In Aller, the types of properties most affected by price changes are primarily residential units, particularly single-family homes and older apartment buildings. The market is sensitive to fluctuations in demand due to local economic factors and migration patterns, with properties near amenities like schools and healthcare facilities experiencing more significant price shifts. For instance, newly renovated homes in areas like Cabañaquinta generally see a boost in market value, while older, unrenovated properties may languish as buyers gravitate towards more modern options. Additionally, seasonal variations can affect vacation rentals, notably in regions like the outskirts of the Picos de Europa, where price changes correlate with tourist influx during peak seasons. Industrial properties also experience price fluctuations, influenced by the region's economic activity and changes in local employment rates.
