@James Sestito - Thanks for the tips! Let me explain a little bit why I want access to the MLS and this might help answer the question.
I am looking for distressed properties that I can buy direct from the seller. In order to feel comfortable about my MAO, I need to have a solid ARV. In order to do this, I need to run the comps (and not just what you can find on Realtor.com, etc.) and since I won't be using an agent, at least on the buying side, I want to have the ability to run the analysis myself.
I also want to run some ad hoc/routine analyses of historical/recent sales data in my area so that I can get a better sense of the market and recent trends, and possibly develop some insights on future performance. This will allow me to better define/continually redefine my buying strategy. This will likely require extensive data dumps, something that I don not necessarily want to ask of an agent. I can get some sales data online through multiple sources, but it does not have the level of granularity that I desire.
Hopefully this helps clarify.
