## FAQs
### What deposit do I need for a BTL mortgage application process consumer buy to let?
Most lenders require a **minimum 25% deposit** for consumer buy-to-let mortgages. Some may accept 20% with higher interest rates or stricter criteria.

### Can I get a BTL mortgage application process consumer buy to let through a limited company?
Consumer buy-to-let mortgages are designed for individuals, not limited companies. If you plan to operate through a company structure, you’ll need a **limited company BTL mortgage**, which is considered a professional product. These can offer tax advantages, especially post-Section 24, but come with different criteria and often higher interest rates. (Learn about limited company buy-to-let)
### What rental coverage do lenders require?
Lenders typically require a **rental income coverage ratio (ICR)** of 125%–145% of the mortgage payment, calculated using a stress-tested interest rate (usually 5.5%–6.5%). For example, if your monthly mortgage interest is £800, your expected rent must be between £1,000 and £1,160. Some lenders offer lower ICRs for higher-rate taxpayers or limited companies.
### How does Section 24 tax affect buy-to-let mortgages?

Instead, you receive a 20% tax credit on interest paid. This change can significantly reduce net profits for higher-rate taxpayers. Many landlords now consider limited company structures for tax efficiency.
