Do I need a guarantor? (Part 1)
What is a guarantor mortgage? What is a parent guarantor?
A guarantor mortgage is a type of loan where someone else, often a family member, agrees to take on financial responsibility if you’re unable to keep up with your own repayments. Basically, it’s a mortgage that’s supported by somebody else – the guarantor.
If things unfortunately went wrong, the guarantor would be equally liable for the mortgage. This setup is often used when the borrower may have slightly lower income than they need for the mortgage they want; or a small deposit or limited credit history makes it difficult to get approval for a loan on their own. The guarantor is then brought in as support.
A parent guarantor is one of the most common types. In this case, a parent agrees to support the mortgagee – their child. That gives the lender more confidence that the loan will be repaid if the borrower runs into trouble.
Do mortgage lenders still accept guarantors? Is it easier to get a mortgage if you have a guarantor?
Many lenders do still offer guarantor mortgages. They’re probably not as common as they were. Several building societies, high street banks and niche lenders continue to accept them.
Having a guarantor can definitely improve your chances of getting approved, especially if you have a smaller deposit, a modest income or a less than perfect credit score.
The guarantor’s financial backing reduces the lender’s risk, and may even allow you to borrow more or access better terms.
How does a guarantor mortgage work?
A guarantor mortgage follows a simple structure that comes with serious responsibilities for the guarantor themselves.
The first step is establishing that the person wanting a mortgage needs support. You might not meet the lender’s criteria on your own, maybe due to income levels, credit history or deposit size. So you need support.
Step two is to find a guarantor to get involved. Usually this is a parent or a very close relative. The guarantor agrees to cover the mortgage if the mortgagee is unable to. They’re responsible financially if things go wrong.
Step three is for the guarantor to offer security – in the form of their own property, collateral, or savings. Some form of security offer is made.
Step four is to confirm that the guarantor doesn’t co-own the property, but they would be legally liable for missed payments.
In step five, the lender completes financial checks. Lenders assess both you as the mortgagee and the guarantor, looking at your finances including income, debt and credit history.
Step six is access to better mortgage terms. With a guarantor you may be able to qualify for a larger mortgage, a lower deposit requirement, or possibly even improved interest rates.
Then, step seven is confirming the risks for the guarantor. If the mortgage defaults, your guarantor may need to step in. That could potentially put their savings or home at risk if payments were continually missed.
The last step, step eight, is an exit strategy. Provided everything is going well and payments are being made to the lender, you’ll be thinking about getting the guarantor out of the deal. Generally, once you’ve paid off a certain proportion of the mortgage and built up equity, the lender may release the guarantor from the agreement. Obviously, that’s a really positive position to be in.
Will I be able to borrow more with a guarantor mortgage? How much of a mortgage can I get with a guarantor?
Yes, a guarantor can help you borrow more than you might be able to qualify for on your own. They do that by providing additional financial security so that lenders feel more comfortable offering a higher loan amount.
How much you can actually borrow depends on both your financial situation and that of your guarantor. In some cases, you may be able to borrow more, sometimes up to 100% of the property value, particularly if the guarantor’s assets are used as security.
So there’s no fixed amount that you can borrow. It’s down to individual circumstances, but with the support of a guarantor, you could potentially buy with less deposit and borrow more money.
Can I get a 100% mortgage with a guarantor?
Potentially, yes. Some guarantor mortgages allow you to borrow the full purchase price of a home without needing a deposit. This does usually require strong financial backing from the guarantor, through either their savings or property equity.
It’s a very individual assessment. If you’re looking at this route, speaking with a broker like myself will really help to assess whether that’s feasible. It’s also subject to what products are around at any point in time.
Do guarantor mortgages have higher interest rates?
Yes, generally guarantor mortgages will come with higher interest rates compared to standard loans. That’s because they do carry more risk for the lender.
There’s also less competition in this part of the market, which means those lenders will potentially charge a little more for the facility. Rates can be also influenced by the size of the loan secured by the guarantor, especially if it’s a high Loan to Value.
Who is a guarantor mortgage suitable for? How do you qualify for one?
A guarantor mortgage can be a helpful option for many different types of buyers. The most common is probably First Time Buyers, but it could equally suit borrowers with low or unpredictable incomes, those with a limited or poor credit history, or applicants with a small or zero deposit.
To qualify, the borrower must show they can afford the repayments with the guarantor’s backing. It’s about proving you can afford the mortgage, not just in your own view but from the lender’s perspective.
The guarantor must be a UK resident and currently over the age of 21. Generally, they will need to be under 75 at the end of the mortgage term. The lenders like guarantors to have a strong credit history and show stable income and or savings, and often, lenders expect the guarantor to have their own home or significant equity within a property.
What documents should I provide for a guarantor mortgage? Any differences here?
Not really. It’s the standard documentation that lenders generally require. Typically that means proof of identity and evidence of income via pay slips, tax returns, bank statements and/or proof of savings. They also request details of any existing debts or financial commitments.
If property is being used as security, we need the property details and proof of the equity. Both the applicant and the guarantor also undergo a full credit check as part of the lender’s affordability assessment. It’s very similar to applying for a standard mortgage.
Who can guarantee a mortgage?
