I listened (watched) an interview between Tess Diaz, Executive Producer of domainsherpa dot com and Morgan Linton, co-founded of Bold Metrics. Earlier in the interview Morgan used the real estates metaphor, later Tess succinctly compare domain name investing to classic car auction. Morgan submitted that he prefers Tess's analogy.

Which metaphor do you prefer?
