1. What made you buy it?
2. What could someone do with it?
3. Who's you target Market to resell to (shouldn't be speculative domainers unless you are aware of a domainer targeting a certain Market - then of course they become your Market)
4. Domain prices are small, and costs to resell are next to nothing - just your own time - but like any resale purchase you have to know who your buyer is and where to find them
The right finance names or developed sites with traffic are always going to get interest - I'd ask a question already asked which is local exacts on GWT - it will give you an idea as to whether there is an immediate Market for a speculative domainer to target - or is it just brandable and someone's going to have to use some creativity
You might find it better to brand this, develop a site targeting an industry that is highly profitable and then resell. The name would be easy to sell in this type of situation
