Get a reputable tile guy to look at the shower. His opinion is worth way more than a home inspector.
But basically I'm right with the first reply. Welcome to home ownership. There's always something to deal with. Usually minor, but sometimes not.
One thing to consider: now the homeowner has a disclosure issue. In my state, and most, if not all others, if you know you have a roof leak, you have to disclose it in the listing documents, and that will make the house a lot harder to sell. Good incentive to make an allowance for it.
When we bought our house the seller had to pay for $10,000 worth of foundation drainage for that exact reason -- they didn't want to pay for it, but they thought we would walk, and then they'd need to disclose that in the listing. :thumbsup:
Assuming your Realtor isn't the listing agent, then you can use them to help feel out the seller regarding stuff like this. Your Realtor, if you've established a buying relationship with them, will get a commission no matter what house you buy, but the listing agent (basically) only gets a commission if the house sells prior to their contract expiring.
