Frequently asked questions
What is a 98% LTV mortgage?
Loan-to-value (LTV) is the loan as a percentage of the property price. A 98% LTV mortgage means the lender covers 98% of the price and you provide just 2% as a deposit — a new low-deposit option launched by some UK lenders in 2026, aimed at first-time buyers struggling to save a traditional deposit.
Is a 2% deposit mortgage available to everyone?
No — these deals typically have a minimum deposit amount in pounds (e.g. £5,000-£10,000, meaning the 2% rate only applies above a certain property price), a maximum loan size (often around £500,000), a minimum income requirement, and may exclude self-employed applicants or certain regions. Check the specific lender's criteria.
Why is the interest rate higher on a low-deposit mortgage?
Lenders take on more risk with a smaller deposit cushion, so low-deposit / high-LTV deals almost always carry a higher interest rate than mortgages with 10-25% down. Over the life of the loan this can add up to significantly more interest than saving a bigger deposit first — this calculator lets you compare both scenarios.
Should I use a 2% deposit even if I could save more?
It depends on your situation — a smaller deposit gets you on the property ladder sooner (useful if prices/rents are rising faster than you can save), but means a bigger loan, higher rate, and less equity cushion if prices fall. Run the numbers both ways and weigh getting in sooner against the higher lifetime cost.
