Getting to the big 60 in about 7 months, I believe there will be major changes in the next 5 years.
For one, I've noticed many more mom and pop or single broker stores opening the last few years. Probably because of the single license requirement in our state.
Good RE teams will be much more effective and productive than a company with individual agents. As an example. Our daughter got her brokers license last summer, she joined a high powered 9 agent/staff team which closes about 40 transactions a month. (talking about rebates to buyers/sellers, the top client got a brand new BMW for x-mas as a present)
Commissions will swing with the economic and supply and demand home market, the individual success of some discounters will determine
what everyone else can charge successfully in their market.
As to myself, I do work other RE on the side, buying right of ways (ROW) for city, county and state for a major Engineering Co. I guess I never lost my engineering roots. (and my clients/customers don't have a choice but to sell)
