Comparing a 6.61% 20-year fixed quote for a Cape Town purchase

The latest quote has created a different comparison problem. For a Cape Town purchase around ZAR 5,551,000, one lender is offering 6.61% fixed over 20 years. The headline rate initially appeared competitive, but fees and the loan-to-value band materially altered the cost.

Should I use APR only as an initial filter, then compare cash outflow over the years we are likely to own the property? Moving before maturity is possible, so the monthly payment, remaining balance, exit charges and conditions for transferring the mortgage may matter more to us than the theoretical 20-year total.
 
If moving early is a realistic possibility, I’d compare total cash outflow up to several plausible sale dates rather than over all 20 years. Include the deposit, monthly payments, fees, remaining balance and any early-repayment cost. APR is still useful as a quick comparison, but it may not reflect your likely holding period particularly well.
 
One detail would change the comparison: is ZAR 5,551,000 the property price or the sum being borrowed? If it is the price, the deposit determines the loan-to-value band and may affect which offer applies.

The fees need two versions in the calculation as well. Paying them in cash raises the amount needed at the start; financing them increases the mortgage balance and generates interest. Compare both consequences over the same likely ownership periods before deciding that the lower quoted rate is cheaper.
 
I wouldn’t push APR too far into the background. It can expose a supposedly cheap rate that is carrying substantial fees. My approach would be APR as the first filter, followed by Clara’s cash-flow comparison for the years in which you might move. Portability only helps if the conditions fit the property and borrowing you would need at that time.
 
Monthly affordability deserves its own test too. A quote can produce the lowest projected total cost while leaving too little room in the household budget. I’d run the payment against normal expenses and a less comfortable income or expense scenario, then decide whether any saving is worth the reduced flexibility.
 
Agreed on affordability, though I would keep it separate from the lender-cost comparison. Otherwise a longer or differently structured loan can appear “better” simply because its payment is lower. Compare like with like first, then stress-test the resulting monthly payment. For an early move scenario, don’t assume refinancing or replacement borrowing will be available on equally favorable terms.
 
The portability wording needs more than a yes/no answer. Ask what must be reassessed when you move, whether the same balance and rate can actually transfer, and what happens if the next property costs more or less. Terms vary, so the lender’s written conditions matter more than the word “portable” in a summary.
 
Thanks, this has helped narrow it down. The ZAR 5,551,000 figure is the purchase price, not the loan amount, so I need to stop comparing examples that assume a different loan-to-value tier. I’m now building two main cases: keeping the mortgage for the full period and selling before the fixed period ends. I’ve also asked for the fee treatment, early-repayment calculation and portability conditions in writing.
 
For those two cases, put every offer into the same simple table: initial loan balance, upfront cash, financed fees, monthly payment, cumulative payments, balance at the assumed sale date and any stated exit cost. That should prevent the lower advertised rate from winning merely because some costs sit elsewhere.
 
One extra distinction: rate-reset risk only belongs in the numbers if the mortgage continues beyond the 20-year fixed period or if your scenario relies on replacing this loan. If 20 years is also the entire repayment term, the bigger uncertainty is the cost of leaving early, not a later reset on this particular quote.
 
Before choosing, ask each lender to rerun its offer using the same loan amount, deposit, repayment term and fee treatment. Then compare the 6.61% quote at your expected holding period and at a couple of earlier exit dates. If one offer wins only under a full 20-year assumption, that is important given your possible move.
