> But I still cannot find any discount property that is discounted because it's next to the ocean Sea levels are expected to rise about a foot in the next 30 years, which will impair some coastal property but not all (much worse on the east coast than the west). It's much worse on a 60-100 year timeframe. If a discount were being applied, you'd expect most of the reduction in value to be 50 years out. The present values of enjoyment over the next 50 years could far exceed those residual values, and so it could be hard to observe any discount that is present. E.g. even if future sea level rise lops 10% off the value, other factors could add more in the short term.
