SAN ANTONIO — Johnson Capital has arranged $6.7 million in mezzanine financing for the construction of the 225-unit Tobin Lofts, an off-campus student housing development serving the students of San Antonio College, which owns the $30 million development. Tobin Lofts will also feature a retail component. NRP Group has begun developing the property, which will open prior to the fall 2013 semester. Austin-based Campus Advantage will manage the community upon completion. Ron Davis of Johnson Capitals' Dallas office arranged the loan through a national private equity fund, while a separate $20 million construction loan was provided by a regional bank.
