Ask your inspector which findings are serious, then ask the seller for one specific thing.
Almost every building report finds something. The condition works on an objective assessment: a reasonable buyer would also be concerned, not just you. The mistake most buyers make is asking for a discount on everything and losing credibility for the one item that matters.
Your inspector can tell you which findings are serious. Once you know what matters, we go to the vendor's lawyer with a specific request: a repair before settlement with a holdback, or a price reduction with a number attached.
