Buying a home is one of the biggest financial decisions you’ll ever make — and it all starts with knowing what you can afford. But here’s the catch: many buyers miscalculate their affordability, which can lead to declined bond applications, disappointment, and unnecessary stress.
At Infinity Bonds, we help South Africans make smart, informed property moves every day. Here’s a breakdown of five common affordability mistakes — and how to avoid them.
Overestimating Your Income
The Mistake:
Many buyers assume their full salary (plus bonuses or side hustles) can be used to calculate affordability.
The Reality:
Banks typically assess your net (after-tax) income and may not include irregular earnings like overtime or bonuses unless you can prove consistency over time.
The Fix:
Work with an experienced bond originator to run a realistic affordability check using only the income banks will recognize.
Ignoring Existing Debt
The Mistake:
Thinking, “I only have a small loan or a credit card – it won’t affect my bond.”
The Reality:
Even small monthly repayments (like a R500 store account or R2000 car instalment) impact your debt-to-income ratio, which banks use to assess your ability to repay a bond.
The Fix:
Add up all your current credit obligations before estimating your home loan affordability.
Forgetting About Transfer & Registration Costs
The Mistake:
Assuming the purchase price of the property is the total amount you need.
The Reality:
In most cases, transfer fees, bond registration costs, and legal fees are separate and can add thousands to your upfront expenses.
The Fix:
Ask Infinity Bonds for a breakdown of the full costs involved — we’ll guide you through every hidden fee.
Not Checking Your Credit Score
The Mistake:
Skipping the credit check until after you’ve found a home.
The Reality:
A low or inconsistent credit score can lead to your bond application being rejected — or only approved at a higher interest rate.
The Fix:
Do a credit check early in the process. Infinity Bonds can help you assess and improve your score before applying.
Estimating Without Expert Help
The Mistake:
Using a rough online calculator or personal guess to determine what you can afford.
The Reality:
Every bank uses slightly different criteria. Without comparing across multiple lenders, you might miss a better deal — or worse, apply for the wrong amount.
The Fix:
Let Infinity Bonds do the heavy lifting. We apply to multiple banks on your behalf, for free, and ensure you get the best deal based on your actual financial profile.
Final Thoughts
Buying property is exciting — but jumping in without a clear understanding of your affordability can set you back. Avoid these common mistakes by starting with a proper pre-approval through a trusted bond originator like Infinity Bonds.
