Can someone above 60 years old apply for a Prime 4-room flat

Based on the search results provided, there is no specific age restriction mentioned that would prevent someone above 60 years old from applying for a Prime 4-room HDB flat.

The standard HDB eligibility requirements indicate that applicants must be at least 21 years old (or 35 for singles applying alone). However, the search results do not detail additional age-related restrictions for Prime category flats beyond these baseline requirements.

What you should know about Prime 4-room flats:

Key differences for Prime flats:
- Prime flats have a 10-year Minimum Occupation Period (MOP), compared to the 5-year MOP for Standard flats
- The income ceiling remains $14,000 for families applying for Prime 4-room flats
- Prime flats are part of HDB's new classification framework and target different buyer segments with enhanced design and pricing

Important consideration:
The 10-year MOP for Prime flats means you would need to occupy the flat for 10 years before you can sell or rent it out. Given your age, this is a practical factor to consider when deciding whether a Prime flat suits your needs.

For a definitive answer specific to your situation, I recommend checking directly with HDB or using EdgeProp's eligibility tools, as age-related considerations for older applicants may have nuances not fully detailed in the available information.
