I think I found a gem on godaddy auctions, which I just bought for $15. It's a 1 y/o domain which doesn't even appear in ahrefs but it's an EMD(almost, it has a very good sufix), the main kw has almost $100 CPC, and, you guessed it folks, high competition. There are a lot long tails with very high CPC also. Not sure how relevant this is, but Estibot appraises it's value at $700. Right now I am really, really excited, and I need a plan to get the most value out of it. I do not want to say here the exact domain name for the next 3 days and I'm not sure it's wise to do so after. So I do not know how to help you help me.
