Houwzer, launched in 2015 and which provides discount brokerage services to consumers (such as a flat $5,000 listing fee to sellers), has acquired Trelora, a discount broker headquartered in Denver. Discount brokers have come and gone in the industry, and the promise remains big to those who attempt it. Philadelphia-based Houwzer has slowly gained traction over the years, while adding alternative financing services. It is showing promise as it continues to grow.
