Another possible option: buy the 5 year Singapore Government Security (government bond) that's coming up for auction later this month (January, 2018). The issue code is N518100E. It's AAA-rated, and it'll probably yield about 1.75% (noncompetitive bid), assuming market interest rates stay right about where they are.
They're no extra charge to buy, no extra charge to hold, and your coupons and return principal are guaranteed by the Singapore government. It's a great way to save for a down payment, if that's what you want to do. Just approach DBS/POSB, UOB, or OCBC to buy it. I believe you'll have to place your order by January 26, although January 25 would be safer.
N518100E should be slightly better than this month's Singapore Savings Bond since you already know you're going to hold it for 5 years, and since the coupons are level (and thus more front loaded than a SSB). You can reinvest the coupons, of course -- into SSBs, if you wish, or take a yield gamble on Citi's MaxiSave.
You can also "divide and conquer" if you wish. For example, you could put $15,000 into Citi's MaxiSave (the minimum practical amount in order to avoid a monthly fee) and the rest into the 5 year bond. And that's not a bad way to go, actually, because you'll need slightly more working capital to guy the SGS at initial auction, usually 15% above face value. You'd put up $40,250 (115% of $35,000), get back approximately $5,250 (exactly how much depends on the auction price and coupon that MAS sets, but it should be close to par), take that plus the rest of your remaining cash and put it in MaxiSave. Or the March SSB, if that looks good.
So there you go: N518100E.
