5% deposit mortgages are making a comeback… but here’s the catch
At Pia Financial Solutions, we know why the return of more 5% deposit mortgages is getting attention. In 2026, low-deposit mortgage choice is stronger again, with hundreds of 95% loan-to-value products available across first-time buyer and moving-home searches. The government’s Mortgage Guarantee Scheme has also been permanent since July 2025, helping support the availability of 91% to 95% loan-to-value lending across the UK.
On the surface, that is good news. For buyers trying to get onto the property ladder with smaller savings, a 5% deposit can make homeownership feel more achievable. But a smaller deposit is only one part of the picture, and wider product availability does not automatically mean wider access for every buyer.

The direct answer
Yes, more 5% deposit mortgages are back in the market. But the catch is simple: having a 5% deposit does not guarantee that a lender will offer you a mortgage. Deposit size helps, but affordability will still carry the most weight. Lenders continue to assess income, outgoings, employment security, credit history and whether repayments would still be manageable if rates rise. For loans under the Mortgage Guarantee Scheme, lenders must also verify income, carry out an affordability assessment and stress test, and make sure the borrower is not credit-impaired.
To explore what a 5% deposit could mean in practice, buyers can use our Find an Adviser search to connect with a local mortgage adviser and look at the wider picture, not just the deposit headline. Pia’s adviser directory is built around postcode search and mortgage support remains one of our core service areas.
Why this matters
For many buyers, the deposit is the most obvious hurdle because it is the part you physically have to save. But lenders do not base decisions on deposit size alone. They look at income, regular spending, debt commitments and the overall strength of the application. A 5% deposit may get you into the conversation, but monthly affordability is usually what shapes how much you may be able to borrow and whether a particular deal is realistic.
That is why two buyers with the same 5% deposit can end up with very different options. One may fit the lender’s affordability model comfortably, while the other may find that income, credit profile, existing commitments or property type limit what is actually available. That difference is where advice and planning become especially important.
What has changed in 2026?
The biggest shift is that support for low-deposit lending is now more established. The Mortgage Guarantee Scheme became permanent from July 2025, with the aim of sustaining the availability of 91% to 95% loan-to-value mortgages for eligible first-time buyers and home movers purchasing their main home. At the same time, product choice has improved, which is one reason more buyers are seeing 5% deposit options appear in searches again.
Even so, 95% loan-to-value deals still make up a relatively small share of the wider residential mortgage market. So while the return of 5% deposit products is positive, it does not mean every lender is offering the same options or that every buyer will fit the same criteria.
Key concepts to understand
What is a 5% deposit mortgage?
A 5% deposit mortgage is usually a 95% loan-to-value mortgage. In simple terms, you put down 5% of the property price and borrow the remaining 95%. On a £250,000 purchase, that would mean a £12,500 deposit and a £237,500 mortgage. Loan-to-value simply compares the amount you borrow with the value of the property.
What does the Mortgage Guarantee Scheme do?
The scheme is designed to support the availability of low-deposit mortgages by giving participating lenders a government-backed guarantee on part of the risk. That support helps lenders keep 91% to 95% loan-to-value products in the market for eligible buyers.
What does it not do?
It does not guarantee that a buyer will be accepted for a mortgage. Full lender checks still apply, including affordability, income verification, credit checks and stress testing against future interest rate rises.
The catch: what really decides whether a 5% deposit deal is open to you
1. Affordability still comes first
At Pia, this is the main point we would want buyers to understand. A smaller deposit can help open the door, but the lender still needs to be comfortable with the monthly repayment. That means looking at income, committed spending, essential household costs and whether the mortgage still looks sustainable over time.
2. Income still affects how much you may be able to borrow
Lenders typically use a loan-to-income approach when deciding the upper end of borrowing. A common guide is up to around four and a half times annual income, although many applicants are offered less. That means some buyers can save the 5% deposit but still find that their target property is outside what they can borrow comfortably.
3. Credit history still matters
Low-deposit lending does not remove the importance of a clean and stable credit profile. Once a formal application is made, lenders carry out a credit check, and for Mortgage Guarantee Scheme eligibility they must be satisfied that the borrower is not credit-impaired. Under the published scheme rules, recent serious arrears, some county court judgments, or a recent IVA or bankruptcy can affect eligibility.
4. Property and product rules still apply
Not every 5% deposit mortgage works for every situation. The scheme is aimed at first-time buyers and home movers buying their main home on a capital repayment basis. It is not available on shared ownership properties, second or additional homes, commercial or buy-to-let property, or interest-only, offset and guarantor mortgage loans. On top of that, lender criteria can still vary from one provider to another.
5. Higher loan-to-value can mean higher overall cost
A smaller deposit can help someone buy sooner, but it often comes with a higher rate than a larger deposit would. That can mean higher monthly repayments and more interest paid over time. So while 5% deposit mortgages can be useful, they should still be judged on affordability and long-term comfort, not just on minimum entry point.
6. The risk buffer is smaller
With only 5% equity in the property at the start, there is less room for house price falls. That means the risk of negative equity can be higher than it would be with a larger deposit. It does not make a 5% deposit mortgage the wrong choice, but it does mean buyers should look at the bigger picture before focusing only on getting through the door.
This is exactly why we do not look at deposit size in isolation. Buyers who want to understand how deposit, income, affordability and credit history fit together can start by using our Find an Adviser tool and speaking to someone local about the full picture.
FAQs
Are 5% deposit mortgages really back?
Yes. Product choice is stronger again in 2026, with hundreds of 95% loan-to-value products listed across first-time buyer and moving-home searches, and the Mortgage Guarantee Scheme has been permanent since July 2025.
Does a 5% deposit guarantee I can get a mortgage?
No. Lenders still have to assess affordability, verify income, stress test the mortgage and review credit history before deciding whether to lend.
Are 5% deposit mortgages only for first-time buyers?
No. The current Mortgage Guarantee Scheme applies to eligible first-time buyers and home movers buying their main home on a capital repayment basis.
Can a smaller deposit mean higher monthly payments?
Yes. A higher loan-to-value often means a higher rate than a larger deposit would, which can increase monthly repayments and the total cost over time.
Can I use a 5% deposit mortgage on any property?
No. Scheme-backed lending is not available for every scenario, including shared ownership, second homes, buy-to-let, interest-only, offset and guarantor mortgages, and lenders can also apply their own additional criteria.
What matters most: deposit or affordability?
Both matter, but affordability is usually the bigger factor in what a lender may actually offer. A 5% deposit can help you access the market, but income, outgoings and credit profile still do most of the decision-making work.
Conclusion
More 5% deposit mortgage deals returning to the market is a positive step. It gives buyers with smaller savings more routes to explore and makes low-deposit borrowing easier to find than it was during tighter periods. But the catch remains the same: deposit size is only one part of the mortgage conversation. Affordability, income, credit history and lender criteria still shape what may actually be possible.
At Pia Financial Solutions, we believe the most useful approach is to look at the whole picture early. Buyers can use our Find an Adviser search to speak to a local adviser and understand how a 5% deposit fits into their wider mortgage options.
