Hidden damage to the house that wasn’t found in an inspection and not disclosed by the seller. Low level water or termite damage that can’t be seen because a layer of wall was built in front of it.

Just as an example.

How often do those issues come up and what is the typical recovery? I’d guess under 1% and maybe $25K, implying a value of $250. The commission on my house was over 200 times that figure, making for incredibly overpriced insurance if that’s the primary value the fee brings.

I guess it depends on the cost of your house. Everything is relative.

You can always negotiate a flat rate with a realtor too.
