Why This Is Different From a Deposit Calculator
Most deposit calculators only tell you when you will have saved 10%. But buying a house requires two conditions to be met simultaneously: you need the deposit AND your income must qualify for the bond. This calculator tracks both in parallel, accounting for:
- Annual salary increases compounding over time
- Savings accumulating month by month
- Potential interest rate changes affecting qualification
- Existing debts reducing your qualifying amount
The Two Qualification Criteria SA Banks Check
1. Deposit availability: Most SA banks require a minimum 10% deposit. While some will lend 100% of the property value, 10% is the practical target. First-time buyers with less than 10% face higher interest rates, mortgage insurance requirements, and stricter credit assessment.
2. Income qualification (DTI): Your gross monthly income must be high enough that the bond repayment (plus all existing debts) does not exceed 30% of gross income. With a current prime rate of 10.25%, the required income rises and falls with rate changes.
Worked Example
Thabo, age 26, earns R28,000/month gross and saves R3,500/month. He has R25,000 saved and owes R2,800/month on a car loan. He wants to buy in the R1,100,000-R1,300,000 range.
For a R1,200,000 property (10% deposit = R120,000, bond = R1,080,000): at 10.25% over 20 years, the monthly bond is approximately R10,660. Total debt: R10,660 + R2,800 = R13,460. At 30% DTI, required income = R13,460 / 0.30 = R44,867/month.
Thabo needs 2 things to improve: his savings to reach R120,000 (about 27 months at R3,500/month) and his income to grow from R28,000 to ~R45,000 (about 34 months at 6%/year). Both criteria are met after approximately 34 months — targeting early 2029.
Frequently Asked Questions
When can I afford to buy a house in South Africa?
You can afford to buy a house when two conditions are met simultaneously: you have saved at least 10% of the property price as a deposit, and your gross monthly income is high enough that the bond repayment plus existing debts does not exceed 30% of your income. The timeline calculator projects exactly when both these conditions will be met, based on your current savings rate and expected salary growth.
How does FLISP speed up the timeline?
The First Home Finance (previously FLISP) subsidy provides a once-off deposit contribution of up to R169,264 for first-time buyers earning between R3,501 and R22,000/month. This is added to your savings, which can significantly accelerate the deposit phase of your timeline — potentially cutting years off the waiting period. You apply for FLISP through your bank when you apply for the home loan.
Should I pay off debt or save for a deposit first?
It depends on your specific situation. High-interest debt (credit cards, personal loans at 20%+) should generally be cleared first — the interest cost exceeds what your savings will earn. Car loans (typically prime + 2-4%) are more of a judgement call. The key insight is that clearing a R3,000/month debt increases your bond qualifying income by R10,000/month (at 30% DTI) — sometimes worth more than the deposit itself. Use the Accelerate tab to compare both strategies with your numbers.
What if interest rates drop before I am ready to buy?
A rate cut benefits you in two ways: it reduces the required monthly repayment (making the income qualification easier) and it may slow property price growth slightly. If the SARB cuts rates by 1% from current levels, the required income to service a R1,080,000 bond drops by approximately R1,800/month — which could pull your qualification date forward by 6-18 months depending on where you are in your income trajectory.
Can a co-borrower (surety) help me qualify sooner?
Yes. Applying jointly with a parent, spouse, or partner combines both incomes for qualification purposes. This is one of the fastest ways to bring the qualification date forward — often immediately, if the co-applicant earns enough. However, both applicants are jointly and severally liable, meaning the co-applicant is fully responsible if you default. Parental surety arrangements should be formally documented with a bond attorney.
