Collin Central Appraisal District has levied a $24-million assessment against the six-story office building, built in 2006 on 6.4 acres at 2701 Dallas Pkwy. Market sources say the asset's 96% occupancy and age would fetch in the $150 per sf range, give or take $10 per sf to $15 per sf. With the two sources closely aligned, it's a fairly good bet that General Investment & Development Cos. of Boston shelled out $24 million or close to it for the latest piece for its Windsor Business Park portfolio, which picked up a 110,400-sf two-building portfolio in Houston's Bammel Business Park in September and Barton Oaks Plaza I in Austin in June.

The sale means Heady Investments, a Dallas-based developer, has now sold the last of its four buildings in Parkway Centre since work began in 1997. The park fronts the Dallas North Tollway and is tucked between the Shops of Willow Bend and Legacy Office Park. A Holliday Fenoglio Fowler LP team in Dallas sold the class A real estate.

Heady Investments has plans for a fifth office building on its land, but today's economic climate isn't conducive to project starts at this time. The developer had no comment about the latest sale and when, or if, it will build a fifth Parkway Centre.
