How much does that cost? And is that why the check engine light could be on?

I'm looking at an 2000 Impreza wagon with 194k miles. It seems to have either lifter or valve racket, not sure though. It just seems to have a ticking in the engine. The guy is selling it for $800 but I offered him $650 and he's getting back to me on it. Could be a timing belt? I'm not sure when that was changed last.
