In my state it doesn't.Commercial deals also do not fall under (RESPA) Real Estate Procedures and Settlement Act.
Business brokerage sales in my state does not even require a real estate liscense.Business brokerage is where only the exchange of assetts is being sold.Like a restaurant that does 10k a week in sales but lease the space and does not own the land or building.Many former stockbrokers do business brokerage in my state.
