Shared ownership mortgages with bad credit (first-time buyers)

Shared ownership can be a practical way to buy your first home when you can’t afford to purchase outright. Instead of buying the whole property, you buy a share and pay rent on the remaining portion.

If you have bad credit, the process can feel more complicated. Some lenders may be cautious, but shared ownership is designed to help eligible first-time buyers, and there may be lenders willing to consider applications where you can show affordability and a sensible plan for the future.

This guide explains how shared ownership mortgages work, how adverse credit is typically assessed, and what you can do to improve your chances.

Shared ownership mortgages with bad credit for first-time buyers

What are shared ownership mortgages?

Shared ownership is a part-buy/part-rent arrangement.

You usually:

Buy a percentage of the property (the share you own)
Take out a mortgage on that share
Pay rent on the share you don’t own
Pay leasehold-related costs (where applicable), such as service charges and ground rent

Over time, you may be able to buy additional shares, often called staircasing, until you own the property outright.

Staircasing typically involves agreeing to purchase more shares and paying the price based on the property’s valuation at that time. Because valuations can change, it’s important to think about how you would manage future mortgage repayments and any additional costs if you plan to increase your share.

For more detail, read our Shared Ownership staircasing guide. If you are considering a change of mortgage later, our bad credit remortgages guide and guide to comparing remortgage rates explain what to consider.

Why bad credit can affect shared ownership mortgage applications

A shared ownership mortgage is still a mortgage application. Lenders will assess your overall financial position, including how you’ve managed credit in the past.

With bad credit, you may face extra scrutiny because lenders may view you as higher risk. Common factors that can influence decisions include:

Missed or late payments
Defaults
CCJs
IVA / debt relief arrangements
Bankruptcy (and the time since discharge)
A broader pattern of financial difficulty

It’s important to note that shared ownership doesn’t automatically “cancel out” the impact of adverse credit. What it can do is provide a route where the mortgage size and structure of costs may be different from buying outright, so the overall affordability picture matters.

How lenders typically assess affordability with adverse credit

Each lender has its own approach, but most will focus on whether you can meet the ongoing costs sustainably.

For shared ownership, that usually means looking at whether you can afford:

Mortgage repayments on the share you’re buying
Rent on the remaining share
Leasehold costs (where applicable)
Other monthly commitments (for example, credit cards, loans, childcare, utilities)

Where you have adverse credit, lenders may also consider whether you’ve shown improved behaviour going forward. That often involves looking at:

Current income stability
Your budget and spending patterns
The deposit you can contribute
The type of credit issue and how long ago it happened
Whether the issue has been resolved and what you’ve done since

Deposit and mortgage size: why shared ownership can help

Shared ownership can reduce the amount you need to borrow because you’re only financing a portion of the property. That can mean a smaller mortgage than if you bought the home outright and potentially more manageable monthly mortgage repayments.

However, you’ll still pay rent on the portion you don’t own, plus leasehold costs. So lenders will generally assess your total monthly housing cost, not just the mortgage payment. For more on how a deposit affects borrowing, see our loan-to-value guide.

What credit issues can matter most

Bad credit isn’t one single thing. Lenders will usually look at the nature, severity, and timing of the issue.

Late payments

Late payments can be viewed differently depending on frequency and recency. A small number of late payments from some time ago may be treated more leniently than repeated late payments over a recent period.

Defaults

Defaults usually carry more weight because they indicate a bill was not paid as agreed. Lenders may consider how many defaults you have, the amounts involved, and whether they’ve been settled.

CCJs

CCJs can affect mortgage decisions, particularly if they are recent or relate to significant amounts. Some lenders may be more cautious where CCJs are still within a shorter timeframe. Read our first-time buyer guide to mortgages with a CCJ for more detail.

IVA / debt relief arrangements

If you are currently in an IVA or similar arrangement, many lenders may be reluctant to proceed. Where an IVA has been completed, decisions may depend on how long ago it ended and how your finances have looked since.

Bankruptcy

Bankruptcy can make it harder to obtain a mortgage, especially while it is still recent on your credit file. Some lenders may consider applications after a period has passed, but the overall affordability and financial stability still matter.

Debt management plans (DMPs)

If you’re paying debts through a DMP, lenders may look at whether payments are being maintained and whether your overall commitments are manageable. See our DMP mortgages guide for first-time buyers.

Shared ownership and leasehold costs: don’t overlook the extras

Shared ownership is often structured as leasehold, which means your monthly costs may include more than just mortgage and rent.

Depending on the property and scheme, you may need to budget for:

Service charges for communal areas
Ground rent (where applicable)
Ongoing maintenance and compliance costs under the lease

These costs can be especially important if you’re already managing adverse credit, because lenders will want to see that your budget can handle the full picture.

How the shared ownership application process usually works

Shared ownership involves both the property provider (often a housing association) and the mortgage lender.

A typical flow is:

Confirm you meet the shared ownership criteria for the scheme and property
Apply to buy a share through the housing association/provider
Submit a mortgage application for the share you’re purchasing
Provide documentation supporting your income, affordability, and credit history
Complete the purchase and begin paying mortgage + rent

Because shared ownership has two moving parts, it’s helpful to ensure your finances are aligned with both the purchase requirements and the mortgage lender’s assessment.

How to strengthen your application with bad credit

While there’s no guaranteed outcome, preparation can make a meaningful difference, particularly with specialist lenders.

1) Check your credit file for accuracy

Credit file errors happen. If you find inaccuracies, correcting them can prevent unnecessary negative impact.

2) Make your affordability case clear

A strong application usually shows that your income supports your commitments. Prepare a realistic monthly budget that includes mortgage repayments, rent, leasehold costs and other existing commitments.

3) Reduce outstanding debt where possible

Lower balances and healthier credit usage can support the overall assessment.

4) Demonstrate stability going forward

Even if past issues remain visible, consistent on-time payments and stable income can help show you’re managing your finances responsibly.

5) Be upfront about past credit issues

Lenders may want context. Explaining what happened and what you’ve done since can help the application make sense.

Joint options and guarantors

Some first-time buyers find that their credit history limits lender options. In those situations, joint arrangements may be considered depending on the circumstances.

Two common structures you may hear about include:

Joint mortgages, where both applicants are responsible for repayments
Joint borrower sole proprietor (JBSP) arrangements, where one party may have sole ownership while both parties are involved in the mortgage commitment

These options can sometimes help where one applicant has a stronger credit profile or more suitable affordability. The key point is that lenders will still assess both applicants’ financial positions.

A guarantor is sometimes discussed for borrowers with complex circumstances. In general terms, a guarantor can provide additional security for the lender.

However, guarantors do not automatically override credit concerns. If the credit issue is outside a lender’s acceptable criteria, adding a guarantor may not change the outcome.

For more detail on joint borrowing, see our joint borrower sole proprietor guide.

Common reasons shared ownership applications are declined

While each case is different, declines often relate to:

Insufficient deposit or an LTV that doesn’t meet lender expectations
Affordability concerns when rent and other commitments are included
Recent or unresolved credit issues
Unstable income or affordability that doesn’t leave enough headroom
Credit file information that creates uncertainty about financial management

Specialist lenders and why they can be relevant

Some mainstream lenders may not offer mortgages where credit history is weak. Specialist lenders may be more experienced in assessing borrowers with adverse credit.

This doesn’t mean every application will be accepted, but it can mean there are more options where you can show:

Clear affordability
A deposit that fits the lender’s risk approach
Evidence of improved financial management
A credible explanation of past issues (where relevant)
