The Money, Timing & Safety Framework

Why this exists

Most people get their property advice from agents trying to sell them something. Sometimes that's fine. Often it isn't.

This is a framework I've used with 20+ Singapore families to diagnose what they actually have, what they actually want, and what's actually possible. Not a unit-pick. A way of thinking.

If you read this and decide you want to run your specific numbers with me, great. If you read this and decide you can do it yourself, also great, that means it worked.

The three checks

Every property decision turns on three checks. Most people optimise one and ignore the other two. That's how a $1.5M condo on paper becomes a $200k regret in practice.

Money — can you afford it

The first check, and the one most people half-do before falling in love with a unit. It covers what the bank will actually lend you, what the taxman takes going in, and what the loan costs you every month after.

• TDSR (max 55% of gross income for total debt)
• MSR (max 30% for HDB/EC)
• The mortgage you actually qualify for at MAS-stress rates (4% for private, 3% for HDB)
• ABSD on 2nd property for SC: 20%. PR: 30%. Foreigner: 60%.
• BSD: 1-6% tiered, depending on price.
• SSD: up to 16% if you sell within 4 years (for property bought on or after 4 Jul 2025; earlier purchases keep the old 3 year, up to 12% schedule).
• Restructuring (transferring spouse's share) is often cheaper than ABSD on the next purchase. Sometimes by S$80k+. Most couples never run this math.
• Lowest fixed 2yr rate today: ~1.40%. Walk-in to a bank? Probably ~1.55%.
• Difference: S$40-60/mo per S$500k borrowed. S$5-7k over a 2yr lock.

Timing — is now the right time

Money tells you what you can afford today. Timing asks whether today is actually the right day to spend it.

• Capital gain takes time. SG private property has done ~3-4%/yr long-run.
• Rental yield by district: D1 ~2.8%, D18 ~3.9%. The "cheap" districts often yield more.
• SSD pushes you to a 4+ year horizon minimum (3+ years for property bought before 4 Jul 2025).
• En-bloc: high reward, low probability. Only relevant for ageing freehold.

Safety — what if things change

Money and Timing both assume today's conditions hold. Safety is the stress test for when they don't.

• Can you still service the loan if rates spike 1pp from where they are today?
• Refinance window: 3 months before lock-in expires. Most people miss it because nobody alerts them, and drift onto a stale rate.

How Money, Timing, and Safety interact

This is where most analysis goes wrong. People look at Money, Timing, and Safety one at a time. They miss the interactions.

Example 1: The Money check has two halves that can disagree. You can afford the monthly repayment, TDSR and MSR both clear. But once you add ABSD to the entry cost, the total capital required makes the deal stupid. A pass on affordability is not automatically a pass on Money overall.

Example 2: The tax half of Money is fine, you're SC, it's your first property, no ABSD. But the financing half says you're locking in at 2.4% when the market is 1.4%. You'd save S$10k/yr by rate-shopping. Same Money check, two different verdicts depending on which half you looked at.

Example 3: Timing says rental yield in D9 is 2.8% and D18 is 3.9%. But the Money check says you only qualify for D18 anyway because of MSR. The "I want D9" preference died at the Money check, but you didn't realise until you'd spent 3 weeks viewing D9 units.

Money, Timing, and Safety don't just stack. They constrain each other, and Safety is usually the one hiding quietly under a Money number that looks fine until conditions change.

The diagnostic questions

For your specific situation, run yourself through these:

1. What's your gross household income? Existing debts?
2. What's your current property, value, outstanding loan, CPF used, accrued interest?
3. Citizenship of buyer(s)?
4. How many property transactions across both spouses, lifetime?
5. Time horizon for next move: 0-12 months, 1-3 years, or 3+?
6. Cash on hand for the next move?
7. What problem are you actually solving, more space, better yield, ABSD optimisation, exit?

If you can't answer #5 or #7 specifically, that's where to start. Not at "should I buy this unit."

What this framework misses

Honesty matters in lead-magnet PDFs.

This framework doesn't capture:

• Lifestyle, sometimes the right answer is "I want to live near my parents." The framework says nothing about that.
• Risk tolerance, two people with identical numbers can want very different exposures. That's fine.
• Family complexity, divorce, remarriage, blended families, inheritance. Each warps the picture in non-generic ways.
• Estate planning, especially relevant for landed + GCB. Different specialists.

If your situation has any of these, get a 1:1 conversation with someone who can hold all three checks + your real life simultaneously. (That's me, but it doesn't have to be.)
