No, you cannot buy a balance flat (Sale of Balance Flat or SBF) from HDB while owning and staying in a 2-bedroom private condominium.
HDB eligibility rules for SBF flats, which mirror those for Build-To-Order (BTO) flats, require that applicants must not own any private property or have sold one within the last 30 months. Your current ownership of a private condominium disqualifies you, regardless of flat type, family status, or income.
To become eligible, you would need to sell your private property and wait out the 30-month period from the date of sale completion. First obtain an HDB Flat Eligibility (HFE) letter via the HDB Flat Portal to confirm your status before applying for any SBF exercise.
SBF applications prioritise first-timer families and seniors, with second-timers deprioritised, but the private property restriction applies universally. Check EdgeProp Singapore for upcoming SBF listings and eligibility updates once qualified.
