Dire is a solid English-language word. If you check the weekly DNjournal lists of sales you'll see similarly good dictionary words commonly going for $4K - 10K range. In this case I think 5K is a sober reseller price and a lowball end user price.
It's a vague word as far as usage goes, however. You have to get inventive to figure out what it can be used for, there's no apparent and clear use jumping out. This can be seen as an asset - a versatile word with many uses - or as a detriment - a vague word with no clear uses.
If you're receiving constant offers below and up to $5K I think it's mostly domainers trying to lowball you. If you need the cash, 5K isn't an insult, it's a good reseller price. If you can afford to sit it out, and you learn how to approach and negotiate with end users, I think you can get into the low xx,xxx for it, maybe $10K - 20K. However since the name has quite nebulous meanings as far as website development or business application... I think any price approaching or over 10K is extremely optimistic, and any price over 20K stratospherically optimistic and only if you have extremely motivated buyer/s.
If I owned it I'd stick a 15K price on it, but accept 7 or 8K probably, if I wanted cash now.
