Business owners BEWARE! I purchased a commercial property that was listed by Justin Riviera of the LUND Company. My intention was to grow my business by moving it into a building that I own rather than rent. I thought that it was standard to tell the realtor what your intentions are. I told him that it was highly confidential and I did not even want my employees to know. Justin told me that his girlfriend owed a salon/spa and wanted talk to my landlord about her renting it. I gave him the contact info thinking that he was doing me a favor.
What he actually did was call all of my competitors. He gave them my confidential info about the move in an effort to collect a commission for renting the space. This is not what I'd expect from a company that specializes in Commercial Real Estate.
