Also, Exchange Resources Inc., an escrow company, signed a three-year lease for 1,792 sf in a deal valued at $131,000. Exchange Resources represented itself.

In still another Shidler deal, Bradford Financial signed a five-year lease for 1,020 sf at 591 Camino de la Reina, Suite 928, in the Valley Corporate Center, formerly known as the Mission Valley Financial Center. Total consideration for the deal was $129,000. Burnham Real Estate Services represented both parties in the transaction.

Local market specialists have been saying for months that the Mission Valley office market is quickly becoming one of the most appealing in the county for owners enriched by the area's central location and high rents.

Mission Valley is enjoying an upswing in popularity among tenants, causing vacancies to plummet and rents to rise, a welcome development among building owners who so far have not fared as well as their North County colleagues in the county's recent office boom.

"Mission Valley's lack of available space combined with the lack of developable land, has helped drive up rental rates across the board to levels unseen in more than a decade," Richard Gonar, an office broker with Business Real Estate Brokerage Co., said last year.
