Get inside a lender’s mindset — and structure your deal the smart way.
Understanding how a bank looks at your property puts you a step ahead. Our calculator mirrors the exact logic South African lenders use to size loans — so you can test your deal before you apply and know what to expect when it hits credit.
Banks don’t lend on hopes — they lend on cash flow. Their first question is simple:
“Can this property pay for itself?”
They start with Net Operating Income (NOI) — your rental income after deducting real-world operating costs like:
That’s the figure banks trust, and it’s the same figure our calculator uses. You’ll instantly see how much income your property truly generates in bankable terms.
💡 Tip: Overstating rent or understating expenses can shrink your loan size — our calculator shows that impact in real time.
Once the NOI is clear, banks apply a capitalisation rate (cap rate) to determine market value: Value = Annual NOI ÷ Cap Rate
That single percentage quietly defines what your property is worth to the bank. Our calculator lets you slide the cap rate and watch your valuation update instantly — just like a lender’s internal model.
📈 Prime locations and blue-chip tenants attract lower cap rates — and higher valuations.
Next comes the Debt Service Cover Ratio (DSCR) — a measure of how comfortably your income covers the bond repayment.
Typical thresholds:
Your DSCR effectively caps how much the bank is willing to lend. Our calculator runs this logic automatically, showing the maximum loan your NOI can support under different DSCR targets.
📊 Move the DSCR slider to see how tighter coverage requirements reduce borrowing power.
Two limits, one outcome:
The smaller of the two wins — and that’s your real loan ceiling.
⚖️ Cap rates drive your value. DSCR drives your funding. Our tool shows both — so you can see exactly where your deal tops out.
Running your deal through our calculator gives you:
No forms. No waiting. Just a live, transparent snapshot of how your property performs under true bank logic.
