Residential Real Estate Agents Selling Businesses

Today a realtor sent me an email regarding a client of his that was interested in one of my listings. I wrote back that if he was a realtor I would be happy to pay him a referal fee if he wanted to pass his clients on to me. If he was a broker I told him to fill out my co-broker agreement and fax it back to me with a sign NDA from his client.

He sent me a slightly nasty email saying that he had no intention of passing the clients to me and if I don't co-operate he would be interested. I responsed with the following: You don't have to be offended, I have a real-estate license but I don't sell peoples homes just because I have a relationship with them. That would be a disservice to them because it's not my area of expertise and selling business is trickier than buying a home. You should rethink your attitude or become a business broker. Thank you!
