In short
Switching your home loan - a bond switch, or refinancing - means moving your outstanding mortgage from your current bank to a new lender offering better terms. It is one of the few financial moves that can cut a four-figure monthly commitment without changing anything about how you live. It is also one of the most misunderstood, because the headline saving is easy to see and the switching costs are not. A new bond has to be registered at the Deeds Office by attorneys, the existing bond has to be cancelled with 90 days' written notice, and the property has to be valued again - and you carry most of those costs upfront.
The numbers decide it. On a bond of R1.2 million with 20 years left, half a percentage point off your rate saves roughly R400 a month, which is real money, but it takes about six years to earn back R30 000 of switching costs. A full percentage point pays for itself in closer to three. This guide sets out what a switch costs in rand, how the process runs from first quote to first new instalment, where the genuine advantages and the honest drawbacks sit, and the break-even test that tells you whether the move is worth making - including the free phone call to your current bank that sometimes makes the whole exercise unnecessary.
The cost side
A better rate is only the gross saving. These are the charges that sit between you and the net benefit - budget for all of them before you decide.
The largest single cost, and it scales with the size of your bond.
The new lender appoints a bond attorney to register a fresh bond over your property at the Deeds Office. The fees follow a recommended tariff linked to the bond amount, plus Deeds Office lodgement charges, VAT and small disbursements such as postage and searches. On a bond around R1 million, budget in the region of R25 000 to R30 000 all in. It is worth asking every lender you approach whether it is running a switching promotion - banks periodically offer to carry part or all of the registration cost to win the account, and that single concession can change the entire calculation.
Your outgoing bank must be given 90 days' written notice, or it charges you for the shortfall.
Cancelling a registered bond is a legal process handled by a cancellation attorney appointed by your current bank, and the fee typically runs to a few thousand rand. More importantly, South African home loan agreements require 90 days' written notice of cancellation. Give less, and the bank is entitled to charge interest for the balance of the notice period - on a large bond that penalty can run into thousands. Send the notice in writing the moment you are serious about switching; you can withdraw it if the switch falls through.
The new bank will value your home before it will price the loan.
No lender will register a bond over a property it has not assessed. Some banks absorb the valuation cost as part of the application, others pass on a fee of roughly R1 500 to R3 500. Either way the valuation matters beyond the fee itself: it fixes your loan-to-value ratio, and if your property has appreciated since you bought it, a lower loan-to-value is one of the strongest arguments for a better rate. If the valuation comes in below expectation, the offer can be repriced or withdrawn.
A once-off charge for opening the new credit agreement, capped by the National Credit Act.
Every credit provider may charge an initiation fee, and the National Credit Act sets the ceiling. On a mortgage agreement that cap works out to roughly R6 000 including VAT at the upper end. It can usually be added to the loan rather than paid in cash, but adding it means paying interest on it for the life of the bond - so settle it upfront if you can. A small monthly service fee on the new bond account also applies, as it did on the old one.
The hidden cost is agreeing to a lower instalment bought with more years.
A switch is a full credit application: payslips, bank statements, an ID copy, proof of residence and your existing bond statements, followed by a wait of two to six weeks for registration. That is manageable. The real trap is accepting a new 20-year term on a bond that had only 12 years left. The instalment falls, which feels like winning, but you have added eight years of interest to a debt you were close to clearing. Ask the new lender to match your remaining term, and compare total repayment in rand rather than the monthly figure.
Switching a bond can save real money or cost it, depending on the fees. Jacob has checked that the cancellation and registration costs are included in the sums here.
The process
From the first quote to your first instalment at the new bank, a switch usually takes four to eight weeks. Knowing the order of events keeps you in control of it.
Request a statement from your current bank showing your outstanding balance, your exact interest rate, the remaining term and any early settlement conditions.
Most homeowners can name their instalment but not their rate. You cannot judge an offer without the number you are being offered an improvement on. While you are on the call, ask your bank directly whether it will review your rate - it costs nothing, it takes minutes, and a bank that would rather keep your account sometimes concedes a reduction on the spot. If it does, you have saved yourself the entire switching cost.
Your rate is priced on the profile you have today, not the one you had when you bought the house.
You are entitled to a free credit report each year from the registered credit bureaus. Pull it, confirm there are no errors or accounts you do not recognise, and settle or reduce small revolving balances before you apply. Several years of clean bond repayments plus a stronger income is exactly the change that earns a lower margin - but only if the record shows it.
Approach multiple NCR-registered credit providers, or use a bond originator to submit one application to several banks at once.
Rates are quoted against the prime lending rate - prime minus a margin if your profile is strong, prime plus a margin if it is not. Ask each lender for the rate, the initiation fee, the monthly service fee, the term offered and an estimate of the registration cost, in writing. Submitting applications within a short window limits the effect of multiple credit enquiries on your record.
Divide the total switching cost by the monthly saving. The answer is how many months you must stay to come out ahead.
