For studying to get your license, you will need to attend a real estate school (not the university or NWACC--junior college) which will prepare you to take your licensing exam for the state of Arkansas. There are a number of good ones, and some offer the majority of the course on line (except, I think, the law part, which you may have to take in person). Then you will need to take the exam to actually get your license. A couple good ones for the NW Arkansas area are AIRE and the Real Estate Education Center. I have taken classes at both of these--the RE Education Center to get my license and AIRE for continuing education. Their websites are: http://www.aire.us for AIRE and http://teachingrealestate.com for the RE Education Center. There are others listed at the Arkansas Realtors Association at: http://www.arec.arkansas.gov/licensing/Pages/EducationProviders.aspx
I would then suggest you interview with a number of different companies to see what they offer. In NW Arkansas there are some local companies who are very well-thought-of, as well as offices of national franchises. The courses you will take to get your license don't necessarily prepare you for the actuality of practicing real estate. I personally work for Keller Williams Realty in Fayetteville, an independently owned office of a franchise company. There are representative companies here of other Francises including Remax (better for more advanced, experienced agents), Coldwell Banker, Weichert and others.
I started with a local company and moved to Keller Williams in 1994 when the office in Fayetteville first opened. I will be happy to talk with you about working in real estate and in NW Arkansas in particular. Just call me on my cell at 479-966-0435. KW provides wonderful training and resources to grow your business.
