Raytheon Corp.'s new office campus in Richardson's $1.5 billion CityLine project has sold.

The three-building, 500,000-square-foot office complex on Bush Turnpike east of Plano Road cost almost $100 million to develop.

It's been purchased by Property Reserve Inc., a real estate and investment arm of the Church of Jesus Christ of Latter-day Saints.

Finished in early 2016, the four-story office campus houses almost 1,700 workers for Raytheon, the Massachusetts-based high-tech and defense manufacturer.

The Mormon Church bought the Raytheon offices from Dallas-based developer KDC, which is developing the entire 186-acre CityLine mixed-use project.

Raytheon occupies the buildings on a long-term lease running through 2026.

Commercial real estate firm CBRE marketed the buildings for sale by KDC. Terms of the deal were not disclosed. CBRE's John Alvarado, Gary Carr, Eric Mackey, Robert Hill and Pete VanAmburgh brokered the deal.

KDC paid off a $76.6 million construction loan on the property at the time of sale, Collin County deed records show.

With the Raytheon campus sale, KDC has now sold both of the major office projects it built at CityLine.

In November, KDC sold the four-tower State Farm Insurance campus at CityLine for $825 million to a partnership of Houston-based Transwestern Investment Group and a South Korean investor.

CityLine is one of the largest and most successful real estate projects in North Texas.

Along with the offices for State Farm and Raytheon, the development includes retail, restaurants, a hotel and hundreds of new apartments.

Raytheon campus buyer Property Reserve is based in Salt Lake City and owns real estate all over the country.

In the Dallas area, the investor has apartments in Las Colinas and Plano and industrial buildings in Carrollton.
