Pros
If you are an "up and coming" sales type, you can make good money doing something that most of the world thinks is pretty easy - selling title insurance. Most everyone just assumes that he will get it as part of his real estate transaction, so you don't really have to sell. What you do have to do is build relationships with the real estate agents that are selling the houses, and they will refer their clients to you. In fact, they will even fill in the form for the client, because the client doesn't know who to pick. The escrow side is harder, as you actually have to know something to be able to do escrow (I don't think most sales reps even know what they are selling!) and you have to get licensed.
Cons
You are completely at the whim of the company when it comes time to look at laying off people. Every economic or housing downturn, the company will lay people off. Most of the time, the company will lay off the most experienced people rather than the newbies -- and get this, then they will hire temporary workers who know nothing about title insurance or a title plant or research, and put them to doing the work that the laid off workers did. It seems really silly to lay people off who know what they are doing, and then a scant 6 months later hire temps who know nothing.
