The inspection agreement caps what I can recover at the inspection fee. Is that normal?

You'll see all three of those clauses in most inspector agreements, so nothing you quoted is unusual on its face. The limitation-of-liability paragraph is close to industry standard, and inspectors carry errors and omissions insurance behind it, which is the actual reason the cap exists. Whether a court will enforce a cap that low against a negligence claim varies by state, and some states won't enforce it at all in certain circumstances. That's a question for an attorney licensed where the house is, not something you can settle by reading the paragraph again.

The one I'd actually pay attention to is paragraph 13. The notify-before-you-repair requirement is the clause that trips real people up. Your heat exchanger cracks in November, you're cold, you call an HVAC company, they replace the furnace and haul the old one away, and now there's no evidence and no claim. If you ever think something got missed, call the inspector first, before the repair truck. That habit is worth more to you than the wording of the cap.

On Friday versus shopping the form: take Friday. You'll get materially the same document from the other two, and losing three days of your inspection period costs you more than a better paragraph 9 will ever pay you. What you'd actually be shopping for is the inspector, meaning how long he spends in the house, whether he lets you walk it with him, and whether he walks roofs or shoots them from the ground. Ask those three things by phone in ten minutes.

Also, 495 was never going to cover a furnace. What you're buying is the chance to renegotiate or walk before you own it.
