WHY COSTS ARE HIGHER

Understanding the Rate Premium on Bad Credit Mortgages

Bad credit mortgages typically carry higher interest rates than standard deals. This is not arbitrary — it reflects the additional risk a lender takes on when extending credit to someone with an imperfect credit history. The good news is that the premium varies considerably depending on the type and severity of your adverse credit, your deposit size, and how old the issues are.

The important strategic point: a higher initial rate is not permanent. Most clients with adverse credit take a two-year fixed deal, rebuild their credit record during that period, and remortgage to a significantly better rate at the end of their initial term. The goal is to get on the ladder or maintain ownership now — and refinance when your position has improved.

What Rate Should You Expect?

Missed payments only (12+ months ago), 10–15% deposit: 5.0–6.5% — minor premium above standard rates; good lender choice available. Satisfied defaults (2+ years old), 15% deposit: 5.5–7.0% — manageable premium; specialist and near-prime lenders available. Recent or unsatisfied defaults, 20% deposit: 6.5–8.5% — higher premium; specialist lenders only; deposit size critical. Satisfied CCJ (2+ years old), 15–20% deposit: 6.0–8.0% — some specialist and building society options available. IVA completed (2+ years ago), 20% deposit: 6.5–9.0% — specialist lenders only; rate improves significantly with time and deposit. Discharged bankruptcy (1–3 years ago), 25–30% deposit: 7.0–10.0% — limited lender panel; larger deposit essential; improves markedly at 3–4 years post-discharge.

A deal with a 7% rate and a £500 fee may be cheaper overall than a 6.8% rate with a £2,000 fee, depending on the loan size. Other costs to factor in: valuation fees (specialist valuations can cost more), broker fees (though at Alexander Southwell we are typically fee-free), legal fees, and early repayment charges if you need to exit the deal early.

We always compare the total cost across competing deals — not just the rate — before making a recommendation.

DEPOSIT & ITS IMPACT — How Your Deposit Changes Everything. Deposit size is arguably the single most powerful variable in a bad credit mortgage. A larger deposit reduces the loan-to-value (LTV) ratio, which in turn reduces the lender's risk — and that reduction in risk translates directly into better rates and a wider choice of lenders willing to consider your application.

WORKED EXAMPLE

A Real-World Bad Credit Mortgage Scenario

Scenario: James has a satisfied CCJ from 2022 (£800, paid in 2023). He wants to buy a property at £220,000 with a £33,000 deposit (15% LTV). Through a specialist lender, James secures a two-year fixed rate at 6.9% on a £187,000 mortgage over 25 years. His monthly repayment is approximately £1,316.

At the end of his two-year fix, James's CCJ will be four years old and satisfied. With two years of perfect payment history since his mortgage started, he remortgages to a near-prime lender at 5.1%. His monthly payment drops to approximately £1,110 — saving him over £200 a month. The key takeaway: the first mortgage is a stepping stone, not a permanent position.

As a rule of thumb: 10% gets you into the market with minor adverse credit; 15% opens specialist lender options for moderate issues; 20% is the threshold where most types of adverse credit become workable; 25–30% is where even more serious issues such as recent IVAs or early post-bankruptcy applications become possible. Every additional percentage point of deposit improves your position.

How much higher are bad credit mortgage rates? It depends on severity. Minor adverse credit (old missed payments) may add 0.5–1.5% to your rate. Serious issues like recent CCJs or IVAs can add 2–4% above standard deals.

Are arrangement fees higher on bad credit mortgages? Yes — specialist lenders often charge £1,000–£2,500. Always compare the total cost of the deal, not just the headline rate.

Can I remortgage to a better rate after a bad credit mortgage? Yes — this is part of the plan. A two-year fix gives you time to rebuild your credit, then remortgage to a more competitive rate when adverse markers are older.

Is a bad credit mortgage worth it versus renting? In most cases yes. Even at a higher initial rate, you are building equity. The plan is always to secure the mortgage now and remortgage to a better rate in 2–3 years.
