### Key Product Types:
– **Fixed-Rate Mortgages:** Offer payment stability for 2, 5, or 10 years
– **Variable-Rate Mortgages:** Linked to lender’s standard variable rate (SVR)

– **First-Time Landlords:** With strong credit and a solid deposit

## FAQs
### What deposit do I need for a BTL mortgage application process maisonette?
Most lenders require a minimum deposit of 25% of the property’s purchase price for a buy-to-let mortgage on a maisonette. Some may accept 20% if the property and applicant profile are strong, but this often comes with higher interest rates and stricter affordability checks. Leasehold maisonettes may also require a longer lease (typically 85+ years) to qualify for higher LTVs. A larger deposit can improve your chances of approval and secure better mortgage rates.
### Can I get a BTL mortgage application process maisonette through a limited company?
Yes, many landlords now purchase buy-to-let properties, including maisonettes, through a limited company structure. This can offer tax advantages, particularly in light of Section 24 restrictions on mortgage interest relief. Lenders will assess the company’s structure (usually an SPV), require personal guarantees from directors, and may charge slightly higher interest rates. However, the ability to offset mortgage interest as a business expense can make this route more profitable long term. (Learn about limited company buy-to-let)
### What rental coverage do lenders require?
Lenders typically require the projected rental income to cover 125%–145% of the mortgage interest, depending on your tax status and mortgage type. For basic-rate taxpayers, 125% is common, while higher-rate taxpayers or limited companies may face 145% stress tests. This is calculated using a notional interest rate, often 5.5%–7.5%, even if your actual rate is lower.
