My simplest answer would be.. Do what you love and the money will follow. We have Realtors in our area that make 100k+ a year with no problem (and for my area the average home is 300k). Which is a great salary in my opinion.. we also have Realtors that make 20k a year due to the fact that do not really work at it. Getting into real estate now or in the height of the market does not make a difference, it is the amount of work you put into it. These days, I switched from doing straight resale, to adding some REO business into the equation. This allows me to gain some extra income and fill my database with some Investors who will continue to buy from me even when the market is back at its peak.
If you want to work in Real Estate you have to do it because you love working with people, either helping them sell or buy a home... there are many easy ways to make 100,000 a year but real estate just happens to be one of the most fun ways!!
