Developed by Monument Realty seven years ago, Monument I sits off the Dulles Airport Access Road in Fairfax County. The seven-story building was originally home to E.Spire Communications Inc. and later housed other tech firms, but sat vacant for a year until ITT leased the entire structure in February. Capital Lease CEO Paul McDowell says the acquisition contributes to "the progress we are making in building a high-credit quality, geographically diverse portfolio of net lease assets which produce attractive risk-adjusted returns for our stockholders."
