Hmm, what i meant is that the FD rates really cannot be used as benchmark compared to rental yields. FD depends on lump sum payment. Assume 1. you have 100k now 2. rental yield and FD at 3%. If you choose to put in FD, you get 3k after one year, 6.1k 2nd and so on, maybe at 5th year you've got >15% over your capital, however, that's only a 16k+ profit. If you put in property, you're leveraging money, your capital vs yield scales differently along the years (i.e. lose money till breakeven, then accelerated earnings over the years, then stabilise, then decelerated earnings as the property turns older<more for leasehold>).
You can try download a amortisation chart/spreadsheet and compare yourselves.
Btw, Impiana 2-rm is 106-112 sqm, 3-rm is 130-134 sqm. Not one tier above HDB's size, ish two tiers
