What my clients are saying

We hired Jim to help sell my brother's triplex. He had died with no insurance and the building had more debt than it's appraised value. Jim negotiated a large reductions in the debts which the estate could then pay off. Jim sold the property for the full asking price!

Josephine Boccelli, Philadelphia

Jim Helped us find the home of our dreams. We wanted to spend between $300,000 to $320,000. Jim found us a beautiful English Tudor. He negotiated a purchase of $320,000 from the listed $388,000! Jim has a great work ethic, is loaded with integrity and loves real estate. Jim is our realtor for life!

Tony and Peggy P, Radnor, PA

We hired Jim to sell an estate property on a busy corner and not in great condition. The first realtor gave up after six months. Jim sold the home in 38 days to a professional sports figure. We never thought we would receive more than $150,000 but got $200,000. Jim is very professional and a gentleman.

Passionate about helping people and a connector at heart, Jim is always happy to talk to you if you ever have a real estate related need or a question. And if he can’t help you, he will direct you to someone that can.

After starting his first construction company at 18, Jim worked as an industrial arts educator in inner city Philadelphia schools for 7 years and received a Masters in Education from Temple University.

In 1983, he started Jim Thornton Construction Company, which handled projects from multi-unit affordable housing developments in Denver, CO., to high-end residential and commercial projects in the Main Line and Philadelphia areas.

In 1993, Jim began working as a licensed real estate agent for Re/Max while managing his construction companies full-time. By his third year as a part-time agent, he achieved an annual sales volume of three million and has been a full-time agent ever since.

In 2002, Jim spawned the idea for 2PercentCommission.com.

Today, Jim, Sr., is a loving husband and father of three. His interests include social entrepreneurship startups, the study of negotiation, real estate investing, and of course, spending time with friends and family.

In his free time, he can be found working on a non-profit project with his daughter, operating the 59th street community garden, opening a brewery startup with his son, or taking his boat out at the Jersey shore.
