Advice for a first time buyer

Hi, I want to put in a bid for a condo but am not sure how far below the asking price I should put the bid in for. The asking is $460K and I was thinking about putting my first bid in at $430,000. Or, I was thinking about paying pretty close to the listing price but then asking the seller to pay all closing costs. I don't know which would be more enticing to the seller, to sell the place at a lower price(let's say we agreed at $445K,) or to show that he/she was able to get the full asking price while financing the closing costs.(I think it's the latter, no?) How much leverage do I have in this market?? Any/all advice is appreciated! Thanks in advance.
