Is it worth refinancing your home loan in South Africa right now?

Refinancing — switching your home loan to a new bank for a better rate — isn't automatically worth it just because South Africa's prime rate is 10.75%. bond.co.za's own calculation: a switch needs roughly a half-point rate gap on a mid-sized bond to clear its registration costs within about two years; below that, switching rarely pays for itself.

Key takeaways

  • 01South Africa's prime lending rate has risen 0.50 percentage points in 2026 so far — from 10.25% to 10.75% — across 2 SARB MPC hikes this year. That is bond.co.za's own tally of the year's MPC decisions, and it is the backdrop against which any refinancing decision is now being made.
  • 02Refinancing does not become automatically worth it just because prime is higher. A rate gap of roughly 0.50 percentage points — a realistic size when shopping a bond around — is worth more in rand terms at today's 10.75% prime than it was before this year's hikes, but it still has to clear real registration costs before it pays off.
  • 03On an illustrative R 1 500 000 bond, that gap is worth R 514 a month. New bond registration costs on the same example come to roughly R 45 306, so the saving only clears those costs after about 88 months.
  • 04Refinancing is a new credit application, not a transfer of your existing one — the new bank reassesses your income, expenses and credit record from scratch, and orders its own property valuation.
  • 05Before paying to switch, ask your current bank if it will match the new offer. Many will, specifically to avoid losing your business — and doing so skips the registration costs entirely.

Is it worth refinancing your home loan right now?

It depends on the size of the rate gap you can actually get, your outstanding balance, your remaining term, and how long you plan to keep the property — not on whether prime has gone up or down. What changes after 2 MPC hikes this year is the base the gap is added to: at today's 10.75% prime rate (SARB, effective 2026-09-25), the same 0.50 percentage point gap between a current rate and a better offer is worth more in rand terms than it was before prime reached 10.75%.

Here is bond.co.za's own calculation, computed from the standard South African annuity formula, comparing a bond currently priced at 11.50% against a more competitive offer of 11.00% — a realistic size of gap when shopping a bond around, not a guaranteed quote — over a 20-year term:

Bond sizeMonthly at 11.50%Monthly at 11.00%Monthly saving
R 900 000R 9 598R 9 290R 308
R 1 500 000R 15 996R 15 483R 514
R 2 500 000R 26 661R 25 805R 856

On the R 1 500 000 bond, that gap is worth R 514 a month — R 123 268 over the full 20-year term — before weighing up what switching itself costs. To run this against your own bond size, use the bond repayment calculator.

What happens when you refinance a home loan?

Refinancing (also called bond switching) is a new credit application and a new bond registration, not a transfer of your existing one. A new lender reassesses your income, expenses and credit record, orders its own property valuation, and — if it approves the application — registers a new bond at the Deeds Office while your old bond is settled and cancelled, usually coordinated to happen together. There is no transfer duty, because ownership of the property does not change; only the bond over it does.

On the same R 1 500 000 example, the new bond registration side comes to:

CostAmount
Bond attorney (conveyancing) fee, incl. VATR 37 530
Deeds Office bond registration feeR 1 738
Bank initiation fee, incl. VATR 6 038

That is roughly R 45 306 in new-bond registration costs on a R 1 500 000 bond. Set against the R 514 monthly saving from the 0.50 percentage point scenario above, the saving only clears those costs after about 88 months — before that point, the switch is still costing more than it has saved. You may also face early-settlement or notice costs on your old bond; your current bank sets those terms, so confirm them directly before committing to a switch date.

What are the disadvantages of refinancing a home loan?

  • A full new credit and affordability assessment happens regardless of your track record on the existing bond — a stronger offer is not guaranteed.
  • New bond registration costs (attorney, Deeds Office and bank initiation fees) are due once the new bond registers, whether or not the rate gap ends up being worth it in hindsight.
  • Your current bank may match or beat the new offer once you ask — in which case the switching costs above were never necessary.
  • A short remaining term, or plans to sell soon, can mean the monthly saving never has time to outweigh the upfront costs.

Frequently asked questions

How can I refinance my house loan in South Africa?

Apply to a new lender — directly, or through a bond originator submitting one application to multiple banks at once. The new bank reassesses your affordability and credit record, orders a fresh valuation, and if it approves the application, issues a new home-loan offer. You then give your current bank notice, and bond attorneys appointed by the new bank register the new bond and settle the old one, typically coordinated to happen on the same day.

What's the downside to refinancing a home loan?

The main downside is cost and effort for an uncertain payoff: new bond registration costs (attorney, Deeds Office and bank initiation fees) are due regardless of how long you keep the new bond, a fresh credit and affordability check can go either way, and your current bank may simply match the new offer once asked — making the switch unnecessary. It is worth running the actual numbers before committing, not assuming a lower advertised rate automatically wins.
