Buy-To-Let Mortgages

Introduction to Buy to Let Mortgages

A Buy to Let mortgage allows an investor to borrow money to purchase a property intended for rental purposes. The lender assesses not only the borrower’s financial standing but also the rental income potential of the property to ensure the loan is affordable.

Key differences compared to residential mortgages:

• Taking out your first Buy to Let mortgage, or
• Expanding an existing property investment portfolio

What Is a Buy to Let Mortgage?

Lenders apply different eligibility rules depending on whether you apply as an individual landlord or through a limited company (Special Purpose Vehicle - SPV).

Typical Borrower Requirements:

• Affordability is assessed on rental income, not just personal income.
• Interest rates are typically higher, and fees may be larger.
• Deposits are usually larger (commonly 20–40%).
• Many products are available on an interest-only basis, meaning landlords only pay interest each month and repay the capital when they sell or refinance.

Borrower Eligibility for Buy to Let Mortgages

Limited Company Borrowers (SPVs):

Using a limited company to hold Buy to Let properties has become increasingly popular due to tax benefits. Lenders generally require:

• Age: Most lenders require applicants to be at least 21. Maximum ages at term end often range from 70 to 85.
• Credit History: A clean credit history is preferred, though specialist lenders may accept minor issues.
• Income: Some lenders require a minimum annual income (e.g., £25,000+), though others rely solely on rental income.
• Experience: For larger loans or complex portfolios, lenders may prefer borrowers with existing landlord experience.

Deposits and Loan-to-Value (LTV) Rules

Buy to Let mortgages generally require a higher deposit compared to residential loans.

Your deposit amount can significantly impact the interest rate offered. Lower LTVs often result in more competitive deals.

• A company set up with specific SIC codes relating to property letting/management.
• Directors and shareholders to provide personal guarantees.
• Company registration with Companies House.

Rental Income and Affordability Testing

Unlike residential mortgages, Buy to Let affordability is primarily based on rental income. Lenders use a measure called Interest Coverage Ratio (ICR) to determine whether the rent is sufficient to cover the mortgage payments.

How Lenders Calculate Affordability:

• Minimum Deposit: Typically 20–25% of the property’s value.
• Common LTV Limits: Up to 75% LTV for standard BTL mortgages.
• Specialist Lending: For HMOs (Houses in Multiple Occupation) or multi-unit freehold blocks, deposits may need to be 30–40%.

Property Criteria for Buy to Let Mortgages

Limited Company Advantage:When borrowing through a limited company, lenders may apply more favourable rental stress tests compared to personal borrowers, making it easier to secure funding for higher-value properties.

Lenders also assess the property itself. Not every property qualifies for a BTL mortgage.

• Property purchase price: £250,000
• 75% LTV mortgage: £187,500 loan
• Deposit required: £62,500

Documents Required for Lender Underwriting

Typical Acceptable Properties:

Properties That May Require Specialist Lending:

• Rent must typically cover 125–145% of the monthly mortgage interest payments.
• Stress tests apply, using an assumed interest rate (e.g., 5–6%) even if your actual rate is lower.
