My main source is Inman News, which a subscription is $150 a year. The subscription allows me to receive their very informative "special reports" on trends etc. Through my membership in National Assoc. of Realtors, REBAC, CRS I receive magazines/newsletters as part of my fees which are total about $300 per year.
My membership dues of $540 year in my local MLS provides quarterly reports in depth on our local market sales,changes etc. This is the most statistical out of all of them.
My biggest expense is to my local board of Realtors(RSAR) for $650 per year and that gives me membership in National Assoc. Realtors (NAR), Nevada Assoc. of Realtors (NAR). They provide panels, newsletters, statistics websites etc. All of thos orgainizations have websites where we can do our own research. I spend about $1300 per year for everything.
Additional expenses would be luncheons with speakers and/or continuing education classes which are about $300 per year.
