Rental yield is the foundational metric of every property investment decision — yet most investors compare properties using gross yield while the real number that matters is net yield after tax and costs. Across five major markets in 2026, the difference between gross and net can be as large as 5 percentage points — turning an apparently attractive investment into a mediocre one, or revealing hidden value in a market that looks expensive on a gross basis.
Gross Yield vs Net Yield: The Critical Distinction
Gross yield = (Annual rent ÷ Property price) × 100
Net yield = ((Annual rent - All costs - Tax) ÷ Property price) × 100
The costs included in a proper net yield calculation are:
- Property management fees (typically 8–12% of rent)
- Maintenance and repair provisions (1–2% of property value per year)
- Insurance (landlord policy, structure, liability)
- Void periods / vacancy allowance
- Service charges, ground rent (if leasehold)
- Mortgage interest (if leveraged)
- Income tax on rental profits
- Accounting and legal fees
A property showing a 7% gross yield in a market with 30% income tax, 10% management, and 1.5% maintenance could deliver only 3.8% net — comparable to a 4.5% gross yield property in a tax-free environment.

Note: Net yields assume unleveraged ownership by a non-resident investor in a typical mid-range tax bracket. Section 24 impact modelled for UK leveraged landlords would further reduce UK net yield.
How to Calculate Rental Yield for Cross-Border Comparison
Step 1: Establish the Annual Gross Rent
Convert to a common currency (typically USD or EUR) using the current exchange rate. For properties marketed in local currency, note the USD equivalent and model FX scenarios — a 10% currency depreciation would reduce your USD return by roughly 10% on both rent and capital value.
Step 2: Apply Vacancy Allowance
Realistic vacancy rates:
- UAE: 3–6% (high demand, but seasonal in some areas)
- UK: 2–4% (tight supply in major cities)
- USA: 5–8% (city-dependent; Sun Belt cities lower than Midwest)
- Canada: 1.5–3% (historically tight, especially Toronto/Vancouver)
- Australia: 1–3% (low nationally; higher in some Queensland markets)
Step 3: Deduct Operating Costs
Management: 8–12% of collected rent. Add maintenance reserve (1% of property value per year is a conservative standard), insurance, service charges, and accounting.
Step 4: Apply Tax (the Critical Step)
This is where most DIY calculators fall short. The applicable tax depends on:
- Your tax residency
- Whether a DTT applies
- Local withholding requirements
- Available deductions (depreciation, mortgage interest)

Dubai's zero-income-tax environment is its most powerful advantage. The transaction costs (4% DLD fee + ~2% agent) are recovered within 6–12 months of rental income at typical yields. Service charges in major developments add 1.5–3% of annual rent as ongoing cost, but the absence of income tax means net yield stays within 1.5–2 percentage points of gross — far better than any other major market.
Example: Dubai off-plan investment
- Property price: AED 1,500,000 (~$408,000)
- Annual rent: AED 105,000 (~$28,600)
- Gross yield: 7.0%
- Service charge: AED 12,000
- Management: AED 9,450 (9%)
- Net rent: AED 83,550
- Income tax: AED 0
- Net yield: 5.6%
UK: The Section 24 Headwind
London offers access to deep mortgage markets (up to 75% LTV for non-residents with some lenders), but Section 24 devastates leveraged returns. An Outer London flat at 5% gross yield, financed with a 60% LTV mortgage at 4.5% interest, produces a net yield of approximately 0.8–1.5% for a higher-rate taxpayer — barely covering costs.
Unleveraged UK property makes more sense for wealthy investors who can absorb the income tax on gross profit, rely on long-term capital appreciation (London compound growth: ~4% annually over 30 years), and hold through cycles.
Practical Yield Comparison Tool
Bordex's International Rental Yield Calculator lets you input:
- Property price (in local currency or USD)
- Monthly rent
- Your tax residency
- Whether ownership is personal or corporate
- Mortgage details (if leveraged)
And outputs:
- Gross yield
- Net yield (after all costs and applicable taxes)
- 10-year annualised total return (yield + estimated capital growth)
- Side-by-side comparison across all 5 markets at the same investment amount
Conclusion
International yield comparison without tax modelling is meaningless. A 7% Dubai gross yield beats a 4.5% London gross yield by a wide margin — but a 4.5% London yield in the right corporate structure, with efficient depreciation and leveraged financing, might compete for investors who value sterling liquidity and UK mortgage access.