Typically a guarantor needs to be a UK resident, over 21, under 75 at the end of the mortgage, and able to show sufficient income or assets to cover the loan if needed. They also need to be financially secure with good credit.
Generally, guarantors are parents or close family members. Some lenders may consider relatives or trusted friends, but that’s less common.
What are the risks of a guarantor mortgage?
Being a guarantor is a serious legal and financial commitment. As we’ve highlighted, if the borrower can’t repay the loan, the guarantor is definitely on the hook. They may be asked to cover missed payments, or even indeed repay the loan in full. There is the risk of potentially losing their own assets, like savings or property, if that’s used as security.
Another potential downside is an impact on the guarantor’s own ability to borrow. There could be damage to the guarantor’s credit score if the borrower defaults. There would also be legal complications and stress if things go wrong.
These risks can appear very negative, but when you’re acting as a guarantor for somebody else, it’s helping somebody achieve something they couldn’t on their own. Lenders usually request that guarantors undertake independent legal advice to make sure they’re aware of the potential risks.
How can a broker help with guarantor mortgages?
I would always advocate speaking with a broker if you need assistance. With more individual circumstances like guarantor mortgages, we’re very used to speaking to people and finding solutions. Speak to a professional broker and we’ll help identify the right approach for you.

Do I need a guarantor? (Part 2)
Sam Hubbard continues the conversation on guarantor mortgages, in our second episode of two, recorded in August 2025.
How much does a guarantor need to earn for a mortgage?
There’s no set amount that a guarantor must earn. It very much varies from lender to lender and individual situations.
The key is that the lender needs to be confident that the guarantor has the income to comfortably cover the mortgage payments if the borrower defaults.
They do a full affordability assessment on the guarantor, looking at income, outgoings and existing debts. It’s not about how much they earn, it’s about whether they’re credit worthy and there’s adequate security to support the mortgage application.
The guarantor’s income doesn’t have to be from employment. It can be from other sources such as pensions, investments or other verifiable means.
What happens if my guarantor is unable to make repayments too?
As a mortgage applicant, if you bought your property supported by a guarantor, you’re both liable for those mortgage payments. The worst case scenario highlights the significant risk involved for a guarantor.
If both the mortgage holder and guarantor are unable to make the mortgage repayments, the lender will eventually take legal action to recover the debt – which could ultimately lead to a repossession of the property.
If the sale of that home doesn’t cover the full amount of the outstanding mortgage, the lender could actually pursue the guarantee for the shortfall. As we’ve highlighted in previous podcasts, being a guarantor is a serious matter. It shouldn’t be taken lightly, and independent legal advice is always recommended.
Can I get a guarantor mortgage for a Buy to Let property?
It’s really rare. I don’t think I’ve ever come across it. Some specialist lenders do offer guarantor mortgages for Buy to Let properties, but there’s a key reason why Buy to Lets don’t generally have guarantors.
It’s because the rental income will generally be what supports the mortgage. So if you’re calling a guarantor in, it probably means that the rent is not sufficient. Therefore, the yield you’re going to get from the property is probably fairly slim.
There would have to be a very good reason for someone to consider a guarantor on that route.
Can a parent be a guarantor if they are retired?
Yes, a retired parent can be a guarantor, providing they meet the individual lender’s criteria. Certain lenders will assess income from pensions, savings and investments, and possibly other sources. There’s no reason why a retired parent couldn’t be a guarantor.
What happens if my guarantor dies?
The death of a guarantor does not automatically terminate the guarantee. The liability for the debt will often pass potentially onto the guarantor’s estate, although the specific terms about what happens will depend on the mortgage agreement.
The lender may require you to find a new guarantor, or may review your financial situation to see if you could afford the mortgage on your own.
This is an often overlooked aspect of financial planning and mortgages, where simple things like life assurance and placing that in trust can make a big difference. Having life cover in place for the guarantor would mean that in the event of death, the mortgage could be repaid, therefore getting rid of the liability.
Do guarantors get credit checked?
Yes, absolutely. A lender will definitely perform a credit check on guarantors as part of the application process. It’s a crucial step for the lender to assess the guarantor’s financial history, standing and reliability.
Usually this will be a soft credit search which won’t affect the guarantor’s credit score. However, if approved and the mortgage starts, they may carry out a full hard credit search.
Can I stop being a mortgage guarantor?
Yes, it is possible to be released from being a guarantor and the obligations of that, but it’s not a simple process. The first step would be for the lender to assess the original mortgagee’s financial standing. If that had improved and they could take on the loan on their own, possibly the guarantor can be removed.
Can I get a guarantor mortgage with bad credit?
Getting a guarantor mortgage with bad credit is possible, but it will definitely be more challenging.
While we assume the guarantor has a good credit history, which provides a safety net for the lender, they would still want to assess the individual main applicant’s credit file. It will just depend on how severe that is.
Again, this is where brokers come in. We’d look at the credit file and talk to lenders to see which would be suitable and likely to accept a case in this situation.
How do I get a guarantor mortgage? What is the process?
The best way to get a guarantor mortgage is to work with a broker who specialises in this type of product.
We have access to a wider range of lenders, including those not available on the high street. We help you and your potential guarantor gather all the necessary financial documents.
Because you’re looking at a very specialist area of the market, it needs specialist advice.
