Northern Ireland buy-to-let properties regularly deliver gross yields of 6–9% — significantly above the UK average. But gross yield is only part of the picture. This guide sets out realistic return expectations across all metrics: gross yield, net yield, cash-on-cash return and total return including capital growth.

Gross rental yield in Northern Ireland — current benchmarks

Gross yield varies significantly by area, property type and purchase price. Current benchmarks for well-sourced Northern Ireland buy-to-let properties:

• Belfast (east and north) — 7–9% gross yield on 2–3 bed terraces
• Belfast (south) — 5–7% gross yield; lower yield, stronger capital growth profile
• Lisburn — 6–8% gross yield; strong professional tenant demand
• Londonderry/Derry — 7–9% gross yield; lower entry prices, strong student and professional demand
• Newtownabbey / Bangor — 6–8% gross yield; family tenant profile

For a rough calculation method: Annual rent ÷ Purchase price × 100 = Gross yield %. A property purchased for £120,000 renting at £800/month (£9,600/year) = 8% gross yield. See the full calculation guide: How to calculate ROI like a professional investor.

Net rental yield — what you actually keep

Net yield accounts for all running costs. On a typical Northern Ireland buy-to-let, expect to deduct:

• Letting agent management fees: 10–12% of rent
• Landlord insurance: £150–£400/year
• Maintenance budget: approximately 1% of property value/year
• Void periods: 2–4 weeks/year as a planning assumption
• Compliance certificates: £150–£300/year amortised

After these deductions, a property with 8% gross yield typically delivers 5–6% net yield. Still strong compared to most UK markets and virtually all other asset classes at equivalent risk.

Cash-on-cash return on a leveraged purchase

For investors using a buy-to-let mortgage, cash-on-cash return is the most meaningful metric — it measures return on the actual cash you deploy.

Example: £120,000 property, 25% deposit (£30,000) + costs (£8,000) = £38,000 total cash invested. Monthly rent £800, mortgage payment (interest-only, 5%, £90,000) = £375. Net monthly income after all costs: approximately £200–£250. Annual net income: £2,400–£3,000. Cash-on-cash return: 6.3–7.9%.

On a higher-yield property or one purchased below market value with refurbishment, cash-on-cash returns of 12–16% are achievable. Related: The hidden costs investors forget to budget for.

Capital growth — what the data shows

Northern Ireland house prices have risen consistently over the past decade. While growth rates vary by area and period, average annual capital appreciation of 3–5% is a reasonable planning assumption for well-located residential property. South Belfast has outperformed significantly, while some peripheral areas have lagged.

Capital growth compounds over time. A property purchased for £120,000 appreciating at 4% annually is worth approximately £178,000 after 10 years — a £58,000 gain in addition to a decade of rental income.

Total return — putting it all together

A well-purchased, well-managed Northern Ireland buy-to-let investment typically delivers:

• Net rental yield of 5–6% annually
• Capital growth of 3–5% annually
• Total annual return: 8–11%

With leverage, total returns on cash deployed are considerably higher. This compares favourably to equities on a risk-adjusted basis, with the added benefit of a tangible, insured, income-generating asset.
