Ok let me summarise. TS thinks HDB is unfair because 1) they offered you low floor, 2)subject to repricing, 3) your wife being PR won't get as much benefits
1) Low floor - HDB is actually being fair. They can't offer you higher floors since those would have been taken by ppl who got low numbers in the ballot. If they offered to you instead would that be fair to others who were luckier than you and got low low numbers? No point balloting, all of us go complain to MP then can cut que.
2) Repricing - This one I don't know fair or not. If what they offer you is a BTO launched a year ago and prices have increased since then I guess it is justifiable for them to offer a repriced rate. Else it won't be fair to newer BTO applicants where the price already reflect market conditions.
3) Wife not being PR. This one other CSers have responded already. Btw, if you buy the HDB and your wife becomes a citizen later, CPF will refund you the difference in subsidy. So I think it's fair.
