Investing in property can be a smart way to build long-term wealth, and a buy-to-let mortgage is often the first step. Unlike residential mortgages, these are designed for landlords who plan to rent out their property rather than live in it. Understanding the requirements, risks, and benefits is essential for a successful investment.
At WhichMortgage, we help investors navigate the market and find mortgages that suit their financial goals. Here’s what every potential buy-to-let investor should know in 2026.
What Is a Buy-to-Let Mortgage?
A buy-to-let mortgage is intended for properties you plan to rent out. Lenders assess your application based primarily on the expected rental income, rather than just your personal earnings.
These mortgages usually require a larger deposit, often 20–30% of the property value, and may carry slightly higher interest rates than a standard home loan, reflecting the added risk to the lender.
Who Can Get One?
Buy-to-let mortgages are generally available to:
- First-time landlords starting a rental portfolio
- Experienced investors expanding their holdings
Lenders often require a minimum income (usually around €30,000 per year) and may assess your current debts, including any existing mortgages.
How Lenders Assess Applications
Lenders typically want rental income to cover 125–145% of mortgage repayments, ensuring the property remains profitable even if interest rates rise. They also consider:
- Property type and location
- Borrower’s credit history
- Existing financial commitments
Deposits and Interest Rates
Buy-to-let mortgages usually require a deposit of 20–30%. For example, a €250,000 property might need a €50,000–€75,000 deposit.
Interest rates are generally higher than residential mortgages, with options including:
- Fixed-rate – Predictable payments for 3–10 years
- Variable-rate – Potentially lower initially but may increase
Most first-time landlords prefer fixed rates for stability.
Tax and Costs
Rental income is taxable, but certain expenses -like mortgage interest, insurance, and maintenance -can be deducted. Understanding tax obligations and keeping records is essential.
Other costs include insurance, property management fees, and potential repairs, so plan for these when calculating returns.
Risks to Consider
Buy-to-let investing carries risks:
- Periods when the property is vacant
- Unexpected maintenance or repairs
- Interest rate changes affecting repayments
- Tenant-related issues
Proper planning and professional advice help reduce these risks.
Tips for First-Time Investors
- Choose locations with strong rental demand
- Start with one property before building a portfolio
- Use a mortgage broker to find competitive deals
- Keep up with market trends and tax changes
