| Quick answer A buy to let mortgage Ireland requires at least a 30% deposit (70% LTV cap) under Central Bank rules. Lenders typically expect a rental yield of 5–6%, an interest coverage ratio (ICR) of 125–145%, and the loan must pass a stress test at 5–8%. First-time buyers generally do not qualify, and you can apply in your personal name or through an SPV — we cover both routes below. |

The four parameters that decide every Irish BTL mortgage application in 2026.
Quick answers: the six questions every Irish BTL investor asks
What is the minimum deposit for a buy to let mortgage in Ireland?
The Central Bank of Ireland caps BTL lending at 70% loan-to-value (LTV), which means you need a minimum 30% deposit. Some lenders ask for slightly more for non-standard property types or first-time landlords.
Can first-time buyers get a buy to let mortgage in Ireland?
Generally, no. Almost all Irish lenders require you to already own (or have owned) your principal private residence before approving a BTL mortgage. A small handful of specialist lenders consider exceptions, but the strong default is that first-time buyers should buy their own home first. We can map your specific options as part of a free consultation.
How much can I borrow on a buy to let mortgage Ireland?
Borrowing is driven by rental income, not personal income alone. Lenders run three checks: (1) rental yield must be at least 5–6%, (2) the rent must cover the mortgage payment by an interest coverage ratio of 125–145%, and (3) the loan must stress-test at 5–8%. Pass all three and you can borrow up to 70% of the property value.
What are the current buy to let mortgage rates in Ireland?
BTL mortgage rates in Ireland in 2026 typically sit a notch above standard residential rates because of the higher risk profile. Pricing changes regularly across lenders, we benchmark the live market for every client through our Mortgage Comparison Advice service rather than publish a snapshot that ages within weeks.
Is buy to let property still a good investment in Ireland in 2026?
Irish rental demand remains strong, particularly in Dublin, Galway, Cork and the larger commuter towns, with vacancy rates close to historic lows. That said, BTL is no longer the easy yield play it was a decade ago: higher rates, RTB regulation, increased tax compliance and a 30% deposit have raised the entry bar. For investors with the deposit and a long-term horizon, it can still produce strong total returns when held in the right structure.
What income is required for a buy to let mortgage in Ireland?
There is no specific loan-to-income (LTI) cap for BTL under Central Bank rules, affordability is driven by rental income rather than personal income. That said, individual lenders set their own minimums; Bank of Ireland, for example, will lend up to 3.5× personal income with terms up to 30 years on BTL. Most lenders also expect to see a stable personal income (often €40,000–€50,000+) and a clean credit history before approving you.
How a buy to let mortgage Ireland calculator actually works
Any honest buy to let mortgage Ireland calculator needs to run three sequential checks, the same ones an underwriter applies. We work them through below with a worked example on a €300,000 investment property:
Step 1 — Rental yield check
Divide the achievable annual rent by the purchase price. On a €300,000 property letting at €1,500 a month, that is €18,000 / €300,000 = 6.0%. Most lenders want at least 5–6%; below that, the application generally does not progress.
Step 2 — Stress-test affordability
The lender re-runs your monthly mortgage payment at a higher “stressed” rate (typically the actual rate plus around 2%, often landing at 5–8%). You must still pass affordability at the higher rate, not just the current headline rate.
Step 3 — Interest coverage ratio (ICR)
Divide the gross monthly rent by the stressed monthly mortgage payment. The result must be at least 125% (and 145% for many lenders pricing higher-rate taxpayers or SPVs). If the rent does not cover the payment by this margin, the lender cuts the loan amount until it does.
The simplest way to use these in practice is to walk through them with our Mortgage Comparison Advice team we will run the numbers for your specific target property across multiple lenders in a single call.

Personal name or SPV: two ways to hold an investment property
Personal ownership vs limited-company SPV the right structure depends on tax bracket and portfolio scale.
For a first or second property, personal ownership is usually the right answer. The setup is simpler, lender choice is wider, and the deposit and rate terms are easier to access. Rental profit is taxed at your marginal income tax rate plus USC and PRSI punishing for higher-rate taxpayers, manageable for lower-rate ones.
For higher-rate taxpayers or anyone building a portfolio of two or more properties, an SPV (Special Purpose Vehicle), a limited company incorporated specifically to hold property often makes more sense. Profits stay inside the company at a lower corporation-tax rate, can be reinvested without leakage, and the structure is friendlier to scale. The trade-off is more setup complexity, a narrower lender pool and a small rate premium. We cover the full structure decision in our dedicated SPV pillar.

Common BTL mistakes Irish investors make
- Treating BTL as passive income. RTB registration, tax filings and tenant management all take work budget for it.
- Buying the cheapest property regardless of yield. A €180,000 property at 4% yield will fail an ICR check that a €300,000 property at 6% would pass.
- Going variable just because the headline rate is lower. BTL stress-test rates are punishing, fixed rates often unlock more loan capacity.
- Ignoring the structure decision. Personal vs SPV makes a material difference once you hold two or more properties.
- No protection in place. Lenders will insist on Mortgage Protection at drawdown, arrange it early, not the week before signing.

Frequently asked questions about BTL mortgages in Ireland
1. Can I switch my current home into a buy to let mortgage if I move out?
Yes, this is called a “consent to let” arrangement or, more commonly, a switch to a formal BTL mortgage. You will need to notify your existing lender, who may require you to refinance at BTL rates with the appropriate 30% equity in the property.
2. Are buy to let mortgages available with interest-only repayments?
Some Irish lenders offer interest-only BTL options for part of the term, particularly to experienced landlords or for portfolio cases. The full term will typically include a repayment phase, and you must show a credible plan for the capital. We model both options for clients during the comparison stage.
3. Do I need to register with the RTB before drawdown?
Yes, every Irish residential tenancy must be registered with the Residential Tenancies Board (RTB) within one month of the start date. Your solicitor will typically coordinate this around closing.
4. How long does it take to arrange a BTL mortgage in Ireland?
Approval in Principle within a week is realistic with the right paperwork in place. From AIP to drawdown usually takes another 6–10 weeks, depending on the lender, the valuation and conveyancing speed.
5. Can a couple apply jointly for an Irish BTL mortgage?
Yes, joint applications are common and often help with affordability. Both applicants must usually already own (or have owned) a principal private residence.
