First time buyers are being warned not to leap into signing up for 100% mortgages.
Pepper Money, a specialist lender, says the concept of a 0% deposit and a 100% mortgage sound tempting to first time buyers in particular.
But there are risks.
A statement from the lender cautions: “These products are by no means an easy route to homeownership.
“While they provide immediate access, there are significant risks compared to traditional mortgages with a 10% to 25% deposit.”
When comparing 0% deposit mortgages with more traditional options, the difference isn’t just the deposit required – it’s the interest rates and fixed-term options borrowers are offered.
According to independent mortgage market monitor Moneyfacts, two-year fixed rates for higher-LTV mortgages (95%) average around 5.3%, compared with 4.3% for borrowers with a 40% deposit.
Five-year fixed rates show a similar gap: 5.7% for 95% LTV versus 4.6% for 40% LTV.
Higher-LTV deals often push borrowers into longer fixed terms at higher rates, limiting flexibility and increasing long-term costs.
Borrowers with larger deposits can access more competitive two- or five-year fixes at lower rates, potentially saving thousands of pounds in interest over the life of the mortgage.
Pepper highlights five particular issues with 0% deposit, 100% mortgages:
1. Higher costs: 100% mortgages carry higher interest rates than loans backed by a deposit. Even a small deposit can significantly reduce your monthly repayments and total interest paid over the life of the loan;
2. Negative equity risk: If property values fall, borrowers without a deposit have no financial buffer. This risk is minimal with a 10–25% deposit, which acts as a protective cushion.
3. Higher loan-to-value ratios: A 0% deposit mortgage typically means higher monthly repayments and less flexibility if personal circumstances change.
4. Long-term affordability: Borrowers taking out no-deposit mortgages may find themselves stretched financially in the early years. Without equity built up, they have limited options to refinance or remortgage.
5. Limited mortgage options: Some lenders restrict access to certain products if no deposit is available, meaning borrowers may face fewer options and potentially less competitive terms.
