Is Buy-to-Let Still Worth It in Ireland in 2026?

Between high purchase prices, 52% marginal tax on rental income, tightening regulation, and a 30% deposit requirement, many potential investors ask whether BTL still makes financial sense. Here’s an honest analysis.

The Case Against BTL

• High tax burden: Rental income is taxed at your marginal rate (up to 52%), making gross yields of 5–6% into net yields of 2–3% after tax
• 30% deposit: Central Bank rules require BTL buyers to put down 30%, locking up significant capital
• Increasing regulation: RTB requirements, minimum standards, RPZ rent caps, 6-year tenancy cycles
• 1% (or 10%) stamp duty: The bulk buyer levy makes portfolio building expensive
• Negative cashflow: Many leveraged BTL properties lose money monthly (as shown in our Dublin landlord example)

The Case For BTL

• Capital appreciation: Irish property has averaged ~5% annual growth over the past decade. On a €350k property, that’s €17,500/year in equity growth
• Leverage: A 30% deposit (€105k) controls a €350k asset. If the property grows 4%/year, your return on the deposit is ~13%/year
• Mortgage paydown: Tenants pay your mortgage. After 25 years, you own the property outright
• Tax deductions: 100% mortgage interest, maintenance, insurance, BER, management fees. See our complete deductions list
• Inflation hedge: Property values and rents tend to rise with inflation

The Verdict

BTL in Ireland is a long-term wealth builder, not a cashflow play. If you’re looking for monthly income, you’ll be disappointed. If you’re looking to build equity over 10–25 years using leverage and tenant-funded mortgage payments, the maths works — especially outside Dublin where yields are higher.
