Yes, I will buy them from you
You can check out my mini BB portfolio:

4 letter .com's are a weird creature unlike most domains. Most people/businesses don't understand the value in 4 letters .com's. But that doesn't mean they are not worth it, it just means your chances of selling are a lot less. However, 4 letter's have a LIQUID wholesale price any day of the week. 5, 6, & 7 letter .com are NOT liquid like 4 letters are.
4 letters have an expensive 'purchase' price but you are almost guaranteed to get your purchase price or more back from a quick flip. But if you want to sell your 4 letters at retail, you must be willing to be a long term investor who can have your capital tie up for many years. Which in ten years, most 4 letters will be selling for at least 1k IMO
Since 4 letters have a 'category' of their own on BB, these domains get more search love AND its easier to search threw the 4 letters because their isn't very many.
I'm the owner of RAQK and of course RACK would be better, but it would also cost a fortune!! The reason names like RAQK are on BB is because a startup can buy RAQK for 3.5k and grow their business into a multi-million dollar company and THEN go buy RACK with ease.
Im also the owner of OVZU, which for a US based business might be a unique, but for an international company based in another country, OVZU has global appeal. It would be interesting to get stats on BB sales outside the US.
