How Much House Can You Afford? A Guide for African Buyers

September 26, 2026

Why Affordability Matters More Than the Asking Price

The biggest mistake first-time buyers make is falling in love with a property they can't afford. Banks use strict criteria to determine how much they'll lend you, and understanding these rules upfront puts you in control.

The 30% Rule

Most banks in Africa follow the 30% rule: your total housing costs (bond repayment, rates, insurance, levies) should not exceed 30% of your gross income. Some banks stretch this to 33%, but conservative lenders stick to 30%.

Example

If you earn R50,000/month:

  • Maximum housing cost: R15,000/month
  • At 11.75% over 20 years, this supports a loan of approximately R1.45 million
  • Add your deposit, and that's your maximum property value

Factors That Affect Your Borrowing Power

Income Stability

Banks prefer stable, documented income. Salaried employees with 6+ months at their current employer get the best terms. Self-employed applicants typically need 2-3 years of financial statements.

Existing Debt

Every rand going to existing debt (car payments, credit cards, personal loans) reduces what's available for a bond. Use our Debt Repayment Calculator to plan paying off debt before applying.

Credit Score

A higher credit score means a better interest rate. Even 0.5% less can save hundreds of thousands over a 20-year bond. Check our guide on Understanding Credit Scores in Africa.

Deposit Size

A 10-20% deposit significantly improves your chances and reduces monthly payments. Start saving early with our Savings Goal Calculator.
