MF1 Capital is jumping from the fast lane of short-term bridge lending into the more buttoned-up world of fixed-rate bonds, closing a $734 million bundled CMBS deal anchored by The Lightwell, a new Class A rental building in DUMBO. The transaction is the firm’s first commercial mortgage-backed securities offering and hints at a broader shift in how multifamily loans can be packaged for institutional buyers. For Brooklyn owners, it could open another path to long-term financing for stabilized, high-rent properties.
According to CoStar, the MF1 deal totals $734 million and bundles loans backed by The Lightwell at 218 Front Street. CoStar reports that this marks MF1’s first fixed-rate CMBS transaction after years of focusing on floating-rate bridge lending for multifamily sponsors.
StreetEasy shows The Lightwell as a 218-unit, seven-story rental building completed in 2024 at 218 Front St in the Vinegar Hill/DUMBO area. Listings highlight premium rents and a full slate of amenities consistent with Class A product, the kind of stabilized collateral that typically attracts conduit and large-loan CMBS investors.
MF1, a debt fund formed as a joint venture between Limekiln Real Estate and Berkshire Residential Investments, built its name on quick, high-leverage bridge loans, as reported by The Real Deal. That outlet has also chronicled MF1’s active securitization activity in recent years, a track record that helps set the stage for its move into packaging loans as fixed-rate securities.
Why MF1's Move Matters
Commercial mortgage-backed securities take pools of loans and turn them into rated, fixed-rate bonds for institutional investors, which can give borrowers longer-term, often non-recourse financing and a different risk profile than floating-rate bridge debt. That institutional structure can reduce monthly debt service for stabilized properties, as described by the Securities and Exchange Commission in its explanations of CMBS deal mechanics and investor protections.
Market Context
MF1’s shift comes at a shaky moment for the CMBS market. KBRA’s April 2026 loan-performance update shows delinquency and distress levels still running high, even as some pockets of new issuance creep back into the market. In that split environment, deals that bundle well-located, stabilized multifamily assets such as The Lightwell may draw solid investor interest, while loans backed by weaker property types continue to struggle.
For Brooklyn landlords, MF1’s CMBS entry could represent another route to permanent, fixed-rate financing if other non-bank lenders follow the same playbook. MF1 has not yet shared full details on investors or pricing; those specifics are expected to surface in trust documents and bond materials as the transaction is formally marketed and sold.
