Negotiation during Due Diligence period (as is purachse)

[Duncan M.]

Can you still negotiate during a due diligence period even if your sales agreement was "as is"?

The scenario is I found that the duct work in the crawlspace of a single family home I have under contract needs to be completely redone. The cost will be somewhere around $4,000. I do not want to back out of the deal, but I would also like for myself and the seller to meet in the middle if possible.

With an "as is" purchase I know no repair requests are allowed. However, Is it within my right to renegotiate some aspect of the orginially agreed upon terms? I'm up for all ideas, even creative ones.

Thank you!
