Should I sell my HDB and buy a much cheaper HDB or even rent ?
Interesting question.
There are a several possible ways to play this:
1. Some people move out, live in (usually more modest) rental housing elsewhere, and rent their entire HDB unit. If the rental yield on the HDB unit is attractive enough (net of costs, including income tax), then that equation might work. They can change their minds and move back, of course, when the tenants’ lease is up.
2. Some people have a HDB unit that’s too big in the circumstances, so they rent out one room to generate some returns.
3. Some people exchange units for something more appropriately sized, often in favor of a longer leasehold (a leasehold “reset”), especially if they have children who might live in the unit in the future. Or trade for a shorter leasehold/differently sized unit that’s still plenty long enough to cover their entire lives.
4. Some people sell the unit outright and live in rental housing elsewhere.
5. Some people use the HDB Lease Buyback Scheme if they qualify.
6. Some people live in another country with more affordable housing.
7. Some people stay put but remodel.
8. A few of the options above are combinable.
Deciding between these options, and the status quo, isn’t necessarily purely a financial exercise.
