Your algorithms are inaccurate when dealing with a small eclectic neighborhoods like this. I was offered 500,000. thousand dollars for this ocean front house before it was finished being built in 1986. Try to find an ocean front house that is on private ocean front property , not a co-op, only thing you own there is a share. There are only about 10 ocean front houses here. Nothing else is a comparable. When you say a house is a comparable that is not a comparable you affect the estimate. Since hardly any really comparable houses exist, and those that do rarely come onto the market, your estimates are wrong. A shack in the woods, or an ocean view house is not an ocean front house and therefore not a comparable. Go north to Oregon, or south to Trinidad California and try to buy something like this for less than 1 million. Try to find a ocean front lot that can be built on, even. This is a property worth way over a million dollars, and anything less is not accurate.
This property is off market, which means it's not currently listed for sale or rent on Zillow. This may be different from what's available on other websites or public sources.
