By "more data points" I meant questions like "Do you have a trampoline?". Read my comment again with that understanding. Elaborating on my second criticism - let's say someone has a trampoline but never has guests at their house. The insurance company asks about the first condition, but doesn't ask about the second condition. If the customer lies about having a trampoline, it's likely that they are actually still being subsidized by their neighbors as their overall risk of liability claims is much lower. And I've actually got to wonder if lying about having a trampoline is technically even fraud. Are home insurance companies legally obligated to pay/defend liability claims stemming from things you lied about? If not, then it would seem there is no fraud (unless you also lie for the claim) - the claim can just be denied, and liability coverage isn't relied upon by a mortgage.
