Fewer options exist on the Boston office market, and what is available is more expensive then previous quarters.  Combined with fewer concessions offered by landlords, local tenants are feeling the pinch.

From the Boston Globe:

Boston’s office market is hopping, according to reports issued by real estate brokerages Transwestern and Jones Lang LaSalle. Driven by strong employment gains and growing companies in need of additional space, rents are rising all across Greater Boston, up 7.6 percent in the last 12 months. Throughout Cambridge, there are just three vacant office spaces of 20,000 square feet or more on the market, and rents in Kendall Square are averaging above $70 per square foot. Along Route 128, vacancy rates are at record lows, while office rents along Interstate 495 are at seven-year highs.
