I'm curious if the population generally thinks this is a reasonable situation. I can easily imagine a 25% difference in valuation of two properties in the same area with the same number of bedrooms, the same age, same space, and nominally the same amenities. I can also imagine a 25% difference based on some newly opened restaurants, new bus routes, etc., that will not be reflected in historical data.

There is also an enormous subjective-experience component in how people value residential real estate, and enormous variation in details that really do matter and aren't available in real estate data aggregates (like lighting profile, and how intelligently the interior design exploits that lighting profile).

It's so far from what I'd consider reasonable based on my (obviously limited) experience, and I'm genuinely curious how the locals feel about it.
