I agree everything examplens have mentioned it really takes time and effort to get approved your application in adsense. So this is really a good offer but i doubt how to make both parties fair and OP should be open for escrow.
These are Adsense Criteria for 2023
you must have control of your site
your site must contain unique and interesting content
your site must have clear navigation
you must avoid driving fake traffic to your site
your content must comply with Google content policies
you must not include copyrighted content in your blog without permissions
you must use a supported language
your site must not contain the abusive experience
you should have technical pages
make sure your site is at least six months old
have some sufficient traffic
number of posts.

Maybe OP will have a taker but both parties should know the risk and how to have a better deal.
