About Impact Coaching Systems


Bruce Blumenthal


“What a helpful tool for anyone (including old pros) acquiring commercial real estate. Too many investors find trouble only after they have closed escrow. However, many after closing issues can be avoided with a thorough due diligence review prior to owning. Mr. Hennessey has provided a thorough overview of the items an investor should investigate.”

Doug Frye

-Former President and CEO, Colliers

“Thorough and thoughtful due diligence benefits everyone involved: Investors gain confidence, reduce expenses and avoid mistakes. Brokers save time and trouble and more importantly, can elevate their client service. At the end of the day, a sound due diligence process creates tremendous value for everyone involved.”


Mike Lipsey

-President, THE LIPSEY CO.

“This information will give brokers another skill set and add tremendous value for their clients. Investors are always looking for better ways and smart team members to purchase investments with. This due dilgence system helps you become a more valuable team member.”

“If you are a real estate investor, this course could save you thousands, tens of thousands, if not millions in your transaction…I would not go into a commercial real estate transaction without it.”

“…Brian’s course covers what you need to know from the start to the end of an acquisition… It is truly a high-quality course and one of the only serious ones out there. The content covered is critical for serious real estate investing.”

“If you are buying commercial real estate, you know the importance of doing proper due diligence. If mistakes are made during this process it could not only cost you the current deal but also cost you the trust of your current investors, your track record, not to mention future deals and the time spent correcting these problems. If you want to make sure you know how to complete proper due diligence this course will get you there. This is such a small investment considering the cost of not completing proper due diligence.”

“Brian has provided our company with outstanding ideas on leasing and due diligence of properties.  Both his one on one coaching and courses has helped me watch out for costly road blocks and sift through piles of data to find gem properties.  I would highly recommend his coaching and courses to anyone looking to start purchasing commercial properties.”

“The tools and systems taught in the course is definitely a game changer. I know firsthand because I have made some of the same mistakes mentioned when performing my own Due Diligence. I highly recommend this course to all Real Estate Professionals.”
