What buy-to-let mortgage options do Bank of Ireland offer?

We offer two buy-to-let mortgage options for your rental property:

  • You repay interest and capital throughout the term of the loan
  • You repay interest only up to 5 years

Please note:

Interest-only options revert to a standard repayment mortgage at the end of the interest-only period. Terms of up to 30 years are available for buy-to-let mortgages. Interest-only limits can vary. Eligibility criteria, terms and conditions apply.


Our mortgage guide for buy-to-let customers


  • Step 1: Estimate how much you could borrow
    Estimate how much you can borrow based on your income, expenses, and deposit. This will help you clarify the budget for your investment property.

    Remember: Buy-to-let customers can apply for a mortgage of up to 70% of the value of a property. This means you’ll need to have at least 30% of the purchase price as a deposit.

  • Step 2: Start your application
    When you’ve estimated how much you could borrow and saved your deposit, it’s time to fill in your mortgage application online, in a branch, or over the phone.

  • Step 3: Provide requested documents
    Alongside your application, you’ll need documents like:

    – Proof of identification and address – your current passport or driver’s licence and a recent utility bill
    – Proof of income – your last two payslips and a salary certificate if you’re a PAYE employee or your most recent 2 years’ audited accounts if you’re self-employed
    – Records of your finances – your last 6 months’ current account statements and 6 months’ savings account statements demonstrating regular saving (if your accounts are not with Bank of Ireland)
    – Proof of mortgage repayments – a current mortgage statement showing your last 12 repayments for any existing mortgage held with another financial institution
    – Proof of rental confirmation – written verification from a qualified estate agent or auctioneer confirming the expected rental income of the property. It may also include details about the local rental market and similar properties
    – Additional documents (if relevant) – things like separation/divorce agreement, evidence of inheritance, and statements for recently closed loans

  • Step 4. Get approval in principle (AIP)
    If your application is successful, we’ll send you a formal ‘Approval in principle’ letter. Getting AIP provides clarity on your budget.

    Remember: AIP is not a loan offer, so you cannot rely on it to enter into a contract to purchase a property. AIP generally lasts for 6 months. If it expires, you’ll need to apply for AIP again.

  • Step 5: Complete your application
    Once your application is complete, we’ll send you a formal ‘Mortgage Loan Offer’ to buy the property. It will include details of any final requirements you may need to meet before you can draw down the money to buy your new property.

    Remember: You’ll need property insurance and to have the property valued by a professional valuer that we approve of. We will send you a list of valuers at this stage. We recommend that you get a property survey carried out for your own peace of mind as this can identify potential issues that you might not otherwise see. In some cases, we may insist that you get one, particularly if the property you’re buying is older.

  • Step 6. Draw down your funds and get your keys
    If all the requirements are met, your solicitor will complete the purchase with the seller’s solicitor, and arrange to transfer the property title to you.

How much can you borrow?

Buy-to-let customers can generally borrow up to 3.5 times your gross annual income (or combined income for joint applicants) and up to 70% of the property’s value. These limits can vary depending on your circumstances, so it’s best to talk to us about your options.

Property price€250,000
Mortgage amount 70% of €250,000€175,000
Deposit required 30% of €250,000€75,000


The lender is Bank of Ireland Mortgage Bank u.c. or Bank of Ireland. Lending criteria and terms and conditions apply. A typical buy-to-let mortgage of €100,000 over 20 years with 240 monthly instalments costs €650.63 per month at 4.85% variable (Annual Percentage Rate of Charge (APRC) 5.1%). APRC includes a fee for the bank’s solicitor of €950 plus VAT at 23% plus outlay of up to €350. The total amount you pay is €157,669.65. We require property insurance. You mortgage the property to secure the loan. Maximum loan is generally 70% of the property value. A 1% interest rate rise would increase monthly repayments by €55.55 per month. The cost of your monthly repayments may increase – if you do not keep up your repayments you may lose your home. Available to over 18s only. The mortgage will be subject to assessment of suitability and affordability. APRC calculations are based on the cost per month on a €100,000 mortgage over 20 years.

Frequently asked questions


  • Are there particular insurance requirements for investment properties?
    Yes. You need to have home insurance in place before the mortgage can be drawn down. It’s also good practice to have third party liability, contents and loss of rent cover in place for investment properties.

    If your property is insured under an apartment block policy, it may only cover liability arising from accidents in common areas (like the hall, stairs and landing). It may not cover accidents that happen inside the apartment, but it’s worth checking this.

  • Is there more information available for potential investors?
    Yes, it’s worth doing some research to understand what it means to be a landlord. Things to consider include collecting rent, managing utilities like electricity, gas, water, and ongoing maintenance and repairs. You should also have a look for advice and tips on the likes of property presentation and furnishing, lease/tenancy agreements, tenant references, and Building Energy Ratings (BER).

    Some good sources of information include the Irish Property Owners Association, the Private Residential Tenancies Board, Citizens Information and Threshold – check out their websites.

    *Bank of Ireland cannot accept responsibility for information on third party websites.
