What is Bridging Finance in South Africa?
Bridging finance (also called a bridge loan or swing loan) is a short-term loan used to cover the gap between buying a new property and receiving the proceeds from selling your existing property. It "bridges" the funding gap when both transactions don't complete simultaneously.
In South Africa, property transfers typically take 6–12 weeks to complete. If you need the equity from your existing home to fund the deposit on your new home, and the two transfers don't coincide, you may need bridging finance.
Bridging finance is typically offered at prime + 2–4% — currently 12.25–14.25% per year. It is interest-only during the bridging period.
When is Bridging Finance Needed?
- You've made an offer on a new property that has been accepted, but your current home hasn't sold yet.
- Your current property has a buyer, but the transfer dates don't align — the new property registers before the old one.
- You need the equity from your existing home for the deposit on the new property.
- You want to avoid renting between properties (double moving, storage costs).
Worked Example: Nomsa Upgrading in Johannesburg
Nomsa owns a R1,500,000 home in Johannesburg with a R500,000 outstanding bond. Her net equity is R1,000,000.
She buys a new R2,000,000 home with a 20% deposit (R400,000) and bonds the remainder (R1,600,000 at 10.25% over 20 years = R15,354/month).
The deposit of R400,000 is less than her net equity (R1,000,000), so she doesn't need bridging finance in this case — once her old home sells, she'll have surplus funds.
But if she required a 50% deposit (R1,000,000) and her sale takes 3 months longer than expected: Bridging needed = R1,000,000 − R1,000,000 (net equity once sold) = R0 (still covered). But during those 3 months she's paying R1,600,000 × 12.25% / 12 = R16,333/month on bridging + R15,354 on new bond = R31,687/month total.
Alternatives to Bridging Finance
- Subject-to-sale offer: Make your offer to purchase the new property subject to the sale of your existing property. Sellers may accept this in a slow market.
- Access bond facility: If you have a significant paid-up balance in your existing bond, you may be able to draw against it for the deposit.
- Negotiate transfer dates: Work with your conveyancer to try to synchronise the transfer dates of both properties.
- Rent before buying: Sell your existing home first, rent temporarily, then buy — avoiding bridging entirely (though double moves are inconvenient).
Frequently Asked Questions
What is bridging finance in South African property?
Bridging finance is a short-term loan used to fund the gap between buying a new home and receiving proceeds from selling your existing property. In South Africa it typically costs prime + 2–4% per year (currently 12.25–14.25%) and is structured as interest-only until repaid from the sale proceeds.
How long can you have bridging finance in South Africa?
Bridging finance is intended to be short-term — typically 1–12 months. Most lenders expect repayment within 3–6 months once the existing property transfers. If your existing property takes longer to sell, costs escalate quickly. Many banks set a maximum term of 12 months, after which you may need to renegotiate or refinance.
Which banks offer bridging finance in South Africa?
All major South African banks (ABSA, FNB, Nedbank, Standard Bank, Investec) offer bridging finance products. Specialist bridging finance companies and bond originators (like ooba, BetterBond) also arrange bridging facilities. Rates and terms vary — compare multiple lenders and factor in initiation fees, which can add 1–2% to the effective cost.
Can I get bridging finance if my property hasn't sold yet?
Yes, but it is harder. Most lenders prefer to see a signed sale agreement on your existing property before providing bridging finance. Without a confirmed sale, the risk is higher and the lender may require additional security (like a letter of undertaking from the conveyancing attorney) or may decline. Some specialist bridging companies do provide "open-ended" bridging at a premium rate.
What are the risks of bridging finance in South Africa?
Key risks: (1) Your existing property takes longer to sell than expected, running up bridging costs; (2) Your buyer's bond is declined, the sale falls through, and you're stuck with two properties and bridging costs; (3) Property values fall, your existing property sells for less than expected, leaving a shortfall. Always have a contingency plan and ensure your existing property is priced correctly for a quick sale.
