This might be a strange article coming from a property agent. My job, after all, involves helping people buy and sell homes. But I have learned that the best way to build trust is to tell people the truth, even when the truth is "maybe you should not do this."
Not everyone who qualifies for a condo upgrade should go through with it. The numbers might work on paper, but paper does not pay your bills when things get tight. And in my experience, the people who regret upgrading are not the ones who could not afford it. They are the ones who technically could, but probably should not have.
Here’s a low-down of what I mean.
When banks assess your loan application, they use TDSR to determine the maximum you can borrow. If your total debt obligations stay below 55% of your gross income, you qualify.
But qualifying is not the same as being comfortable.
Think about what 55% TDSR actually means. More than half of your gross income, before CPF deductions, goes to debt payments. After CPF contributions (20% for most employees), you are left with about 80% of your gross as take-home pay. If 55% of your gross is going to debt, that leaves just 25% of your gross income for everything else.
For a household earning $11,000/month:
That is $2,750 for food, transport, utilities, insurance, children's expenses, medical costs, and any hope of saving for the future. For a family, that is barely enough.
This is why I always tell clients: just because the bank says yes does not mean you should say yes.
Most people focus on the purchase price and monthly mortgage. But upgrading to a condo comes with a stack of costs that catch people off guard.
Let me show you what these actually look like for a realistic scenario.
The purchase:
That is nearly $460,000 before you even get the keys.
The ongoing costs people forget:
Condo living adds roughly $370/month in fees and taxes that HDB owners do not pay. Over a year, that is $4,440. Over 10 years, that is $44,400 in additional costs that have nothing to do with your mortgage.
And we have not even talked about renovation. A new condo unit might need $50,000 to $80,000 to fit out. A resale condo in good condition might still need $30,000 to $50,000 to make it yours.
These are not optional extras. They are real money that needs to come from somewhere.
I recently spoke with a client in Pasir Ris who wanted to upgrade from his 5-room HDB to a 3-bedroom unit at a new EC launch. On the surface, it seemed doable.
Their situation:
The maths:
From the HDB sale:
Their CPF OA would be replenished with $220,000, giving them $460,000 total in cash and CPF.
For the EC purchase:
What is left after purchase: $1,650
Let that sink in. After completing the purchase, they would have roughly $1,650 to their name. No renovation budget. No emergency fund. No buffer for anything unexpected.
Their monthly situation:
They would be spending nearly half their gross income on housing alone. And here is the part that made them pause: they would be moving from a 5-room flat (about 110 sqm) to a 3-bedroom EC (about 90 sqm).
Paying more. Getting less space. Zero financial cushion.
When we laid out the numbers together, they realised this was not an upgrade. It was a financial trap dressed up as progress.
Based on my conversations with clients over the years, here are the situations where upgrading often turns out to be a mistake:
1. Your cash reserves would drop below 6 to 12 months of expenses
Life happens. Jobs get restructured. Medical emergencies occur. Children's education costs spike. If your upgrade leaves you with minimal savings, you are one unexpected event away from serious stress.
2. You are relying on both incomes with no margin for error
Dual income households can qualify for larger loans. But if your affordability depends on both incomes staying constant, what happens if one person loses their job, takes a pay cut, or needs to stop working for family reasons?
3. You would be maximising your TDSR
The 55% limit exists because regulators know that going higher is dangerous. But even hitting 50% or above leaves very little room for the rest of life. A more sustainable target is 35% to 40% of gross income toward housing.
4. You cannot comfortably afford the 4% stress test rate
Banks use 4% to assess your loan, but your actual rate today might be 1.8%. What happens when rates rise? If your budget only works at current rates, you are exposed to interest rate risk.
5. You are upgrading for status, not substance
Be honest with yourself. Is this upgrade driven by what your family actually needs? Or by what you see others doing on social media, what colleagues are buying, or some vague sense that you "should" be upgrading by now?
FOMO is not a financial strategy.
6. You are downsizing while paying more
Moving from a larger HDB to a smaller condo just to say you live in a condo is not upgrading. It is paying a premium for a label. Unless the condo offers something your HDB genuinely cannot provide (location, facilities, lifestyle), question whether the trade-off makes sense.
Before you commit to upgrading, answer these questions honestly:
If you answered "no" to more than two of these questions, I would encourage you to pause and reconsider. Not forever, but for now. The right upgrade at the wrong time can set you back years financially.
Let me be clear: I am not saying you should never upgrade. For many families, moving to a condo is the right decision at the right time. The extra space, the facilities, the location, the investment potential, these are all valid reasons.
But upgrading should improve your life, not strain it.
If your current HDB meets your family's needs, if your finances would be stretched thin by upgrading, if you are doing it because you feel like you should rather than because you genuinely want to, then staying put might be the smarter move.
There is no shame in that. In fact, there is wisdom in it.
The property market will still be there in two years, or five years, when your income has grown, your debts have shrunk, and your savings have built up. The best upgrade is one you can afford comfortably, not one that keeps you up at night.
Not sure where you stand? I built a free affordability calculator that shows you the real numbers: what you can borrow, what you will have left after the purchase, and what your monthly commitment would look like.
If you want an honest conversation about whether upgrading makes sense for your situation, I am happy to chat. Even if the answer turns out to be "not yet."
