It appears that the current wholesale minimum for 3-letter .com domains is about $1200. I haven't personally seen a 3-letter .com of any quality level sell for less than $1200 recently, and I'd further say that any that could be found for less than that amount, if still possible, would be a good buy.
This also represents a strong valuation growth...as there were a few 3-letter .coms bought about 2-3 months ago at around $1000, but that price seems to be too low now...and price momentum has continued to grow.
To my thinking...3-letter .coms have been one of the most safe and one of the more profitable domain investments over the years. They have continually increased in value at an impressive pace and I see no reason for that to change. There are only 17,576 of such names, and fewer and fewer are still for sale in the marketplace. As more and more fall into end-user hands (including two I just sold to end-users in the last month), the supply dwindles and demand will continue to force prices higher on both the wholesale and the end-user marketplaces.
Hope this is helpful.
Thanks,
Zesty
