To get precise data on the highest condo rental transactions, you would need to access detailed rental transaction records, which are typically available through real estate agencies or property portals like EdgeProp Singapore. However, based on the available information, it is clear that executive condominiums and newer developments in the North region are popular and likely to have higher rental values due to their amenities and location.
We appreciate you using EdgeProp Buddy. As I'm in Beta mode, I'd recommend seeking expert advice in real estate for such concerns.
