New Unexplored Niche ..Results?

I have currently stumbled upon a niche that almost appears to be un charted territory.All the perfectly targeted keywords are all available as domains as well.I was sure this was a great sign.

Every single targeted keyword that i can think of is still available as domains.In fact there are several major companies in this niche and they are mostly all national companies..Every domain i can imagine is still available except of course the exact name of the niche..

In reference to the multiple keywords as i mentioned above ,After googling these and writing down the results i find that 50% have around 35,000-50,000 results and the other 50% have much less than that..This is a little confusing to me .As i once learned when i first came to this site that if there is a niche out there not being explored ,well then there is probably a reason..But on the other hand this is a relatively strange niche much more common then you would think but is not talked about much and is unheard of as well..The only time this topic comes up would be in a lawyers office perhaps or even in realtors office perhaps....

Of course you know i cant really mention this niche name as of right now until i have riddled out exactly what i am going to do...
