Why sell the report to them? Email it to them and get some discussion going back and forth on some of the main points.
You want them aware of the problems in writing.
Then tell them you want the price discounted to cover all the big stuff.
If you can’t come to a fair price, then send them a release letter that gives them permission to make as many copies of the inspection as they like. So they can hand it out to new prospective buyers to disclose the issues that they are now aware of. Send it via registered mail.
