These two jobs are similar. If you do well, you can make a lot of money. If you don't do well, you won't make money. Besides, there seems to be some connection between these two jobs. If the real estate is booming and everyone invests in buying a house, more and more people will get loans. If the real estate is depressed, loans will be affected. If you have a strong working ability, you might as well do loan work, because there are many people who need loans for investment now, and the house is a little saturated, so it's no good.
