Berkshire takes sole control of MF1 and the seller's lending bench

Berkshire Residential Investments has entered a definitive agreement to acquire Limekiln's 50 percent interest in MF1, the multifamily mortgage lender the two launched as a 50/50 joint venture in 2018, and once the deal closes the venture will run as a wholly owned Berkshire subsidiary. Scott Waynebern, the Limekiln founder who formed the platform, will stay on as chief executive of Limekiln while that firm builds a new commercial real estate strategy.

The platform being handed over is substantial: MF1 has originated $32 billion of multifamily loans since 2018, and the announcement describes it as the leading private-label multifamily mortgage lender and a leading issuer of commercial real estate collateralized loan obligations. No purchase price is disclosed, which leaves the roster as the visible part of the bargain, and it is a full one: Limekiln's origination, capital markets, servicing, and legal leaders all move to Berkshire.

The named moves run through the entire bench: Russ Avery becomes executive managing director for capital markets investment, Tom Keefe executive managing director and co-head of MF1, Michael Squires senior managing director and head of production, and Sandy Vergano executive managing director for legal, investments.

That the seller's operating bench transfers rather than disperses is the substance of the trade, because a private-label lender is a flow business whose margin lives in origination, securitization, and servicing — precisely where a joint venture partner's leverage sits. Berkshire's half was never the constraint; Limekiln's was the second signature on every credit call, on extensions, modifications, decisions to hold a position through a soft quarter, and buying it out converts a negotiated process into a decided one. Eight years is a long run for a 50/50 lending venture, and this is a plausible enough reason for this one to end.

Waynebern keeps the firm and gives up the platform, which is the cleanest read of where value now sits in private-label apartment credit: with the balance sheet that can carry a book across a cycle, not with the sponsor equity alongside it. PWD has argued that the refinancing wall is being rolled, not repriced, with extensions and structured solutions doing work that paydowns once did. If that holds, the servicing and capital markets desk is the asset, and as of closing it is Berkshire's outright.

Berkshire has wired the unit internally as well: Jon Pfeil, a partner, becomes chief investment officer of the Credit and Lending business and continues to report to partner and chief investment officer Eric Draeger; Carolyn Burgess continues as partner and chief credit officer; and John Roach takes executive managing director and co-head of MF1 alongside Keefe. The immediate test is issuance — whether a lender the announcement calls a leading CRE CLO issuer holds that cadence with one owner at the table instead of two.
