Creative ways to offer to lower the price?

[Isaac Johnson]

Hey BiggerPockets community! 
This is my first post so not sure if I'm in the right spot. Basically, I've only ever bought turn-key single-family homes and I'm trying to level up to multi-family. My area is really booming with growth so I'm trying to grab everything I can. I was approached about a 4-plex in a decent area that's been redone (nothing crazy, new carpet and countertops)
But the rent comps and the price are just terrible ROI.
I guess my question is, what would you do in this situation. I've asked for owner financing and I've submitted an offer and he responded "you're way off" lol. 
Do I just walk away? I need him to come down from 875k to 800k for it to be even close to a good deal. Rents are about 1200/unit
