This is tough to answer as it depends on several considerations.
The intent of EC is good. However, one has to ask whether it is still worthwhile to buy new ECs given the relatively high EC price and, more significantly, the price differential between new ECs and new private condos have narrowed over the years?
My heart goes to those who bought ECs but eventually have to surrender them for various reasons, one of which is unable to form a family nucleus in the next 3 years + 5 years of MOP. It was recently reported that the number of divorces and annulments in Singapore last year was more than 7,000.
So, you have to seriously ask how strong and committed is your marriage to each other.
Another group is those who could not afford the subsequent loan payments eg due to retrenchments, sudden illness. This affects both first-timers and second-timers.
For second-timers, the concern is what if HDB resale prices fall further in the next 2 - 3 years and they could not meet the loan obligations. As shared in my earlier post, a 5-room Sengkang HDB flat has fallen from $530,000 in 2013 to $450,000 now.
You can check the number of returned ECs (and private condos) at squarefoot.com.sg. For these returned units, the buyers have to pay termination fees.
Yes, there are some savings from buying new ECs. But there are restrictions and risks too eg you can't buy another private condo in the next 8 years, the risk of returning the EC unit and the termination fees.
Should property prices come down in the next 8 years, would you miss the boat in that you can't buy a private condo due to the EC restrictions.
So, you have to carefully consider not just the savings but also the potential risks and restrictions.
Is the savings/ risk ratio appropriate in your case?
Is it worthwhile?
