The Income Trap in Property Buying
When most Singaporeans think about what property they can afford, they think about their income. These are important questions, but they miss the bigger picture. Your income determines your cash flow. Your net worth determines your financial health. And it is your financial health that should drive your property decisions.
Over 15 years of advising clients, I have seen high-income earners with dangerously stretched finances because too much wealth sits in property. I have also seen moderate-income clients with robust positions because they sized purchases relative to total net worth.
Understanding Your Net Worth
The Calculation
Net worth is total assets minus total liabilities. Your assets include market value of all properties, CPF balances, cash deposits, investment portfolios, and insurance surrender values. Liabilities include all outstanding mortgages, car loans, credit card debt, and personal loans.
The Property Allocation Ratio
Once you know your net worth, calculate your property allocation ratio — total property value divided by total net worth. If you own a condo worth $1.5 million and your total net worth is $2 million, your property allocation is 75 percent. This ratio tells you how concentrated your wealth is in a single, illiquid asset class.
- Calculate net worth honestly: all assets minus all liabilities
- Property allocation ratio: total property value divided by net worth
- Include CPF, investments, and cash in your total asset calculation
- Include all debts in your liability calculation
- Review and update every six to twelve months
What Your Property Allocation Should Be
The Guidelines
Financial planners generally recommend property should comprise no more than 40 to 50 percent of net worth for your primary residence. Including investment property, total property allocation should stay below 60 percent. In your twenties and thirties, a higher allocation is acceptable. By your fifties, above 60 percent signals potential vulnerability.
Why Over-Concentration Is Dangerous
Property is illiquid — you cannot sell 10 percent of your condo for an emergency. Over-concentration also means under-investment in other asset classes providing liquidity and diversification. I have seen clients unable to seize opportunities because all capital was trapped in property, and others forced to sell at the worst time because they had no liquid reserves.
“The question is not whether you can afford the monthly payment. The question is whether this purchase puts your overall financial health at risk.”
Net Worth Milestones for Property Decisions
First Property Purchase
Your net worth should comfortably support the down payment while retaining at least six months of expenses in liquid reserves. If the down payment depletes your savings entirely, you are buying too early or too expensively.
Upgrade Decision
The new property’s value should not exceed 5 times household income or 60 percent of net worth, whichever gives the lower purchase price.
Investment Property Decision
After the investment property purchase, total property allocation should remain below 60 percent of net worth with 12 months of expenses in liquid reserves.
- First property: net worth supports down payment plus six months reserves
- Upgrade: property value under 5x income or 60 percent of net worth
- Investment property: total property allocation stays below 60 percent
- Always maintain 12 months liquid reserves after any property transaction
- Review allocation annually and rebalance if property exceeds targets
How to Reduce an Over-Concentrated Property Position
Strategy 1: Accelerate Non-Property Savings
Increase monthly investment contributions to equities, REITs, and bonds. Over time, growth in these assets naturally reduces your property allocation percentage without selling any property.
Strategy 2: Right-Size Your Property
If your property is significantly larger or more expensive than needs require, right-sizing can free up capital for diversification. The unlocked equity redirected into balanced investments reduces concentration while maintaining or improving net worth.
Strategy 3: Monetise Without Selling
With significant equity, you can potentially take a home equity loan and invest the proceeds in diversified assets. This involves taking on debt and is only appropriate for financially sophisticated investors.
The Age Factor
Your optimal property allocation changes with age. In your thirties, even 70 percent in property is manageable with decades of compounding ahead. In your fifties, the urgency increases with less time to recover from downturns and retirement approaching.
A useful framework: subtract your age from 80 and use the result as maximum property allocation percentage. At 30, maximum 50 percent. At 50, it drops to 30 percent. This is aggressive by Singapore standards but promotes genuine financial security.
Frequently Asked Questions
Q: Should I include CPF in my net worth calculation?
A: Yes, CPF is a real asset. However, because of withdrawal restrictions, your liquid net worth excluding CPF and property is equally important. High net worth on paper but low liquid net worth means limited financial flexibility.
Q: My property has appreciated significantly. Should I sell to rebalance?
A: If it is your home and you are happy living there, selling involves substantial transaction costs. Focus on growing non-property assets instead. However, if it is an investment you can exit without lifestyle disruption, selling to rebalance can be smart.
Q: What if my net worth is mostly CPF and property?
A: This is common for Singaporeans and carries real risk. If almost all wealth is in CPF and property, you have very limited financial flexibility. Prioritise building liquid savings and investments.
Q: How does debt affect my property allocation calculation?
A: Debt reduces net worth, which increases your property allocation ratio. A condo worth $1.5 million with a $500,000 mortgage has net value of $1 million, but the ratio calculation shows higher concentration than the gross numbers suggest.
Q: Is it possible to have too little allocated to property?
A: In Singapore’s context, owning your primary residence is generally advisable. Having zero property allocation means paying rent with no equity build-up. A primary residence at 30 to 40 percent of net worth is typically optimal.
