Zara's take · Cornwall
Cornwall is currently a leaning toward buyers.

The latest monthly average sold price is roughly 7.3% lower than 12 months earlier. Monthly averages move with the mix of homes that sold, so treat this as a direction rather than a precise change. Inventory is tight at ~2.7 months of supply.

Practical takeaway

Buyers: you have real negotiating power right now. Sellers: consider pre-listing inspections and competitive pricing to stand out.
