Estimates, not quotes — your rate and approval depend on the bank's assessment. The basics ## What is a building loan — and how is it different from a normal home loan? A building loan pays your builder in stages against a construction contract; a normal home loan pays the seller once, at transfer. Renovation finance changes a home you already own. The documents, costs and risks differ for each. Normal home loan The bank pays out the full loan amount in one go when the transfer and bond register at the Deeds Office. You start paying the full instalment immediately, and the property already exists to secure the loan. Building loan The approved amount is paid out in stages as construction progresses — you only pay interest on what has actually been drawn. The loan only becomes a normal amortising bond once the build is complete and signed off. Renovation loan or further advance For changes to an existing home you already own or are buying. A further advance adds to your current bond; some buyers fund smaller renovations from savings or an access bond instead. This guide covers the **building loan**: financing the construction of a new home, whether on land you are buying or already own. If you are changing an existing home, that is a renovation or further advance instead. The mechanics ## How do building-loan progress payments actually work? The bank never hands over a lump sum — it pays your builder stage by stage, after each inspection is signed off. 01 Foundations and substructure The first draw pays for site preparation, foundations and the slab. The bank’s valuer inspects before this stage is signed off. 02 Wall plate / superstructure Once the brickwork or frame reaches the specified height, the next portion is released to the builder. 03 Roof on The roof structure and covering unlock the following stage payment after inspection. 04 Lock-up Windows, doors and external finishes make the structure secure and weather-tight — another certified draw point. 05 Finishes and completion Plastering, plumbing, electrical, flooring and final finishes. The last payment follows the completion inspection and the issuing of the occupation or compliance certificate. ### What that means for your monthly payment Illustration only: an approved building loan of R 1 200 000 at prime (10.75%, last updated 2026-09-23), over 20 years. Your actual rate and approval depend on the bank's assessment — this is not a quote. While only the first draw (R 300 000) is out≈ R 2 688 / monthInterest only, on drawn amounts Once fully drawn and converted≈ R 12 183 / monthPrincipal + interest over 20 years During constructionSteps up with each drawEach stage payment increases the interest-only amount Source: [South African Reserve Bank (SARB)](https://www.resbank.co.za/en/home/publications/publication-detail-pages/statements/monetary-policy-statements/2026/september). The instalment cap banks apply under the NCA is 30% of gross income — see [today’s prime rate](https://bond.co.za/prime-interest-rate-south-africa-today). Two rules protect you here: the bank pays the builder directly per certified stage — never you, never in advance — and its valuer inspects before each draw is released. You should still visit the site and compare progress against the building contract at every stage.

Two questions, no contact details — an estimated bond range and repayment at today's prime, before you sign a building contract. Gross monthly household income Deposit you plan to put down Qualifying ## What do banks require before they grant a building loan? On top of the normal affordability assessment, they require approved plans, an NHBRC-registered builder, a fixed-price contract and a valuer's view of the finished home. Approved municipal building plans Banks fund what the municipality has approved. Unapproved additions or designs that differ from the approved plans can stall drawdowns or reduce the final payout. An NHBRC-registered builder New homes must be enrolled with the National Home Builders Registration Council (NHBRC) and built by a registered builder — it is a legal protection for you and a standard bank condition. Enrol the home before construction starts. A fixed-price building contract Banks strongly prefer a written, fixed-price building agreement with the builder over open-ended arrangements. Cost-plus deals are harder to finance and shift overrun risk to you. A detailed cost breakdown The builder’s quote should break the price into stages and materials, with a schedule of finishes. The bank prices the loan against this — and pays per stage. A valuer’s view of the finished home The bank lends against the lower of the total building cost or the valuer’s estimate of the completed property’s value. That protects the bank — and you — from overpaying for the build. Your affordability — plus your own contribution Income, expenses and credit are assessed exactly as for a normal bond. Many banks also expect you to contribute equity — often by owning the land outright or putting down a deposit — and to keep cash in reserve for extras and overruns. Exact criteria, deposit expectations and draw schedules differ from bank to bank. Confirm the details with your lender before you sign a building contract — and see the [pre-approval guide](https://bond.co.za/home-loans/pre-approval) for how to lock in your price range first. Paperwork ## Which documents does a building loan need beyond a normal bond? Your ID, payslips and bank statements as usual, plus approved building plans, an NHBRC enrolment certificate and a fixed-price building contract with a stage-by-stage quote. Personal and income (as for any home loan) - South African ID or permanent-residence permit - Latest 3 months payslips and bank statements (more if self-employed) - Proof of current residential address (not older than 3 months) - Details of existing debts and monthly expenses Land, plans and property - Title deed or signed offer to purchase for the land - Approved building plans from the municipality - NHBRC enrolment certificate for the new home - Water, electricity and access confirmations where required Builder and contract - Fixed-price building agreement with the builder - Detailed quote with stage-by-stage cost breakdown - Schedule of finishes (flooring, sanitaryware, fittings) - Builder’s NHBRC registration details The full checklist, with what banks ask for at each draw, is in the free Building Loan Document & Progress-Payment Pack at the top of this page. Costs ## How much cash does a building loan not cover? The bond finances the land and the building contract. On a R 650 000 land purchase with a R 500 000 bond, budget about R 49 268 upfront — and construction-side extras come on top. Financed by the bond (usually) - The land purchase price - The fixed-price building contract - Sometimes a portion of connection and professional fees — per the bank Cash you should budget (usually) - Transfer duty on the land and transfer attorney fees - Bond registration attorney and Deeds Office fees - Municipal plan approval and NHBRC enrolment fees - Water, electricity and sewer connection fees - Professional fees (architect, engineer) if not in the contract - A contingency for overruns — non-negotiable on a build ### Worked example: buying the land for R 650 000 Bond of R 500 000. The same transfer and bond registration costs that apply to an existing home apply to the land — construction-side costs come on top. SARS transfer dutyR 0 Transfer attorney fee (incl.

