Short answer：A few transactions cannot establish a shrinking sea-view premium. Control estate, date, area, floor and condition before attributing a difference to outlook.
Define the view
Full, partial, distant and obstructed views differ. Inspect from inside the flat and check formal surrounding plans without assuming permanence.
Make the comparison reproducible
Keep samples, exclusions and methods and separate asking prices from sales. Insufficient matched evidence should lead to uncertainty, not an invented discount. Personal enjoyment is not necessarily recoverable resale value.
Before deciding
- Inspect at different times and weather
- Check proposal versus implementation status
- Compare similar layouts and dates
