I learned the hard way. I would ask what type of training they offer, what is the cost (your going to need more training) and where is the training located, in office, another town, ect. Where are you going to work,(do you have a desk). What is the monthly cost,desk fee, ect. Commission split, franchise fee, E&O insurance, transaction fee. What is expected of you, who should you go to when you need support. There's a lot more, but one suggestion I would make is talk to the agents of different companies and ask what they think of the Broker/office where they work. How long have they worked there, and how well they are doing as far as sales. Thats where your going to get the straight talk. Also take a tour of the office.
Good luck.
