KSI officials expect to be completed by mid-winter or early spring.

"People drive by, and they can't believe how it looks so different," Andreadis said.

The two- and three-bedroom apartments in the complex will rent at market rates. The average rent for an 824-square-foot, two bedroom, one bathroom apartment will be $795 a month. A 944-square-foot, three bedroom with one bathroom will be $895 a month.

Former residents can return if they can pay full rent or have rent-subsidy vouchers to cover what they cannot pay. Managers at the complex said nine families, including one family that used to live in the building, have moved in. Twenty-five more families are scheduled to move in before the end of the year, said the property's manager, Nguyen Banks.

Loudoun House, which was built during the 1970s, had become run-down and plagued by crime in recent years. KSI officials bought the complex last fall and worked with county housing officials to relocate residents. Many of the residents were elderly, and many had several relatives as their neighbors in the complex.

Most of the residents moved to other apartments in the county, but about 60 families moved out of Loudoun altogether to find affordable housing, said Cindy Mester, director of the county's housing services.

Although Leesburg officials and neighbors welcomed the complex's transformation, many residents were upset at being forced to leave.

Mester said the opening of Mayfair Commons comes at a time when the county desperately needs to find affordable housing for about 600 families who remain on a waiting list to receive assistance. Because some former Loudoun House residents moved out of the county, money became available to help about 130 waiting families, Mester said. The county also received additional federal money to help families.

"It's the first time in quite a while that we've got people not waiting for two to three years for help," Mester said.

Naomy Sorto, 23, lived in Loudoun House two years ago with her husband and two children, and they moved back in September. Sorto said she liked living in the complex because it was close to her job at the Roy Rogers on Route 7 and her children's day-care center.

"When we first moved back, we didn't even recognize the place," she said, as she carried groceries to her apartment one recent afternoon. "Look at the sidewalk. It's new pavement. Now everything is bright, new and so much better."
