I don't think there's a one-size fits all here. It really will depend on the seller and the business they've built, and why they're selling.

If you're a self-funded searcher, I think you need to lean in on your experience and why you're a good fit to continue and grow their business. I almost always freely share my ideas for growth, typically using my skillset I bring to the table. I get a lot of "That's exactly what I would do if I was your age", so I would say it's received positively.

That being said, especially as a younger buyer, you have to demonstrate your surety of close to the broker and seller because if you cant do that then even if they like you and your offer, they're going to go with the "sure thing" even if it's got worse terms.
