ATTention Mortgage brokers! Do you have to be employed by the same company to get the fha steamline loan, or just be in the same field?

I am looking to buy a home in the Greenville area, And have only been in Real Estate since Oct. 07. I have multiple streams of income from different jobs I currently have other than Real Estate, but i was under the impression I had to be self employed in Real Estate for 2 years before I would qualify for a loan? Is this true or will they take that I have been in Sells Related fields as well for the past 5 years?
