Heron Financial arranged a £238,000 mortgage with Halifax Intermediaries at an initial fixed rate of 4.89% for a solo buyer purchasing a £265,000 purpose-built flat in London. With a 10% deposit, the case sat at 90% LTV, where lender choice and affordability headroom matter more than headline rate alone.
The client
The client was a Design Manager in their late thirties to early forties, buying solo with a 10% deposit. They were targeting a purpose-built flat in London and wanted to get onto the ladder rather than hold out for a larger deposit. With a single income carrying the application, the priority was matching the case to a lender comfortable with higher-LTV solo buyers.

Why this case mattered
Higher-LTV solo cases sit in a different competitive landscape to low-LTV cases. At 90% LTV, fewer lenders compete, affordability calculations are tighter, and lender-specific rules on flats (lease length, building height, ex-local-authority flags, building safety paperwork) come into sharper focus. The headline rate at 90% LTV is also typically a step higher than the cheapest sub-60% rates, which makes affordability headroom and ongoing payment certainty more sensitive considerations than they are at lower LTVs.
For a solo buyer, every part of that is amplified. There’s only one income to do the work in the affordability calculation, and only one earner shouldering the mortgage. Heron Financial’s job in cases like this is to map the specific lender criteria that suit the borrower’s profile rather than chase the lowest headline rate.
Halifax is one of the largest mainstream lenders in the UK and has a long-standing presence in higher-LTV residential lending. For a solo buyer at 90% LTV with a clean income profile, Halifax Intermediaries was a credible match on affordability, criteria fit and pricing.
How Heron Financial approached the recommendation
The Heron adviser worked through affordability against the client’s recorded income, confirmed the deposit position against the £265,000 purchase price, and structured the mortgage around the higher-LTV approach. Rather than wait to build a larger deposit, the strategy was to get the right product placed at 90% LTV at a defensible rate. Heron Financial recommended Halifax Intermediaries and an initial fixed rate of 4.89%, locking in monthly payments through the fixed period.
The outcome
The application was submitted to Halifax Intermediaries in July 2024. The formal mortgage offer was issued in December 2024, and the purchase completed in January 2025. The client moved into their new London flat with a fixed monthly payment locked in for the fixed period, and a clear future review point with Heron Financial ahead of the product end.
What this means for buyers in a similar position
For solo buyers in London with 5% to 10% deposits, the practical question isn’t whether a mortgage is possible. It’s which lender treats the income, the property type and the LTV bracket most favourably. The difference between two lenders at 90% LTV can be the difference between a viable purchase and a stalled one. Working with a broker who reads each lender’s criteria, rather than just their headline rate, is how higher-LTV solo cases get placed cleanly.
FAQs
Can a solo buyer get a 90% LTV mortgage on a London flat?
Yes. In this Heron Financial case, a solo buyer with a 10% deposit secured a £238,000 mortgage with Halifax Intermediaries at 4.89% to purchase a £265,000 purpose-built flat in London. Lender choice is the key factor at 90% LTV, where criteria vary more than they do at lower LTVs.
Is Halifax good for higher-LTV mortgages?
Halifax is one of the largest mainstream lenders in the UK and is regularly considered for residential cases at 90% and 95% LTV. Heron Financial assesses every case on its merits and selects a lender based on affordability, product pricing, criteria fit and service standards at the time of application.
What's the smallest deposit I can buy a London flat with?
Some lenders offer 95% LTV mortgages, meaning a 5% deposit. The trade-off is a higher rate and stricter affordability. In this Heron Financial case, the client used a 10% deposit at 90% LTV, which is one of the more common entry-level positions for solo buyers in London.
How does LTV affect mortgage rates?
Higher LTV usually means a higher rate, because the loan represents more of the property’s value. The cheapest mainstream pricing typically begins at or below 60% LTV. At 90% LTV, rates step up, but a wide range of lenders still compete in that bracket.
Should I save more deposit or buy now?
here’s no universal answer. The trade-off is between a lower rate at a lower LTV (saving longer) and getting onto the property ladder sooner (paying a slightly higher rate now). Heron Financial works with each client to weigh the trade-off based on their own circumstances, rents, savings rate and the local market.
