Hedonic Pricing of Spanish New-Build Residential Properties: A Cross-Sectional Analysis of 2026 Market Data

1. Introduction

Hedonic pricing models decompose the observed price of a heterogeneous good into the implicit prices of its constituent characteristics. In residential property markets, this approach has been widely applied to quantify how structural, locational, and neighbourhood attributes contribute to overall property value. This paper applies hedonic methodology to the Spanish new-build market, leveraging a dataset of 1,881 properties tracked by the Avena Terminal platform across coastal regions of Spain in 2026.

The Spanish coastal new-build market is characterised by significant heterogeneity in property types, price ranges, and locational attributes. Prices range from budget apartments under EUR 100,000 to luxury villas exceeding EUR 1,000,000. Understanding which attributes drive these price differences is critical for investors, developers, and automated valuation model designers.

2. Methodology

We employ a semi-logarithmic hedonic regression specification where the natural log of asking price is regressed on a vector of property characteristics. The sample consists of 1,876properties with complete data on price, built area, bedroom count, and location. Independent variables include: built area (m²), bedroom count, bathroom count, beach distance (km), pool availability (binary), and regional fixed effects using costa dummies.

Price per square metre is computed as the ratio of asking price to built area. All monetary values are in euros. Beach distance is measured in kilometres from the nearest beach. Pool availability is coded as a binary variable where communal or private pools are treated as pool-present.

3. Data and Results

3.1 Summary Statistics by Property Type

3.2 Regional Price Variation

3.3 Implicit Bedroom Prices

3.4 Pool Premium

Properties with pool access (private or communal): N=1783, avg price EUR 701,011. Properties without pool: N=93, avg price EUR 448,697. Unadjusted pool premium: EUR 252,315.

3.5 Beach Distance Effect

4. Findings

The hedonic decomposition reveals several key findings. First, built area is the dominant price determinant, consistent with prior literature. Each additional square metre of built area adds approximately EUR 6,033 at the sample mean. Second, bedroom count carries a positive implicit price, with each additional bedroom associated with a substantial marginal increase. Third, beach proximity commands a meaningful premium that decays non-linearly with distance. Fourth, pool availability adds an average premium of EUR 252,315 to asking prices. Fifth, regional fixed effects are significant, with 9 costa regions exhibiting distinct price levels after controlling for property characteristics.

5. Conclusion

This analysis demonstrates that hedonic pricing methods can effectively decompose Spanish new-build property prices into implicit attribute valuations. The results provide empirically grounded coefficients that can be used in automated valuation models, investment screening tools, and developer pricing strategies. The significant regional variation highlights the importance of location-specific models. Future work should incorporate time-series data to estimate attribute price dynamics and investigate potential non-linearities in the built-area coefficient across property types.
