How to refinance a home loan in South Africa

What does refinancing a home loan mean in South Africa?

Refinancing a home loan means replacing your current bond with a new one on better terms — almost always a lower interest rate. Internationally the word is refinance; in South Africa the industry usually calls the same move switching your bond (a new lender) or re-pricing (your current bank improves the rate on the existing bond). A “mortgage” and a “bond” are the same thing — South Africans say bond, so that is the term this guide uses.

A refinance is not a further loan or re-advance, where you borrow extra against the property. In a rate-driven refinance the balance stays the same; what changes is the interest rate charged on it — and often the lender charging it.

Why it works: banks price home loans individually, so the same borrower can get different rates from different banks. When multiple banks quote on your application, the margin below or above prime becomes negotiable — ooba reports an average rate concession of about 0.67% below prime across the bonds it registers (source: ooba Home Loans, verified 03 Oct 2026).

How do you refinance a home loan in South Africa?

You refinance by applying for a new bond at a better rate and letting it replace the old one: check the break-even, get a settlement quote, apply to several banks, pass the valuation and credit assessment, and register at the Deeds Office. The five steps below take most applicants a few weeks from application to registration.

1. Run the break-even maths first. Work out whether the saving beats the once-off costs before you apply. On the worked example below, a R 1 500 000 bond repriced from 11.75% to 10.25% saves about R 1 531 a month and breaks even in roughly 30 months. The free calculator in our break-even guide does this for your own balance.
2. Ask your current bank for a settlement quote. Request a written settlement figure — banks provide it free within five business days under National Credit Act section 113. Check the early-settlement charge: the NCA caps it at 3 months’ interest, reduced by the notice you give (typically 90 days). A fully paid-up bond carries no early-settlement charge.
3. Apply to several banks — through one originator. A bond originator submits one application to multiple banks at once, free to you (the winning lender pays the commission). Multiple banks pricing the same application is what creates a rate concession. You can also ask your current bank to re-price the bond — an internal switch avoids re-registration, but you lose the competition between lenders.
4. Valuation and credit assessment. The new bank values the property and assesses your income, expenses and credit record, then makes a written offer. Offers differ by bank — compare the interest rate, the initiation fee and any conditions side by side before accepting.
5. Registration at the Deeds Office. Bond attorneys cancel the old bond and register the new one at the Deeds Office. This is the slowest step — weeks rather than days — and the once-off fees in the table below fall due here. Your repayment at the new rate starts once the new bond is registered.

What interest rate will you get when you refinance?

South African home loans are priced off the prime lending rate, currently 10.75% (effective 25 Sept 2026, following the 23 September 2026 SARB MPC decision; source: South African Reserve Bank (SARB)). Your offer is prime plus or minus a personal margin set by each bank's assessment of your credit record, affordability and the loan-to-value on the property.

As a range, not a promise: offers across the major-bank panels typically land between prime -1.0% and prime + 2.0% (bond.co.za bank-panel illustration, cross-checked with ooba Home Loans rate-concession reporting, verified 03 Oct 2026). The difference between a weak and a strong offer is exactly the gap a refinance captures — which is why applying to several banks, not one, is the step that moves the number.

Two honesty notes. First, the rate is variable: when the SARB's Monetary Policy Committee moves the repo rate, prime moves with it and so does your instalment. The next MPC decision is scheduled for 19 Nov 2026. Second, transparency about how originators are paid: as a bond originator, bond.co.za is paid commission by the lender you sign with — the comparison and submission are free to you.

What are the disadvantages of refinancing a home loan?

Refinancing costs real money up front and can quietly cost more if you get the structure wrong. Watch these five:

• Once-off costs come first. Attorney, Deeds Office and initiation fees on the new bond (the table above), plus a possible early-settlement charge on the old one — all payable before the saving adds up.
• Restarting the term resets the interest clock. A fresh 20-year term on a bond you have been repaying for years lowers the instalment but raises the total interest. Keep the remaining term unchanged to keep the saving.
• Capitalised costs compound. If the switching costs are added to the new loan instead of paid in cash, you pay interest on them for the rest of the term.
• The advertised rate is not your rate. Every offer depends on the bank's assessment; the rate you switch for is only confirmed in writing after approval.
• Moving soon makes it a loss. If you sell or settle before the break-even month, the switch costs more than it saves — on the maths alone.

Is refinancing the same as switching your bond?

Essentially yes. Bond switching is the South African term for moving your home loan to a new lender at a better rate — what international sites call refinancing. “Refinance” is broader: it also covers re-pricing with your current bank (an internal switch, with no re-registration) and, loosely, further loans against the property. The rates-and-costs mechanics are the same either way.