Neither is universally better — it depends on whether you are optimising for time, cost certainty, cash flow or control over the result. Time to move in An existing home transfers within weeks of registration; a build adds the full construction period on top. If you need to move by a date, a building loan is the riskier route. Cost certainty An existing home has a fixed price on the OTP. A build has a contract price plus real overrun risk — a contingency buffer is not optional. Cash flow during the process Buying existing: bond and transfer costs, then the full instalment. Building: bond and transfer costs on the land, then interest-only instalments that step up as draws progress. What you get A build gives you the layout, finishes and location you choose — often the only way to get exactly what you want, or to build in an area with no stock. An existing home trades that control for speed and certainty. Whichever route you take, the affordability assessment is the same: the bank applies its NCA affordability test to your income, expenses and credit record. Use the [affordability calculator](https://bond.co.za/home-loan-affordability-calculator) to see what instalment range your budget supports before you commit to either path. Watch out ## Where do building-loan buyers get tripped up? Four recurring patterns — cost-plus overruns, paying the builder ahead of the bank, unapproved extras and assuming everything is financed. Cost-plus overruns If your contract lets the builder charge actual cost plus a margin, every overrun lands on you — in cash, because the bank will not simply extend the approved amount. Paying the builder ahead of the bank The bank pays the builder per certified stage. If you pay deposits or advances out of pocket hoping to be reimbursed, you may never see that money again if the build fails. Extras outside the approved amount Upgrades chosen mid-build — better finishes, a double garage, a pool — are your cash unless the bank approves a variation before the money is spent. Assuming 100% of everything is financed The bond may cover the land and building contract, but plan approval fees, NHBRC enrolment, connection fees, professional fees and a contingency are usually cash items. If your situation is anything other than textbook — self-employed income, a cost-plus contract, buying land in an estate or a rural area — talk to your lender or a qualified financial adviser before you sign anything. The cheapest time to find a problem is before the OTP.

FAQ ## Straight answers on building loans Do I pay the full home loan instalment while my house is being built?+ No. During construction you pay interest only on the amounts the bank has actually paid out to the builder. As each progress draw happens, the interest portion grows. Once the build is complete and the final inspection has passed, the loan converts to a normal bond and you pay the full principal-and-interest instalment. Can I get a building loan if I already own the land?+ Yes — and it is often simpler. Owning the land outright means no land purchase to finance and the land's value can count as your contribution. You will still go through a normal affordability assessment, and the bank will still require approved plans, an NHBRC-registered builder, a fixed-price building contract and a valuer's completed-value estimate. What is the NHBRC and why do banks require it?+ The National Home Builders Registration Council (NHBRC) is the body that registers home builders and enrols new homes under South Africa's housing consumer protection scheme. Enrolment gives you a structural warranty on the new home. Banks make enrolment and a registered builder standard conditions of a building loan — build before enrolling and you risk the warranty and the financing. Can I act as my own builder (owner-builder)?+ It is the exception rather than the rule. Most banks want an NHBRC-registered builder under a fixed-price contract, because that is what the warranty scheme and the staged payment model are built around. Financing a self-managed build usually means a far smaller loan-to-value, if a bank will consider it at all. What is the difference between a building loan and a renovation loan?+ A building loan finances the construction of a new home, paid out in progress draws. A renovation is changes to an existing home, usually funded with a further advance on your bond, an access-bond withdrawal or savings. The paperwork, pricing and risk profile are different — do not apply for one expecting the other. What happens if my build costs more than the approved amount?+ The approved amount is the ceiling. If the build overruns, the extra cash comes from you — the bank will not automatically extend the loan. That is why a fixed-price contract, a detailed quote and a personal contingency reserve matter. If you want upgrades mid-build, ask the bank to approve a variation before committing the money. How long does the building-loan process take?+ The approval itself works like a normal bond: an affordability estimate is instant, feedback takes days and formal approval typically takes a few working weeks once documents are in. The build itself then adds the full construction period. Registering the land transfer and bond follows the usual attorney and Deeds Office process. ## Informational disclaimer This guide is for information purposes only and does not constitute financial advice.
