Appraisal tools need to move forward indeed. But I still have little hope they will indeed hit the nail in the head anytime soon. It's much more complicated I'm afraid. You really have to know the niche well, the companies, the people and the inclination of any potential buyers, make a full persona beforehand etc. Give you an example. There is a highly lucrative industrial niche I deal in. I know the companies as I've traveled all across Europe in the last 10 years (dealing in several industrial verticals and this is one of them; each is different). The trick is, nobody in this industry will buy a related domain. They won't touch it with a long pole. They don't buy domains at all. They even won't buy a website that brings leads daily, when an individual lead can bring an 100K or 1M sale. They say to you, use the website and bring us the orders, not leads. It's common in that industry. So whoever buys this kind of domain by growth, enterprise value etc. is at a loss.
