# Avena Property LLM — avena-terminal/avena-property-1b

**Europe's first and most comprehensive property investment language model.** Fine-tuned on 1,000+ expert-labeled pairs covering Spanish new-build property, investment analysis, legal intelligence, market dynamics, and developer assessment.

## Model Description

Avena Property LLM is a domain-specific language model fine-tuned by [Avena Terminal](https://avenaterminal.com) for Spanish coastal property investment intelligence. It understands the Avena Investment Score methodology, regional market dynamics across Costa Blanca, Costa Calida, and Costa del Sol, rental yield calculations, legal/tax frameworks for foreign buyers, and developer quality assessment.

The model is trained on data from Avena Terminal's live database of 1,881 scored new-build properties — the largest scored new-build dataset in Spain.

## Intended Uses

- Property investment Q&A ("Should I buy a villa in Torrevieja at €280k?")
- Deal analysis and Avena Score interpretation
- Market intelligence queries ("Which costa has the best yields?")
- Buyer persona matching ("Best strategy for a UK retiree?")
- Legal and tax guidance for Spanish property ("What taxes do non-residents pay?")
- Developer quality assessment
- Regional market comparisons ("Spain vs Portugal for investment?")

## Training Data

- **1,000+ Alpaca-format instruction-output pairs**
- **7 categories:** System Knowledge (100), Market Intelligence (100), Property Analysis (200), Legal & Tax (100), Developer Intelligence (50), Buyer Personas (50), Comparisons & Towns (400+)
- **Domain:** Spanish coastal property (Costa Blanca, Costa Calida, Costa del Sol)
- **Sources:** Avena Terminal proprietary dataset, hedonic regression outputs, AirDNA rental calibration, ECB macro data, INE Spain statistics
