## Mortgage Overview: How BTL Mortgage Adverse Credit Works
A BTL mortgage adverse credit product is designed for landlords who have a history of credit issues but want to finance or refinance an investment property. These mortgages are available through specialist lenders who assess applications on a case-by-case basis, often using manual underwriting rather than computer algorithms.
### Key Features
– **Product types**: Fixed-rate (2, 5, or 7 years), variable, and tracker options
– **Interest-only or repayment**: Most landlords opt for interest-only to maximise cash flow
– **Available to**: First-time landlords, experienced investors, portfolio landlords, and limited companies
### Market Conditions in 2025
Rising interest rates and stricter regulations have made mainstream lenders more cautious. However, specialist lenders are stepping in to serve the adverse credit segment, provided the rental income supports the loan and the landlord demonstrates affordability.
BTL mortgage adverse credit products differ from residential mortgages in that affordability is primarily based on projected rental income, not personal earnings. However, personal income and credit history still play a role in the decision-making process.

## FAQs
### What deposit do I need for a BTL mortgage adverse credit?
Most lenders require a minimum deposit of 25%, but if you have significant adverse credit—such as recent defaults, CCJs, or missed mortgage payments—you may need to provide 30% to 40% to offset the risk. The deposit amount also depends on property type, rental income, and whether you’re applying personally or via a limited company. A larger deposit improves your loan-to-value (LTV) ratio, which can help secure better BTL mortgage rates.
### Can I get a BTL mortgage adverse credit through a limited company?
Yes, many landlords with adverse credit choose to apply through a limited company (typically an SPV). While the company is the borrower, lenders will still assess the directors’ personal credit history. Limited company buy-to-let mortgages can offer tax advantages, especially in light of Section 24 restrictions. However, rates and fees may be higher, and fewer lenders operate in this space.
