Complete Mortgage Guide — South Africa

How Mortgages Work in South Africa

The SARB’s repo rate directly influences the prime lending rate (currently repo + 3.5%), which is the benchmark for all South African home loans. When the SARB changes the repo rate, the prime rate moves by the same amount, and all variable-rate home loans adjust accordingly. South Africa has experienced significant rate volatility, with the prime rate ranging from 7% to 13.75% over the past decade

Types of Mortgages Available

South African home loans are predominantly variable rate, linked to the prime lending rate. The bank quotes a rate as prime minus a concession (e.g. prime minus 0.5%) or prime plus a loading for higher-risk borrowers. Fixed-rate products are available for 2-5 year periods but are uncommon and typically more expensive. Access bonds (similar to offset facilities) allow excess payments to be redrawn. Building loans with progressive drawdowns are used for construction

How Much Can You Borrow?

Banks assess the instalment-to-income ratio, typically requiring that the proposed bond repayment does not exceed 30% of gross income. Total debt commitments including the new bond should not exceed 40-50% of gross income. ITC (credit bureau) checks through TransUnion, Experian, or XDS are critical — any judgements, defaults, or adverse listings will impact approval and pricing significantly

The maximum loan-to-value in South Africa is Up to 100% bond (zero deposit) is genuinely available from all major banks for well-qualified borrowers with clean credit records. This is one of the few markets globally where 100% financing is standard. The pricing difference between 100% and 90% LTV is typically 0.25-0.75% in the interest rate. Transferring costs (bond registration, transfer duty) are separate and must be funded from savings. Loan terms extend up to Maximum 30 years, with 20 years being the most common. Most banks recommend the shortest term affordable, as the variable-rate nature of South African loans means total interest is highly sensitive to rate changes over long periods.

The Application Process

Use a bond originator (free service) to apply to multiple banks simultaneously. Provide SA ID, proof of income (latest 3 payslips, 3 months bank statements), proof of residence, offer to purchase (OTP), and details of existing debts. The bank conducts a property valuation. Pre-qualification takes minutes through originators. Full approval typically takes 3-7 working days. A transferring attorney handles the bond registration at the Deeds Office

Costs and Fees

Bond registration costs include attorney fees and Deeds Office registration — approximately 1-2% of the bond amount. Transfer duty of 0-13% on a sliding scale (properties below R1,100,000 are exempt). Initiation fees of up to R6,037.50 are charged by the bank and can be added to the bond. Monthly service fees of R50-100 apply to the bond account. Early settlement of variable-rate loans carries no penalty — you can pay off your bond at any time without cost

Refinancing Your Mortgage

Since South African home loans are variable rate with no prepayment penalty, you can switch banks at any time without cost (other than new bond registration fees). The process is similar to a new application — use a bond originator to compare current offers. If your financial position has improved since the original application (higher income, better credit score, or lower LTV due to property value growth), you may qualify for a better rate. Banks also offer rate negotiations for existing clients to prevent switching — always negotiate before committing to a transfer

Tips for Getting the Best Deal

Always use a bond originator (BetterBond or ooba) — their service is free and they submit to multiple banks simultaneously, ensuring competitive pricing. Maintain a clean credit record — even a cellphone contract in arrears can impact your rate by 1%+. If offered prime minus a concession, negotiate further — the first offer is rarely the best. Make extra payments whenever possible — at South African rates, even R500/month extra can save hundreds of thousands in interest and cut years off the term. Review your rate against market annually and negotiate or switch
