I'm not going to overrepresent my expertise, but both the flooding and egresses are fixes that will eat into profit (10s of grand), but I doubt would turn it into a loss with the numbers I see. Plus they're wiggers so they'll probably have a friend do it for cheap and cut corners.
People have different taste, and just like above people will buy things at a discount all the time. Nick love's his mid-century, which I think is dogshit. I'd still live in one at the right price. The house I live in has a pretty dog shit floorplan, but it checked a ton of other boxes and I got it at a great price, so I'm happy with it. It's usually never prohibitory expensive where you can renovate a house to be more appealing and just factor that into the price you are willing to pay for a house.
I'll try looking into the S3 house more.
