What is a Bond?

In South Africa, a bond or home loan refers to the money that a bank or financial institution lends to an individual for the purpose of purchasing a property. This type of loan is secured against the property itself, meaning that if the borrower fails to make the agreed repayments, the lender has the right to take possession of the property to recover the outstanding debt. Here’s a more detailed look at how it works:

Interest Rates

  • Fixed Rate: The interest rate remains the same throughout a certain period of the loan term, offering stability in repayment amounts.
  • Variable Rate: The interest rate can fluctuate based on the prime lending rate, affecting monthly repayment amounts.


  • Amortization: Home loans are typically repaid in monthly installments over a set period (e.g., 20 or 30 years), which includes both the principal amount and interest.
  • Early Repayment: Borrowers may have the option to pay off their loan early, either in part or in full, which can save on interest but may incur penalties depending on the terms of the loan.

Types of Bonds

  • Access Bond: Allows borrowers to withdraw additional funds up to the original loan amount, offering flexibility to access surplus repayments.
  • Building Loan: Specifically designed for those building a new home, disbursing funds in stages as construction progresses.

Application Process

  1. Pre-approval: Potential borrowers can get pre-approved for a loan, giving them an idea of how much they can afford before property hunting.
  2. Application: Involves submitting various documents, including proof of income, identity, and details about the property.
  3. Approval and Transfer: Once approved, the loan amount is transferred to the seller or developer, and the property is registered in the borrower’s name, subject to the bond being registered as security for the loan.

Costs Involved

  • Deposit: A percentage of the purchase price (usually 10-20%) that the buyer needs to pay upfront.
  • Initiation Fee: Charged by the lender to initiate the loan.
  • Legal Fees: For the registration of the bond and transfer of the property.
  • Valuation Fee: For the bank’s valuation of the property to ensure it’s worth the loan amount.


The National Credit Act (NCA) regulates the issuance of home loans in South Africa, ensuring fair lending practices and protecting consumers from being over-indebted.

Bonds or home loans in South Africa are a common way for individuals to finance the purchase of property, whether for personal use or as an investment. The process and products available can vary, so it’s advisable to consult with financial institutions or mortgage brokers to find the best option suited to one’s financial situation.
