2% Deposit Mortgages Have Arrived — Are They Actually a Good Deal?

Two lenders have now launched mortgages requiring a deposit of just 2% of a property's value, aimed squarely at first-time buyers priced out by rising deposit requirements. It's the most aggressive low-deposit push the market has seen in years — but the small print matters more than the headline number.

What's actually on offer

Santander's "My First Mortgage" offers a fixed rate of 5.19% over five years with no product fee, at up to 98% loan-to-value. But there's a catch: the deal mandates a minimum £10,000 deposit, so a genuine 2% contribution only works on homes worth £500,000 or more — hardly typical first-time-buyer territory in most of the UK. Lending above 95% LTV is also restricted to existing houses, ruling out new-build flats.

Leeds Building Society's "Start Mortgage" is more accessible: a minimum deposit of £5,000, meaning the 2% figure applies to homes worth £250,000 and up — much closer to real first-time-buyer prices in many regions. It's a five-year fixed rate of 5.65%, with a free standard valuation and no completion fee. Borrowers can access loans of up to five times income, self-employed applicants are accepted, and gifted deposits are allowed.

The trade-off: rate and risk

Both deals carry rates noticeably above the best available at higher deposit levels — where Nationwide currently leads the 60% LTV two-year market at 4.24%, according to Mortgage Introducer's weekly tracker. That gap of roughly 1.4 percentage points reflects the extra risk lenders take on at 98% LTV: borrowers start with almost no equity, so a small fall in house prices could tip them into negative equity.

Should you use one?

A 2% deposit mortgage can get you on the ladder years earlier than saving for a traditional 10% or 15% deposit — but weigh it against the numbers first, as themortgagebroker.co.uk and other brokers note. Before committing:

• Calculate the total monthly cost at the higher rate over five years, not just against your current rent.
• Check what happens at the end of the fixed term — if rates haven't fallen and your equity hasn't grown much, you could face a rate shock on remortgaging.
• Confirm the property type and price band both fit the lender's minimum deposit rules — the "2%" figure is often only accurate above a certain house price.
• Compare against saving a larger deposit for another 12–18 months, factoring in current mortgage rate trends, which have been gently falling through 2026.
• Get independent advice from a whole-of-market mortgage broker before applying — low-deposit products vary significantly between lenders.

How it compares internationally

Low-deposit lending isn't unique to the UK. In the United States, FHA-backed loans allow deposits as low as 3.5% for qualifying buyers, while Canada's insured mortgage scheme permits down payments from 5% on homes under CAD $500,000, according to the Canada Mortgage and Housing Corporation. Australia's government-backed Home Guarantee Scheme similarly lets eligible first-time buyers purchase with as little as 5% down.
