Frequently Asked Questions About Home Loans in South Africa

How much home loan can I qualify for in South Africa?

Most South African banks use affordability assessments based on income, expenses, existing debt and other financial information. The Lighthouse Bonds calculator applies a 32% net income lending criterion to estimate your qualifying bond amount. Actual approval depends on the lender's full credit and affordability assessment.

What is the maximum bond I can afford on my salary?

As a general rule of thumb, a bond may be approximately 12 to 15 times monthly net income, depending on the interest rate, loan term, existing debt and lender criteria. Use the Lighthouse Bonds qualifier for a more useful affordability estimate based on your financial information.

Can I apply for a joint home loan with my partner?

Yes. A joint bond application combines the applicants' financial information. This can increase the qualifying amount where both applicants have sufficient income and acceptable credit profiles. The Lighthouse Bonds calculator supports joint applicants.

What credit score do I need for a home loan in South Africa?

There is no single credit-score threshold that applies to every lender. A score around 700 or higher is generally regarded as a stronger position, but lenders also consider affordability, debt obligations, payment history and the applicant's overall credit profile.

Is this bond calculator really free?

Yes. The Lighthouse Bonds home loan qualifier is free. The calculator is supplied as a self-contained HTML file that can be used online or offline.

Does the calculator work on mobile?
