How to improve your home loan approval chances in South Africa
The applications banks approve share four traits: a credit score of 610 or more (ooba’s reported bank floor), an instalment under 30% of gross income, a deposit of 10–20% where you can manage it, and a complete document set. bond.co.za’s free pre-qualification estimate shows where you stand before you apply.

What improves your home loan approval chances the most?
Five levers, in the order banks weigh them — and none of them works alone.
A home loan application is scored on your ability to repay and your track record of repaying. The National Credit Act requires every bank to run an affordability assessment, so approval comes down to how the five levers below combine — a strong score can carry a thin deposit, and a big deposit can offset a thinner score, but the weakest lever is usually the one that decides it.
- Credit record: a clean TransUnion record with a score above the floors industry sources report (about 610 for most banks, 670+ for a strong profile).
- Affordability: an instalment that fits the banks' 30%-of-gross-income rule of thumb, with room for rates to move.
- Deposit: 10–20% where possible — a lower loan-to-value ratio means less risk for the bank.
- Documents: the exact payslips, bank statements and proofs each bank asks for, current and consistent.
- Timing: applying while employed in a stable position, with a pre-approval certificate and no recent new-credit activity.
This guide covers the levers in depth. The home loan application tips guide covers the mistakes that sink otherwise sound applications — the two together cover the whole application.
How does your credit score affect home loan approval?
It is the first screen the bank applies — and the floor figures come from industry sources, not the banks themselves.
No South African bank publishes a minimum credit score, but the originators and lenders who see applications daily do state floors. On TransUnion’s 0–999 scale, the figures below are each publisher’s own statement — treat them as ranges that shift with market conditions, never as criteria any bank has committed to.
| Score | What the source claims it means | Source |
|---|---|---|
| 600+ | A score of 600-plus is needed to qualify for a bond | ooba Home Loans — Credit rehabilitation and buying a home |
| 610+ | Most banks look for a minimum score of 610 for a home loan | ooba Home Loans — How to improve your credit score |
| 630+ | The minimum for a home loan is around 630; 600+ gives a fair chance | MortgageMarket — What is the minimum credit score for a home loan in South Africa? |
| 670+ | 670+ significantly improves approval chances and the rate offered | ooba Home Loans — How to improve your credit score |
| 700+ | A score of 700 can be a good one to aim for | SA Home Loans — What is considered a good credit score to apply for a home loan? |
Why the score matters beyond approval: weaker records attract higher margins over prime — within an illustrative major-bank band of prime − 1% to prime + 2% — while approved borrowers average 0.67% below prime across ooba-registered bonds. The score is often the difference between the top and bottom of that band. For the bands themselves and how to read your report, see the credit score for a home loan guide.
What can you afford in the bank's eyes?
The NCA forces an affordability assessment — and the working rule is 30% of gross monthly income.
Under section 81 of the National Credit Act, the bank must assess whether you can genuinely afford the loan. The industry rule of thumb that falls out of that: your monthly instalment should not exceed 30% of your gross monthly income, assessed over a 20-year term by default. At today’s prime of 10.75%, a R 1 500 000 bond over 20 years costs about R 15 228 a month — so the gross household income the rule implies is roughly R 50 761.
| Bond amount | Monthly instalment at prime | Gross income the 30% rule implies |
|---|---|---|
| R 1 500 000 | R 15 228 | R 50 761 |
Two levers move this in your favour: a bigger deposit (a smaller bond means a smaller instalment against the same income) and a lower rate (every 0.67% below prime is real money each month). Run your own numbers in the affordability calculator before you apply — knowing your ceiling is the strongest negotiating position there is.
Does a bigger deposit improve your approval chances?
Often, yes — not because a deposit is required, but because of what it does to the risk the bank carries.
South African banks do grant 100% bonds — there is no legal minimum deposit. But the deposit is still one of the strongest approval levers you control: every rand down lowers the loan-to-value ratio, reduces the instalment against the 30% affordability test, and signals that you can save. On a R 1 500 000 purchase, a 10% deposit removes R 150 000 from the bond — and the interest that rides on it for 20 years.
What each deposit size typically signals, and what a 100% bond really costs in cash upfront (transfer duty, attorney and Deeds Office fees apply either way), is laid out in the home loan deposit guide. If your deposit was funded by a family member or you are pooling income with a partner, both change the documents the bank needs — see the documents checklist.
What documents make an application strong?
Approvals are lost on paperwork more often than buyers expect — incomplete or inconsistent documents stall applications for weeks.
The bank verifies what you claimed in the application: income, employment, debts and expenses. A strong application has every document current, consistent with your application form, and provided the first time — payslips not older than three months, bank statements covering the period the bank asks for, and proof of any extra income you declared. Self-employed buyers need more, and commission earners differently again; the segment-by-segment documents checklist lists each case in full.
Consistency is the part buyers miss: if your bank statements show a debit order for credit your application did not declare, the assessor sees an affordability question mark. Gather your documents, then reconcile them against the form — in that order.
Should you get pre-approved before you apply?
It does not guarantee approval — but it finds the problems while you can still fix them.
A pre-approval check runs the same credit and affordability questions the bank will run, before an offer is on the table. If something fails — a score below the floors in the table above, an affordability gap, an undeclared debt — you learn it while there is still time to fix it, rather than after a seller has accepted your offer. Certificates from the originators typically last 90 days.
The timing matters as much as the check: apply for pre-approval once your credit record is clean and your documents are ready, then house-hunt inside the certificate’s window. The when to apply for pre-approval guide walks the timing through.
Why do home loan applications get declined?
The two reasons that dominate the decline data — and why they are both fixable before you apply.
Across ooba’s reported home-loan applications, 8.4% were declined for poor credit records and 7.7% for affordability, as of 2026-07 — together the two reasons account for roughly one in six declines, ahead of every other cause. Both are visible before you apply: the first on your credit report, the second on your payslip.
Context for timing: TransUnion’s Q2 2026 data recorded new home-loan originations down 10.5% year-on-year, with mortgage activity concentrating among prime and above-prime borrowers. That is a market trend, not a change in bank approval policy — but it underlines the same conclusion: the stronger and cleaner your profile, the better your odds in any market. If you have already been declined, the home loan declined guide maps the fix for each decline reason.

