Question: Making an offer on something found on MLS

[Arthur Fuller II]

I found something on the MLS (redfin actually). The asking price is $285k and I want to offer $190k. How do I make this offer? Do I just call the listing agent and asking if his seller will take $190?

Its been listed for 111 days. The price has been dropped from 318 to 285. I's been empty for years - and most importantly....ITS DIRECTLY ACROSS THE STREET FROM THE PROJECTS
