## Mortgage Overview
A **BTL mortgage adverse credit limited company option** is a buy-to-let mortgage designed for landlords who wish to purchase or remortgage a rental property through a limited company (typically an SPV – Special Purpose Vehicle), despite having adverse credit.
These mortgages are offered by specialist lenders who understand the nuances of investment property finance. Products are available on fixed, variable, and tracker rates, with fixed terms often preferred for budgeting purposes.
This mortgage type is suitable for:
– First-time landlords with poor credit
– Experienced investors with multiple properties (portfolio landlords)
– Landlords seeking tax-efficient structures via a limited company
Unlike standard residential mortgages, affordability is based on projected **rental income**, not personal income. Lenders apply stress tests to ensure the rent covers the mortgage payments, even if interest rates rise.
In 2025, the market remains cautious but open. Lenders are more flexible with limited company structures, especially if the applicant can demonstrate strong rental yields and a clear repayment strategy.

## FAQs
### What deposit do I need for a BTL mortgage adverse credit limited company option?
Most lenders require a **minimum deposit of 25%**, but for applicants with adverse credit, the deposit may need to be higher—**up to 30% or more** depending on the severity of the credit issues. A larger deposit reduces the lender’s risk and may improve your chances of approval or access to better BTL mortgage rates.
### Can I get a BTL mortgage adverse credit limited company option through a limited company?
Yes, many specialist lenders offer buy-to-let mortgages through **limited companies**, even for applicants with adverse credit. The company must usually be an SPV (Special Purpose Vehicle) with the appropriate SIC codes. Directors will typically need to provide personal guarantees and meet other eligibility criteria.
### What rental coverage do lenders require?
Lenders usually require a **rental coverage ratio of 125% – 145%**, stress-tested at an interest rate of 5.5% – 6.5%. For limited company applications, the lower end of the ratio (125%) is often acceptable due to more favourable tax treatment. Rental income must be verified through a professional valuation.
### How does Section 24 tax affect buy-to-let mortgages?
Section 24 restricts personal landlords from deducting full mortgage interest from rental income. Instead, they receive a basic rate tax credit. This
