What is a Joint Home Loan in Singapore?
A joint home loan, also called a joint mortgage Singapore or couples home loan, involves two or more applicants sharing responsibility for repaying a property loan. This is common for married couples buying BTO HDB flats or families supporting first-time buyers.
In Singapore's regulated market, governed by MAS and HDB, joint applications increase total borrowing capacity under TDSR (Total Debt Servicing Ratio) limits of 55% of gross monthly income. For example, a couple earning S$8,000 combined can borrow up to S$1.2 million more than singles, based on current 3M SORA rates around 3%.
Homejourney verifies all data to build trust, helping you avoid pitfalls like mismatched incomes that lead to rejections. Unlike solo loans, joint setups require all borrowers on the property title, per MAS rules[3].
Real example: A young couple in Punggol applying for a 4-room BTO uses joint incomes to qualify for a S$500,000 bank loan, paying S$2,500 monthly.
Joint Home Loan Eligibility Requirements
Eligibility hinges on citizenship, age, income, and family ties. At least one applicant must be a Singapore Citizen (SC); others can be SC or Permanent Residents (PR).
- Age: Minimum 21 years; maximum tenure ensures no borrower exceeds 65 at maturity (e.g., 30 years for HDB bank loans).
- Income: Minimums vary by bank—DBS requires S$24,000 p.a. for main applicant, S$12,000 for joints like spouses[1]. Maybank needs S$48,000 combined, with main at S$30,000[2].
- Property Ownership: All co-borrowers must be co-owners; no dual HDB ownership allowed[3].
For HDB loans, apply via HLE Letter online with Singpass, factoring family nucleus[4]. Fiancé/fiancée scheme allows pre-marriage buys if married by key collection[5].
Income-Weighted Average Age (IWAA) Explained
IWAA lowers effective age for older borrowers: IWAA = (Age1 x Income1 + Age2 x Income2) / Total Income. A 50-year-old (S$5,000/month) with a 30-year-old child (S$7,000/month) has IWAA of 38, enabling 27-year tenure[3].
Who Can Be a Co-Borrower? Rules and Restrictions
Co-borrowers must be immediate family: spouse, parents, siblings, children, or fiancé/e. Friends or distant relatives qualify only for private properties, not HDB.
| Relationship | HDB Eligible? | Private Property? | Bank Example |
|---|---|---|---|
| Spouse | Yes | Yes | OCBC, UOB |
| Parent/Child | Yes | Yes | DBS (S$12k min)[1] |
| Sibling | Yes | Yes | Maybank[2] |
| Fiancé/e | Yes (HDB scheme)[5] | Yes | HSBC |
| Friend | No | Case-by-case | Standard Chartered |
As co-owner, you're liable for the full debt. Selling your share triggers refinancing[3]. Homejourney's mortgage calculator simulates joint scenarios safely.
HDB Loans vs Bank Joint Mortgages
HDB loans cap at 75-90% LTV, 2.6% fixed rates (2026), no TDSR but MSR (30% income). Banks offer up to 75% LTV, SORA-pegged rates (3-3.5%), full TDSR application.
- HDB Pros: Lower rates, CPF-friendly for public housing.
- Bank Pros: Flexible tenures, cashback; compare on Homejourney bank rates.
For joint couples, banks suit upgraders; HDB for BTO. Singles post-2024 can joint with family for 2-room flexi[6].
TDSR and MSR: How Joint Incomes Affect Borrowing
TDSR limits total debt (loans, cards) to 55% gross income; MSR to 30% for HDB. Joint incomes aggregate: S$10,000 monthly allows S$5,500 TDSR servicing.
Example: Couple (S$6,000 + S$4,000) at 3.5% SORA, 25-year tenure: Max loan S$1.1M (monthly S$5,500).
Calculating Your Joint Borrowing Power
Use formula: Max Loan = (TDSR Income x 0.55 - Other Debts) / Monthly Repayment Factor. Factor for 3% rate/25 years ≈ 0.0048.
Table of Joint Examples (3M SORA 3.2%, 2026):
| Joint Incomes (Monthly) | Max HDB Loan (MSR 30%) | Max Bank Loan (TDSR 55%) |
|---|---|---|
| S$8,000 | S$650,000 | S$1,000,000 |
| S$12,000 | S$900,000 | S$1.6M |
| S$16,000 (Family) | S$1.2M | S$2.1M |

SORA Rates and Joint Loan Costs
SORA (Singapore Overnight Rate Average) is the key benchmark for floating joint mortgages Singapore. 3M SORA averages 3.1% (Feb 2026), plus 0.5-1% bank margin.
The chart below shows recent interest rate trends in Singapore:
Rates stabilized post-2025 hikes; lock fixed for 2-3 years if risk-averse. Joint loans amplify savings: S$1M at 3.2% saves S$20,000/year vs 4% solo.

Risks and Responsibilities of Joint Borrowers
All are jointly liable; default by one affects credit. Divorce requires decoupling/refinancing. Tip: Discuss exit strategies upfront.
Insider tip: For HDB in mature estates like Toa Payoh, banks scrutinize incomes stricter due to higher prices (S$1.2M avg).
Decoupling and Joint Mortgages
Decoupling lets one spouse retain ownership by paying cash. See Homejourney's guides: Decoupling Property Mortgage: Homejourney Application Benefits , Decoupling Property Mortgage Implications: Bank Rate Guide | Homejourney . Improves approval via bank rates.
