Buying With A Partner With Bad Credit in Perth, WA, Your Options Explained

You've found the right person and you're ready to buy together, but one of you has a default, a judgment, or a credit file that's seen better days. It doesn't automatically end the conversation, but it does change which lenders will look at your application, how much you can borrow, and what your deposit needs to be.

Perth's property market has moved sharply over the past year, with house medians across the inner suburbs now well above $1 million and growth corridors like Midland and Armadale still sitting within reach at $710,000 and $700,000 respectively. Whether the credit issue is a paid default, a judgment, or something more serious, the lender's assessment of your combined application turns on a few specific factors, not the imperfect history alone.

Our team helps couples and joint borrowers across Perth, WA work through exactly these situations, comparing across 60+ lenders to find the right fit. The home loan options for buyers with past credit issues side of it is where lender choice makes the biggest difference.

Can you still buy a home together if your partner has bad credit in Perth, WA?

Yes, you can, but the answer depends on what the credit issue is, how long ago it happened, and how strong the rest of the application is. A single paid default from four years ago looks very different to an undischarged bankruptcy or multiple unpaid judgments from last year. Lenders sit on a spectrum from mainstream banks that decline most adverse credit files, through to specialist and non-conforming lenders who assess the full picture and price for risk instead.

How do lenders actually read a joint application when one partner has bad credit?

Both credit files are assessed together on a joint application. That means the partner with the adverse history brings their defaults, judgments, or repayment flags into the application alongside the partner with a clean file. The clean file doesn't cancel out the bad one; it adds income, assets and serviceability, which the lender weighs against the credit risk the impaired file represents.

The factors that matter most to a lender reviewing this kind of application are the nature and age of the credit issue, the size of the default or judgment relative to the total loan, whether it's been paid or is still outstanding, and the combined income and savings position. A small paid default that's three years old sits very differently to an unpaid judgment from last year.

Under comprehensive credit reporting, lenders now see 24 months of repayment history, not just adverse listings. A pattern of on-time payments since the credit event carries genuine weight. The further in the past the issue sits and the cleaner the repayment history since, the more mainstream lenders will consider it.

What credit issues matter most to lenders on a joint application?

Not every adverse listing carries the same weight. The type, age, and resolution of the issue, combined with the overall application strength, is what lenders actually assess. Understanding where the impaired file sits on that scale tells you which part of the lender market is realistically open to you.

The common credit issues, and how they're typically read:

• › Paid default: stays on the credit file five years from the listing date regardless of payment status; paying it changes the status to "paid" but doesn't remove it or shorten the term. Some mainstream lenders will consider a single paid default if it's over two years old and below $1,000; specialist lenders are more flexible.
• › Unpaid default: harder to place with any lender until it's resolved. Most lenders require defaults to be paid or in an arrangement before they'll assess the file.
• › Court judgment: stays five years from the date of judgment and is treated more seriously than a default by most lenders. The amount and whether it's been satisfied matters significantly.
• › Part IX debt agreement: a serious credit event, staying on the file five years from completion. Most mainstream lenders won't consider an application while a debt agreement is active; specialist lenders may assess once it's completed.
• › Bankruptcy: stays on the credit file for five years from the start date or two years from discharge, whichever is later. Borrowing while undischarged isn't possible; a pathway opens after discharge through specialist lenders, typically at a larger deposit and a higher rate.

What are your options when one partner has bad credit in Perth?

There are three realistic paths for joint buyers in this situation, and which one makes sense depends on income, equity, and how serious the credit issue is. REIWA data shows house medians across affordable Perth suburbs like Midland at $710,000, Gosnells at $760,000 and Cannington at $800,000, which gives a clearer sense of which options can reach the property you're targeting.

The options worth weighing:

• › Joint application with a specialist lender: both applicants on the loan · higher rate than mainstream · typically larger deposit required · refinance to a prime lender once the file clears
• › Solo application by the clean-file partner: only one income assessed · mainstream lender access · both on the title is possible in some structures · works where one income is sufficient to service alone
• › Wait and repair: pay outstanding defaults · build repayment history · reach the five-year mark on older listings · re-apply as a joint borrower with a stronger combined file

If the clean-file partner's income is enough to service the loan alone, a solo application is often the cleaner path at the time of purchase. The partnership doesn't have to be reflected in the lending structure immediately.

What does it take to qualify when one partner has bad credit?

Eligibility on a joint application with adverse credit history is assessed differently by mainstream and specialist lenders. Mainstream lenders have credit score floors and declining policies for most default types; specialist and non-conforming lenders apply manual assessment. Either way, the application needs to satisfy standard serviceability requirements on top of the credit considerations.

What lenders typically verify on this kind of joint application:

• › Combined serviceability: both incomes assessed together against the APRA 3.0% buffer on top of the actual loan rate, plus existing commitments including credit card limits and HECS repayments.
• › Deposit: specialist lenders generally require a larger deposit than mainstream lenders for adverse credit applications; the LVR available to you narrows with the severity and recency of the credit issue.
• › Default resolution: unpaid defaults need to be addressed before most lenders will assess the file; evidence of payment or a formal arrangement is standard.
• › Repayment history since the event: 24 months of on-time repayments on any existing commitments carries genuine weight; a pattern of good conduct since the issue is the strongest rehabilitation signal available.
• › Credit enquiry management: each application leaves a mark on the credit file for five years; applying to multiple lenders in a short period compounds the problem. Compare through one broker, not by applying independently.

