Billionaire Thomas Dundon’s firm faces $98M foreclosure on Downtown Dallas office tower

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. Dallas-Fort Worth continues to absorb the largest multifamily delivery pipeline in the country. Industrial along the I-35 corridor is clearing at competitive basis, and selective office is finding bids at deep discounts to replacement. 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.
