would I earn more money as a real estate (residential) sales agent or as a commercial broker?
Commercial brokers I think earn more, at least they did in the past. But neither job is doing that well in this economy. I kind of think that currently you would do better in the residential sector of the real estate field. I see a LOT of commercial buildings sitting vacant. I live in Seattle and some developer put up a 'glass tower' like two years ago. It's sitting there absolutely vacant (about 40 stories tall). On the same note, developers threw up very many condos around here in downtown Seattle. I can look out my window and see them. Guess what? They are like 95% unoccupied. So-called 'zombie condos'. People are having trouble affording real estate in this recession. (I have a nice apartment across the street from these massive condo buildings. I never see any lights or TVs at night in them when I look out my window - that's why I know that those buildings are for the most part unoccupied). So, five years ago, real estate was kind of a booming business here in the USA, but the bubble burst. It's going to be awhile before it really comes back - I'd estimate ten years, if ever.
