The deal was valued at $20 million, said a person familiar with the terms who asked not to be identified because the price wasn’t announced. PropertyCapsule helps market commercial real estate. “This effectively doubles VTS’s retail footprint,” VTS Chief Executive Officer Nick Romito said last week in an interview. VTS and PropertyCapsule each manage about 2 billion square feet of retail properties, he said.
