Here are what look like the good points of City Gate from an investment perspective:
1. Prime / Central Location
• Very centrally located — near Bugis / Marina Bay / CBD area. Good for people who want easy access to work, shopping, food, entertainment. 
• Direct / easy access to Nicoll Highway MRT (Circle Line). That helps with rental attractiveness and resale. 
2. Mixed-use development with retail
• Having the commercial / retail podium means potential for both residential and commercial rental income. The shops/restaurants downstairs are conveniences for residents, but also sources of income/yield. 
• The ground floor / retail units seem to have good tenant mix (non-discretionary goods/services, etc.) which may be more resilient in downturns. 
3. Variety of unit types
• Dual key units, penthouses etc. means multiple appeals: for owner-occupiers, or investors seeking multiple smaller rentals or splitting. Diversity in unit mix helps diversify risk.
4. Amenities & Design
• Facilities are decent (pool, sky terraces etc), plus good views (city & some sea depending on orientation). Those non-tangible features help with desirability.
5. Capital appreciation potential
• Because it’s in a prime district, demand tends to be strong, and scarcity of new prime CCR (Core Central Region) supply helps. Also the connectivity and location near growth & commercial precincts (Kampong Glam, Bugis etc) could mean further upside.
