Hey, I appreciated your deep concerns here.

And I am almost ready to reveal the true price I got for this house because you have given your estimates many many times. And now I know you did that due to a genuine concern. I really apprecaited that. But you also have to do so homework here, to study the local market more, and the partcular community. Instead of insisting this house is worth what you think it should worth, just go online to look at the listing prices of the houses here (I give you the exact location of the community), and then subtract some amount from the listing price to get a ballpark figure, if not exact figure. But if you are really concerned about this particular house we bought, just QQH me, and I can even give you my phone number for you to call, and let you know everything you want to know about the house.
Hey, you may find something that's more than you already know. The bad thing is "some people don't know what they don't know".
