I have noticed that several people have mentioned real estate as a possible career move if they leave aviaiton. As you all know, becoming a real estate agent today is difficult. One option if you are really into real estate is to look into property and asset management. The job can be a real pain sometimes, but as a career it may be worth looking into if you want something stable. The link below will give you some insight as to the career outlook. Feel free to PM me with questions.