What should you be careful of as you improve your application?
This page states what is publicly reported. Each bank's credit policy is the final word on your application.
The credit-score thresholds in the table above are publisher claims (ooba, MortgageMarket, SA Home Loans), not bank criteria — South African banks do not publish minimum scores, and each applies its own policy to the full application.
The 30%-of-gross-income instalment rule is the industry rule of thumb under the NCA affordability assessment, not a legal cap: banks may accept or decline outside it based on the full profile.
Pre-approval is an indication based on the information you supply — it expires (typically after 90 days), is conditional on the property valuation, and is not a guarantee of a final grant.

Straight answers about improving your approval chances
What credit score do I need to buy a house in South Africa?
No bank publishes a minimum score. Industry sources do: ooba states that most banks look for about 610, and that 670-plus significantly improves both approval chances and the rate offered — on TransUnion’s 0–999 scale. These are publisher views, not bank criteria, and each bank applies its own credit policy to the full application.
How can I improve my credit score before applying for a bond?
Pay every account on time, pay down revolving debt such as credit cards, avoid new credit applications in the months before you apply, and check your credit report for errors and dispute them. Improvements take a few months to register, so start well before you plan to apply.
How much deposit do I need to get a home loan approved?
There is no legal minimum — banks grant 100% bonds to qualifying buyers. But a deposit of 10–20% lowers the loan-to-value ratio, shrinks the instalment against the 30% affordability test, and generally strengthens the application. Even a small deposit can improve your position.
Does pre-approval guarantee my home loan will be approved?
No. A pre-approval certificate is an indication based on the information you supply — it typically lasts 90 days and still depends on the property valuation, your documents checking out, and no change in your financial position. It strengthens your offer because sellers and agents take it seriously.
