By Trevor Damyan, Commercial Mortgage Broker at Commercial Lending Solutions

A $12 million ground-up multifamily construction loan in Brooklyn typically finances a 30 to 60 unit boutique multifamily project at total project cost of $20M to $30M including land, hard costs, soft costs, and reserves. Brooklyn ground-up faces specific regulatory and structural challenges including Local Law 97 carbon caps, 421-a / 485-x abatement structuring, Local Law 11 facade requirements, and HSTPA rent stabilization considerations. Most $12M Brooklyn ground-up loans fund through specialty bridge debt funds at 65 to 75 percent LTC, with permanent take-out via Fannie Mae or Freddie Mac at stabilization.
