Greater Boston & Southern NH · Office Market Intelligence
Thinking About Selling Your
Office Building?
Before You List, Know What Buyers Will Pay — and Why.
The Greater Boston office market is highly bifurcated — but the buyer who will pay the most for your building isn’t looking at the market average. They’re looking at your specific town, your tenant quality, your lease structure, and whether your zoning supports their highest and best use. That’s what we model before you list. Choose your county below for localized, data-driven market intelligence.

MANSARD Strategy
We Don't Start With a Listing.
We Start With Strategy.
Most owners make the decision to sell too late — or go to market before they fully understand their options. MANSARD was built to change that.
- Know what a 1031 exchange buyer, owner-user, investor, and developer will each pay for your building
- Understand your zoning rights and how they expand or limit your buyer pool
- Calculate your net proceeds after taxes, depreciation recapture, and closing costs — before you list
- Go to market from a position of strength — not desperation
88.9% of MANSARD's recent sales closed on-time and at the client's accepted offer price. That outcome is determined before the property ever goes live.
