## When to prefer this

Choose this endpoint when you need a quick, postcode-level rental yield estimate for UK buy-to-let investment analysis. It is ideal when you have a specific property value to evaluate or want a market-average-based yield without needing full comparable listings data. It pairs well with sibling endpoints on the same host for flood risk, council tax bands, EPC ratings, and crime statistics for holistic property due diligence.

## Known failure modes

- Invalid or unrecognised UK postcode returns an error response
- Postcode exists but has insufficient sold price data for a yield estimate
- Property value of zero or negative triggers a validation error
- Service unavailable or rate-limited due to upstream data source issues
