Why Stable Rates Still Get Buyers Declined

This episode breaks down why buyers are still being declined even as rates stabilize, from bonus income treatment and living-expense assumptions to strict serviceability tests. It also explains why mortgage advisors now handle most new lending and why relying on one bank can cost buyers their deal.


Chapter 1

The August 2026 Rate Stability Trap

Denese Konowe

I was looking at the latest numbers from August 2026, Lee, and it is unbelievable how many buyers are getting caught in this exact trap. They see interest rates stabilizing, they assume getting a mortgage is simple again, and then, boom, their own bank turns them down cold.

Dr Lee Konowe

Turned down cold. It is, it is the classic baseline mistake. People confuse headline rate stability with lending ease, but mathematically, those two things have almost zero correlation in current bank assessment models.

Denese Konowe

Exactly! I had a couple in Remuera just last month, solid income, sixty thousand dollar deposit saved up, perfect repayment history with their main bank for seven years. They signed a conditional contract on a townhouse, walked into their branch, and got a flat no because one partner gets twenty percent of their income as a quarterly bonus.

Dr Lee Konowe

Ah, the bonus treatment model. See, Bank A might haircut variable bonus income by fifty percent or ignore it completely if it has not been consistent for two full financial years, whereas Bank B down the street might shade it at only twenty percent if the employer provides a single letter of confirmation.

Denese Konowe

And that couple was ready to cancel the agreement! They thought they were financially unfeasible. They were literally sitting in my office in tears, ready to forfeit their dream home because their main bank's computer algorithm flagged their discretionary household spending baseline at five hundred dollars higher than their actual bank statements showed.

Dr Lee Konowe

Well, because the risk assessment algorithms at the major lenders are testing serviceability at stress rates well above current market figures, sometimes test rates exceeding eight or eight point five percent. So a three hundred dollar difference in standardized living expense assumptions completely wipes out their calculated borrowing buffer.

Denese Konowe

It is a policy mismatch, pure and simple, not a personal financial failure. We got them to a broker, and within forty eight hours, another main bank approved them with room to spare.

Chapter 2

The 70% Shift: Why Single-Bank Loyalty Is Dead

Dr Lee Konowe

Which explains precisely why single bank loyalty in New Zealand is essentially dead and buried. Did you see the latest market share figures? Mortgage advisors are now writing roughly seventy percent of all new mortgage originations across the country.

Denese Konowe

Seventy percent! When I started out in real estate decades ago, everyone just walked into their local branch where they had their savings account since they were ten years old. But today, if you only talk to your existing bank, you are looking at one set of rules out of a dozen possible options.

Dr Lee Konowe

Choice versus policy depth. A single institution can only offer you its own proprietary risk framework, but an independent advisor navigates lender appetites dynamically. They know who welcomes self-employed income with one year of accounts, who accepts commission structures, and who is actively hunting for debt consolidation opportunities.

Denese Konowe

And for real estate agents listening to this, this is critical. When a buyer comes to you sweating about finance, you cannot give unlicensed financial advice, obviously, but you must guide them toward exploring broad market options before they give up on a contract.

Dr Lee Konowe

Right, the first call in any property purchase strategy should be to a qualified mortgage advisor to establish true borrowing capacity across multiple credit providers, rather than relying on a single bank's automated denial.

Denese Konowe

Never let a buyer assume a bank's first answer is the final answer. Options exist if you know where to look.

Dr Lee Konowe

Spot on. Good chatting, Denese, let us get back to it.
