Having many listings; from an agents viewpoint, is not what it once was. Marketability is king these days. With the high volume of short-sales and foreclosures- "real" prices are very difficult to secure.
Best not to use the names or firm names, that would just invite anger and animousity.
Also, be aware that real estate professionals here will likely try to become prospect # 3 or 4 for you to choose from, if the condo is a viable marketable property that they would like to list. I'm including myself in that, so be forewarned. :)
I just wrote an article that you may find useful. A lot of the "known" local Realtors usually market for listings and their inventory can be deceiving. It's about seeing which agent will expose your listing the best and give you excellent service at the same time (no easy task).
If that doesn't work out ... I'll definitely keep this thread in mind. :)
