There needs to be a mechanism in planning to only allow residential occupation by local residents.

I live in East Wittering and one of the things which has become very apparent over the last few years is the number of properties, including new builds on larger estates, which are being bought as investment properties and especially for holiday lets. This is pushing house prices higher and excluding local people and families from getting on the property ladder.
