The 5 C’s of credit are character, capacity, capital, collateral and conditions. Every home loan assessment is a version of those five questions. In our experience capacity is where most declines happen, because lenders test you at your rate plus a 3 percentage point buffer.
Current as at September 2026.
Quick answer: the 5 C’s of credit are character, capacity, capital, collateral and conditions. It’s the framework I was taught at CBA and it’s still the clearest way I know to explain why one application gets approved and another one doesn’t. Every home loan assessment I’ve seen is some version of these five questions.
I learned it at CBA before I started Loan Lounge in 2015 and I still use it to explain a decline to a client, because a client deserves a better explanation than “the computer said no”.
Character: will you pay it back?
This is your track record. In practice it means your credit report (defaults, late payments, how many times you’ve applied for credit recently), how long you’ve been in your job and at your address, and what your recent bank statements say about you.
Lenders read statements more closely than people expect. Regular gambling transactions, a pattern of overdrawn accounts, buy now pay later instalments, a cash advance on a credit card: each one is a question the assessor will ask, and most of the time there’s an answer. Our FAQ page lists what we ask for up front, and it includes six months of statements for existing loans and your most recent credit card, car loan and buy now pay later statements, which is where the character evidence comes from.
A thing I tell people: the few months of statements before you apply are the months the lender sees. If you’re planning to apply in the new year, the spending you do in October matters.
Capacity: can you afford the repayments?
This is the big one and it’s where most declines happen. Capacity is your income minus your commitments minus your living expenses, tested at a rate higher than the one you’ll pay.
That last part surprises people. APRA requires the banks it regulates to assess whether you could still service the loan if your interest rate were 3 percentage points higher than the actual rate. APRA confirmed the 3 point buffer on 28 May 2026. So if your loan is at 6%, you’re being assessed at 9%. With the cash rate at 4.35% after three rises this year, that buffer is doing a lot of work, and on the files we’ve run since February it’s the biggest single reason borrowing capacity has come down.
Living expenses are checked against a benchmark called the Household Expenditure Measure and against your statements. If you declare $2,500 a month and your statements show $4,000, the lender uses $4,000. If you declare $2,500 and the benchmark for a household like yours is $3,200, they’ll generally use $3,200 and may ask questions.
Then there’s the income side, and this is where lender policy varies most. Lenders differ on how much rental income they count, and we work through a recent example in Mortgage broker vs bank. Whether bonus and overtime count in full or are shaded. Whether one year of self-employed returns is enough. Two lenders can give the same person quite different borrowing figures, purely on how they read capacity.
Capital: what have you got behind you?
Your deposit, your savings, your other assets. Capital tells the lender two things: how much skin you have in the deal, and whether you have a buffer if something goes wrong.
The deposit drives the loan to value ratio, and the LVR drives whether you pay lenders mortgage insurance. Above 80% LVR you’ll generally pay LMI, which on a big loan is a lot of money. Our doctors and nurses page quotes a saving of up to $29,500 in LMI, based on an average loan of $750,000 in NSW at 95% LVR, for professions where lenders waive it. That figure gives you a sense of what LMI costs at that loan size.
Since 1 October 2025 the Home Guarantee Scheme has let eligible first home buyers purchase with a 5% deposit and no LMI, with no income cap and a price cap of $1.5 million in NSW. That’s a capital problem solved by a government guarantee, which is why it’s changed the maths for the first home buyers we see. It doesn’t change capacity, which is the point a lot of people miss: a smaller deposit means a bigger loan, and a bigger loan needs more income to service.
Genuine savings matter too. Some lenders want to see that at least part of the deposit was saved over time rather than gifted. Others are relaxed about gifts with a letter from the giver.
Collateral: what is the security worth?

The lender is going to hold a mortgage over it, so they care what it’s worth and how easy it would be to sell.
Lenders get a valuation, and the valuation can come in below the contract price, which is a problem when the deposit was calculated on the contract price. They also have property policies: minimum unit size, restrictions on studios, caution about high density postcodes, mixed use buildings, properties with a commercial premises underneath, homes on very large acreage. A property that’s fine for one lender is declined by another, and it’s the asset being judged.
Our advice on the FAQ page, for NSW purchases, is to pay a 0.25% holding deposit and ask for a 10 day cooling off period when you find a place. That window is for the valuation and for turning a conditional approval into a formal one.
Conditions: what is happening around the loan?
The economic conditions, the purpose of the loan, and anything else the lender takes into account that isn’t about you personally. Interest rates are the obvious one: the cash rate went from 3.60% at the end of 2025 to 4.35% by May 2026, and the assessment rate went up with it. Three of the four major banks were forecasting a further rise before the end of the year as of 1 September.
Purpose is a condition too. An owner-occupier loan and an investment loan on the same property are assessed and priced differently. Lender appetite is a condition: a bank that wants more investor business this quarter will loosen something, and one that’s over-exposed to a postcode will tighten.
How it plays out on a real file
In our files a decline is rarely “all five”. It’s usually one, sometimes two, and capacity is the most common. A capacity decline at one lender can be an approval at another because they weight income differently. A collateral decline is about the property and follows you to every lender that has the same policy, so the fix is a different property or a lender with a different list. A character decline (a recent default, say) is about time, and the honest answer is often “not yet, come back when it’s older and here’s what to do in the meantime”.
That’s why we do a fact find before we do anything else. The fact find is the 5 C’s in questionnaire form. It tells us which C is going to be the problem before a lender sees the file, and which lender’s policy is kindest to that C.
What do the five C’s look like side by side?
| C | What the lender is asking | What they look at |
|---|---|---|
| Character | Will you pay it back? | Credit report, statements, job and address history |
| Capacity | Can you afford it at a higher rate? | Income, debts, living expenses vs HEM, 3 point buffer |
| Capital | What’s your stake and your buffer? | Deposit, savings, LVR, genuine savings |
| Collateral | What’s the security worth and can it be sold? | Valuation, property type, postcode, unit size |
| Conditions | What’s happening around the loan? | Rates, loan purpose, lender appetite |
If you want to know which C is going to be your problem before you apply, that’s about an hour’s conversation and there’s no charge for it (the lender pays us if a loan settles). Call 02 9037 2825 or book a time with one of the brokers.

Frequently Asked Questions: The 5 C’s of Credit, Explained
What are the 5 C’s of credit?
Character, capacity, capital, collateral and conditions: a way of grouping what a lender looks at when it assesses a loan application.
Which of the 5 C’s matters most for a home loan?
Capacity, usually. In our experience most home loan declines come down to whether the applicant can service the loan at the assessment rate, which for the banks APRA regulates is currently the actual rate plus a 3 percentage point buffer.
Can a broker change my 5 C’s?
No. Your income, deposit and credit history are what they are. A broker can find the lender whose policy reads them most favourably and tell you what to fix before you apply.
