my first offer on a property

[Harry D Johnson]

Hello BP need some help. I just made my first offer  on a property it didn't  go like I really was expecting,but it help me get over the hurdle of making  a offer so I'm good with that. Ok so my question is what should I do now with that offer? Should I wait him out until he comes down some more or go closer to his asking price  (houses in this market can sit up to a year or so before selling). Based on the info below what should my next step be.

ARV: 210

Asking:155k

Offered: 90k

He told me to go to hell,but he'll take 150k (Lol I think there's still hope)

The property is a 5bed/3bath move in ready house beautiful. 2,818 living space. 

My exit strategy would be brrr, lease option,wholesale.

Thanks in advance for your time and input.
