Zara's take · St. Marys
St. Marys is currently a balanced market.

The latest monthly average sold price is roughly 19.3% 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 ~3.8 months of supply.

Practical takeaway

Buyers: you have time to make a measured decision and negotiate. Sellers: presentation and pricing strategy matter more than timing.
