Full CPF for every buyer age today. First to lose it: age 25 buyers in 2035 (9 years away).
When your buyers disappear
CPF may only be used in full where the remaining lease covers the youngest buyer to age 95. Below 20 years of lease, CPF cannot be used at all. Each row is the year that age band loses full CPF funding for this block — and with it, part of your exit market.
