South Africa Mortgage Guide 2026: Prime-Linked Rates, Bonds, and Transfer Duties

Lending in South Africa is governed less by hard LTV caps and more by strict affordability assessments under the NCA to prevent reckless lending.

Loan-to-Value (LTV) Limits

First-Time Buyers: Maximum 100% LTV is widely available. Banks frequently finance the entire purchase price. First-time buyers with strong credit can sometimes get a 105% LTV loan to cover closing costs (transfer duties and bond registration fees), though this attracts a higher interest rate.

Foreigners / Non-Residents: Maximum 50% LTV. Non-residents must bring at least 50% of the purchase price into South Africa from an offshore account.

Debt-to-Income (DTI) Limit (Affordability Assessment)

Banks strictly adhere to the NCA guidelines. Your mortgage payment generally cannot exceed 30% of your gross monthly income.

More importantly, banks conduct a Net Surplus calculation: Gross Income minus Statutory Deductions (Tax, UIF) minus Living Expenses minus Existing Debt Obligations. If the net surplus cannot cover the new mortgage payment (stress-tested against future rate hikes), the loan is declined.

Use the affordability calculator to determine your maximum mortgage based on the strict 30% DTI limit and net surplus rules.

Variable Rate (Prime-Linked): The overwhelming majority (over 90%) of South African home loans are variable. The interest rate is quoted as Prime plus or minus a margin (e.g., Prime - 0.50% or Prime + 1.00%). When the SARB changes the repo rate, the Prime rate changes immediately, altering your monthly installment.

Fixed Rate: You can usually fix your rate for 1 to 5 years. However, in South Africa, fixed rates are typically offered at a premium (higher than the current variable rate) to price in the bank's future risk. Because of this premium, most buyers stick to variable rates.

Following SARB rate adjustments, the Prime Lending Rate is the benchmark.

Closing costs in South Africa are substantial, primarily driven by the progressive Transfer Duty and high legal fees (conveyancing).

Properties under R1,100,000 are completely exempt from Transfer Duty.

R1,100,001 to R1,512,500: 3% of the value above R1.1m.

R1,512,501 to R2,117,500: R12,375 + 6% of the value above R1.512m.

The scale progresses up to 13% for properties over R12.1 million.

You must pay two separate sets of attorneys:

Total Cash Needed: Budget exactly 4% to 8% of the property price for closing costs (unless the property is under R1.1m, which drastically reduces the cash requirement). Use the budget calculator for a complete estimate.

A highly popular feature. It allows you to pay extra money into your home loan to reduce the capital balance (and thus the interest charged), while retaining the right to withdraw those extra funds later if you need cash. It effectively acts as a high-interest savings account.

Under Section 125 of the National Credit Act (NCA), borrowers who intend to pay off and cancel their mortgage bond early (for example, upon the sale of the home or refinancing to another credit provider) must serve their mortgage lender with 90 days of written cancellation notice. If this statutory 90-day notice is omitted or waived by the borrower to expedite Deeds Office cancellation, the lending bank is legally entitled to charge an early termination penalty interest fee equivalent to the shortfall of the 90-day period.
