Taking over family owned business

[David Blue]

Hi,

 I am taking over a 20 year old family real estate brokerage business.   I am new to the real estate business but I have had a RE brokers license for some time and never used it.  The business is located in Brooklyn New York and there will be roughly 3 agents working with me  It is mainly a commission based on sales and rentals fIrm  and though it has survived the last 20 years it needs new business model ideas. 

I am interested in responses which  can give me ideas on how to generate new income and use technology to achieve this. What other avenues can I pursue in the Brooklyn New York area besides commissions based on sales and rentals?  What other options are there available to me out there? 

 As I mentioned, I am new to this so any advice would be helpful and I know this is the place to reach out for guidance and advice.
