LTVP + pass and HDB ownership

[mistletoad]

Do understand that my spouse and my LTVP+ allows us to own only a pre-owned HDB property. That's fine as we've been married for 35 years. So if I survive my wife... so how do I keep my life in Singapore and the HDB flat which is our/my home, with family(22 nieces and nephews). PRs are quite complicated at my age, even though have quality retirement income. So if I survive my sponsor and have to sell my HDB flat… and must have to leave.?. just in case PR unachievable … any other thoughts/suggestions, as spouses are the only sponsors for the LTVP+ pass.

Cheers !