What government schemes can you access when buying with a partner with bad credit?

Most government schemes assess eligibility on income, purchase price and first-home-buyer status, not on credit history directly. Credit history affects which lenders will deliver those schemes, not whether you're technically eligible for them.

Schemes worth checking for joint buyers in Perth:

• › First Home Guarantee: 5% deposit, no LMI, no income cap. Perth price cap $850,000. The scheme is delivered through approved lenders, and adverse credit history may narrow which of those lenders will approve you under it.
• › WA First Home Owner Grant:$10,000 for new homes only, $800,000 cap in Perth. Eligibility rests on the property and occupancy conditions, not credit history. Available on eligible new builds regardless of which lender you use.
• › WA transfer duty concession: nil duty to $600,000, concession to $800,000 for first home buyers on new and established homes. No credit history condition applies to the concession itself.
• › Keystart Low Deposit Home Loan: 2% deposit, no LMI, income limit $228,000 for couples and families, property limit $860,000 across WA. Keystart applies its own credit assessment; a credit event doesn't automatically exclude you, but the application is assessed manually.

How does a mortgage broker help when you're buying with a partner with bad credit in Perth, WA?

The lender choice is the whole decision here. Three policy differences move the outcome for joint applications with adverse credit, and none of them are published side by side.

• › Default age thresholds: some lenders consider a single paid default over two years old on a prime application; others decline any adverse listing regardless of age. That boundary differs by lender and isn't published anywhere.
• › Manual versus automated assessment: mainstream banks typically use automated credit scoring that flags and declines adverse files early; specialist lenders apply human underwriting to the same file and reach different outcomes.
• › Refinance pathway: specialist lenders that approve adverse-credit applications today expect borrowers to refinance to a prime lender once the credit file clears; a broker who understands that pathway structures the application with the exit in mind, not just the entry.

Which of those policies applies to your exact situation depends on which lenders your broker has access to and on the specifics of the credit event, which is a conversation worth having before any application is lodged.

When does waiting make more sense than applying now?

Applying too early with an impaired credit file can make the situation harder, not easier. Each declined application leaves an enquiry on the credit file, and a cluster of enquiries in a short window signals distress to the next lender who looks. If the credit event is recent, unpaid, or significant, waiting and rebuilding is often the better financial decision even though it doesn't feel like it at the time.

Where the default or judgment is less than twelve months old, or where there are multiple listings regardless of age, the specialist lender rate premium is usually higher and the LVR available is lower, which pushes up the total cost of the purchase. Waiting another twelve to twenty-four months of clean repayment history, paying outstanding defaults, and reaching the two-year mark on an older listing can materially change both which lenders will approve the application and what rate they'll offer.

What approval challenges do joint buyers with bad credit face in Perth?

The hurdles that come up most often:

• › Enquiry accumulation: applying to multiple lenders independently leaves multiple enquiries on the impaired partner's file, which compounds the risk signal. A broker lodges one application to the most appropriate lender first.
• › Deposit shortfall on specialist products: specialist lenders typically require a larger deposit than mainstream lenders for adverse credit files; couples planning on a 5% or 10% deposit may find they need more before they can access the lenders that will approve them.
• › Misunderstanding the solo-application option: couples often assume both names must be on the loan; in many cases the clean-file partner can apply alone, buy the property jointly on title in some structures, and add the other partner to the loan once the credit issue clears.
• › Applying before defaults are resolved: an unpaid default on the file at the time of application is the single most avoidable issue; paying it doesn't remove it, but it changes how it reads to a lender and widens the pool of lenders willing to consider the file.

Frequently Asked Questions

Does a paid default disqualify us from getting a home loan together?

Not automatically. A paid default stays on the credit file for five years from the listing date, but some lenders will consider a single paid default once it's over two years old. Specialist lenders are generally more flexible than mainstream banks on this.

Can one partner apply for the loan alone so the bad credit doesn't affect the application?

Yes, where the clean-file partner's income is sufficient to service the loan alone. This is often the cleanest path for couples where one income covers the repayments, though it affects how much you can borrow overall.

Will my partner's bad credit affect whether we can access the First Home Guarantee?

The scheme's eligibility conditions focus on income, purchase price and first-home-buyer status, not credit history. Credit history affects which approved lenders will process the application, not your eligibility for the scheme itself.

How long does a default stay on the credit file?

Five years from the date it was listed, whether it's paid or unpaid. Paying it updates the status to "paid" but doesn't shorten the retention period or remove the listing early.

Is a joint application always the right structure when one of us has bad credit?

Not always. A solo application by the clean-file partner is sometimes the cleaner option, especially where one income services the loan comfortably. A broker can model both structures before any application is lodged, which is worth doing first.

Is a mortgage broker better than going to the bank when one of us has bad credit?

A mortgage broker, every time in this situation. Banks are one lender and most mainstream banks will decline an application with adverse credit on the file. A broker compares across mainstream and specialist lenders and identifies which ones will look at your combined application before any enquiry is lodged.
