Property Daylight Checklist for Buyers

How to use this checklist

Run the same checks for each property, then compare results side by side. Consistency is more important than perfect precision.

Checklist

• Measure direct sunlight duration in living room and main bedroom.
• Check winter shadow impact from neighboring structures.
• Verify orientation and obstruction of major windows.
• Review morning vs afternoon light quality for your routine.
• Evaluate glare and summer overheating risk.
• Compare sunlight quality against asking price and alternatives.

Interpretation guide

• Strong: key living areas receive stable direct sunlight in at least one preferred daytime window.
• Moderate: sunlight is acceptable but limited in winter or blocked for long periods.
• Weak: key rooms remain shadowed for most of the day in target seasons.

Next step

Test top properties with the same date range and scoring logic in the analyzer.