If switching costs R28 000 and the new instalment is R650 lower, you break even after about 43 months. Stay longer than that and every month is profit; sell or move sooner and the switch cost you money. Compare on the same remaining term, and confirm both offers are quoted on a reducing balance so you are comparing like with like.
Submit the full application to your chosen lender, and send your current bank 90 days' written notice of cancellation.
You will need recent payslips, three to six months of bank statements, a certified ID copy, proof of residence and your latest bond statement. Once the new bank issues an approval in principle, the property valuation is instructed. Time the 90-day notice so it expires close to the registration date - too early and you may face a penalty, too late and the transfer stalls.
Attorneys register the new bond and cancel the old one on the same day at the Deeds Office, and repayment starts under the new terms.
The new bank's bond attorney and your old bank's cancellation attorney lodge together, so there is no gap in security and no moment when the property is unbonded. Expect two to six weeks in the Deeds Office depending on the registry. Once registration goes through, confirm your first debit order date, cancel the old one only after the final settlement has cleared, and keep paying the higher old instalment into the new bond if you can - the extra capital shortens the term and is where the real saving compounds.
The honest balance
Refinancing is not automatically the smart move. It rewards borrowers with a long horizon and a materially better offer, and punishes those who switch for a small margin or are close to paying the bond off.
Arguments for switching
A bond is the longest debt most South Africans carry, so even a modest reduction in the rate is multiplied across hundreds of instalments. On R1.2 million over 20 years, one percentage point is roughly R805 a month and close to R190 000 over the full term. No other household saving of that size is available from a single application.
The margin you were given as a first-time buyer reflected the risk you presented then. Several years of perfect repayments, a higher income and a property that has appreciated all reduce the lender's risk - but your existing bank has no obligation to reprice you for it. A switch is how you convert an improved profile into a better rate.
A switch is a natural moment to add an access bond facility, register a slightly larger bond to fund renovations, or consolidate expensive short-term debt into secured credit at a fraction of the rate. Done deliberately, and with the term kept in check, that restructuring can matter more than the rate itself.
Arguments against
Registration, cancellation, valuation and initiation charges are payable now, while the benefit trickles in month by month. If you might sell, emigrate or move within the next few years, you will very likely pay more to switch than you ever recover.
With five or six years left on the bond, most of your instalment is already capital rather than interest, so a lower rate moves very little. Switching at that stage rarely covers its own cost - and stretching the term back out to make the instalment look attractive simply reintroduces the interest you had almost escaped.
A switch is assessed like any new credit application under the National Credit Act, including a full affordability assessment. If your income has become irregular, your debt levels have risen or the valuation disappoints, you may be offered a worse rate than you already have - or declined after already paying for the valuation.
The deciding test
There is a rough rule of thumb that a switch becomes worth investigating once a competing lender can beat your current rate by around half a percentage point and you intend to stay in the property for at least another five years. Treat it as a starting point rather than an answer, because the honest test is always your own break-even figure: total switching cost divided by the monthly saving.
Two things are worth knowing before you commit. First, no transfer duty is payable on a bond switch - ownership of the property does not change, only the bond over it, so the largest cost of buying a home does not apply here. Second, phone your existing bank first. Retaining a performing bond is cheaper for a lender than acquiring a new one, and a documented offer from a competitor is the strongest negotiating position you will ever have. If your own bank matches the rate, you keep the saving without paying a cent in attorney fees. If it refuses, you have lost nothing and you already know the switch is worth making.
Questions and answers
The details that decide whether a switch is worth it are rarely in the advertisement. These are the points worth settling before you sign anything.
Allow four to eight weeks. Credit approval and the property valuation typically take one to two weeks, and registration at the Deeds Office adds another two to six weeks depending on how busy the registry is. The 90-day cancellation notice to your current bank runs alongside this, so send it as soon as you are committed rather than waiting for approval.
South African home loan agreements require 90 days' written notice to cancel. If you cancel with less, the bank is entitled to charge interest for the remainder of the notice period, which on a large bond can amount to several thousand rand. Submit the notice in writing and keep proof of the date - you can always withdraw it if the switch does not proceed.
Yes. If your property has appreciated, you can register a bond larger than the amount you still owe and take the difference in cash, subject to affordability and the lender's loan-to-value limits. It is a cost-effective way to fund renovations or clear expensive unsecured debt, but remember you are converting short-term debt into a commitment secured by your home and repaid over decades.
Applying creates a credit enquiry on your record and the new account is reported once registered, so there is a small short-term effect. Submitting all your applications within a short window keeps the impact minimal, and a well-managed new bond strengthens your record over time. A switch that materially improves your affordability is a net positive for your credit profile.
Always ask your own bank first - it is free, immediate, and it costs a lender less to keep a performing bond than to win a new one. Get a written quote from a competitor before you call, because that is what gives the request weight. Switch only when your bank declines to match and the break-even calculation still works in your favour.
