100% this. Ive bought a few domains for companies. In my though limited experience they will be offering 10-50% of what they will pay. Once I bought a small mainly information site/blog a few years back for a bank. We wanted the domain and existing traffic as a better starting point as they ranked well in the space we were interested in. The original offer was 20% of where we were willing to go. The guy didn't even counter offer. Always counter offer.
