How to Increase Your Borrowing Power Before Applying for a Home Loan

If you are planning to buy property in 2026, one of the most useful things you can do in the process is improve the way your finances look on paper. In a slower, selective market, lenders are still lending, but they are paying close attention to debt, spending habits, and overall repayment strength. That matters in Wellington in particular, where it remains a buyer’s market, stock levels are still high, and buyers generally have more time to prepare properly rather than rush into an offer.

At Capital Advice, we spend a lot of time helping clients improve borrowing power before an application goes in. It is often not about earning dramatically more. More often, it is about tightening up the areas lenders assess most closely and presenting your position clearly. 

1. Reduce or remove short-term debt

This is usually the fastest way to improve borrowing power. Personal loans, car finance, Buy Now Pay Later balances, and even unused credit card limits can reduce the amount a lender is willing to advance. Since New Zealand’s debt to income ratio rules came into effect on 1 July 2024, total debt matters even more, because banks must manage the share of lending they do above the thresholds set by the Reserve Bank.

In practice, that means paying down short term liabilities and unsecured debt before applying can make a real difference. If you have credit cards you rarely use, reducing the limits or closing them altogether can strengthen your position. This is one of the first things worth reviewing before applying for a home loan.

2. Tighten up your day-to-day spending

Banks do not just look at income. They look at how you use it. Recent statements still matter, and regular discretionary spending can work against you if it suggests your surplus cash is tighter than it needs to be.

That does not mean you need to live unrealistically for six months. It does mean cleaning up avoidable noise. Frequent overdraft use, missed payments, and heavy discretionary spending before an application can weaken affordability. In a market where buyers have a bit more room to plan, it makes sense to spend two or three months tidying this up before applying. Wellington buyers currently have that advantage, with average time to sell sitting above the 10-year benchmark, which supports a less rushed approach.

If you want a realistic sense of what repayments may look like once your budget is tightened up, our mortgage calculator is a useful starting point.

3. Build the strongest deposit you can

A stronger deposit can improve borrowing power in two ways. First, it reduces the amount you need to borrow. Second, it can improve how a lender prices and assesses the loan.

Most New Zealand home loans typically require at least a 20% deposit, although first-home buyers may have lower-deposit options depending on the lender and scenario. The Reserve Bank also eased LVR settings from 1 December 2025, increasing the share of new owner-occupier lending banks above 80% LVR from 20% to 25%. That does not mean every low-deposit borrower is automatically approved, but it does mean lenders have slightly more flexibility than previously.

If you are buying your first home, it is worth reviewing your position early through Capital Advice for your first home loan, especially if KiwiSaver will form a part of your deposit. Many first-home buyers use KiwiSaver savings toward their deposit after three years of membership.

4. Keep your income stable and easy to verify

Lenders like consistency. If you are about to apply, avoid making your income harder to assess than it needs to be. Changing roles, moving to contract work, or restructuring a business right before a mortgage application can complicate the file, even if your long-term earning potential is stronger.

That does not mean a recent job change makes finance impossible. It means clear documentation matters. The cleaner and more stable your income looks, the easier it is for a lender to assess affordability. This is particularly important under the current lending framework, where serviceability checks and DTI settings are working side by side.

5. Get the structure right before you apply

Borrowing power is not just about numbers. It is also about how the application is presented and which lender it goes to. Different banks assess the same borrower differently. One may be more conservative on living costs, another may treat variable income more favourably, and another may be stronger for low-deposit borrowers.

That is where advice matters. Capital Advice compares lenders, advises on structure, and helps clients through the full process rather than just the approval. If you already have lending in place, a mortgage review can also uncover ways to simplify debts or improve structure before you apply again, although the site’s main mortgage hub is the clearest current reference point for their broader lending support.

6. Get pre-approved early

A pre-approval gives you a real borrowing range, not a guess. In the current Wellington market, where buyers generally have more negotiating room, that can be a genuine advantage because you can act decisively without overcommitting.

If you are serious about buying, it makes sense to start with a conversation now rather than wait until you have found a property. Get in touch today and work through the practical changes that may improve your application before it reaches a lender.
