Diamond’s Snowflake- and WeWork-Leased 306,000 SQFT Concar Campus Still on the Market in San Mateo, Seven Years After $320MM Buy
Why this matters
Office continues to trade in two distinct markets: trophy assets in walkable submarkets that are leasing at or near record rents, and commodity Class B and C buildings where the basis is still resetting. Underwriting on the latter has moved toward replacement-cost-minus, with credit underwriting now leaning on tenant covenant and remaining lease term rather than mark-to-market expectations. For LP-positioned capital, the read-through is that the bifurcation is now a structural feature of the sector, not a cycle to wait out.
