Amenities like security, power backup and reliable water supply tend to affect daily quality of life directly and consistently, making them worth prioritising over more discretionary features.
Lifestyle amenities — clubhouses, swimming pools, landscaped gardens — add genuine value for residents who use them regularly, but their impact varies by household, so it is worth honestly assessing how much you would actually use a given amenity before letting it influence your decision significantly.
Also consider the ongoing maintenance cost associated with extensive amenities, since more amenities generally mean higher monthly charges to sustain them.
