Seller won't budge

[Mauricio Salom]

I'm working on my first purchase in SD, CA but it seems like sellers in this market are very stubborn. I placed an offer on a SFR listed at $400k. My offer was $390k and i asked for $6k for closing cost. They countered with $399k and $5k back. The house has been on the market for a few months (2 or 3) and the agent I'm working with says the house should appraise near $400k. I'm using a conventional loan with down payment assistance so I was told that my lender couldn't help with any type of closing costs. Do I have any other options other than raising my offer or walking away?
