@Chambers M Leandra Honestly? Get the sewer line scoped. It's usually a couple hundred bucks for a camera run from the house to the street, and most standard inspections don't include it.
It's the sneaky one. Cracked pipe, roots, or a belly holding water can sit there unnoticed until the backups start, and then you're staring at a five-figure repair. If the house is older and has clay or cast iron, I'd call it a must.
Do it during your inspection window and ask to see the footage, not just hear "looks fine." If it finds something, you can ask for a credit, have the seller fix it, or walk away before it's your problem.
Plenty of other stuff matters too, but this is the cheapest thing to check and the most expensive to miss. That's just what I'd do though, and your inspector or a local pro will know your market better than I do.
