The Greens possession in March — here's my real truth

Okay, I'll be honest — I thought I did enough due diligence on The Greens. Possession was in March, and already seeing minor seepage near the balcony and some cheap fittings coming loose. This makes me worry about long-term maintenance and resale value. Also, the promised 'state-of-the-art' gym is barely half-equipped. Are amenities just bait? Does good construction always outweigh minor amenity issues for tenants/resale?
