A Durham-based real estate company has raised $12.5 million in equity as part of its acquisition of some Cary office buildings, according to a filing with the Securities and Exchange Commission.

The Dilweg Cos., a commercial real estate investment firm, filed a Form D on Jan. 19, stating it has raised its total offering of $12.5 million through two investors.

The company announced in a release last week that it acquired the Regency Lakeview office space in Cary from Intercontinental Real Estate Corp.

Anthony Dilweg, Dilweg’s chief executive officer, plans to invest more than $4 million to improve the buildings’ operating systems, parking, common areas and tenant amenities, according to the press release.

Dilweg graduated from Duke University in 1989 and spent three years in the NFL as a quarterback. He entered the commercial real estate business as a broker in 1993 and founded the firm in 1999.

Companies relying on a Reg D exemption do not have to register their offering of securities with the SEC, but they must first file what’s known as a Form D electronically with the SEC after they first sell their securities.
