Gross & net rental yield for buy-to-let properties
Gross yield is simple: annual rent divided by property value. It's the headline figure used to compare properties quickly. Net yield is more useful: it deducts all realistic costs to show your actual return on the property value. A property with a 7% gross yield might deliver only 3–4% net yield once all costs are accounted for.
Gross yield benchmarks vary widely by location. London: 3–5%; South East: 4–6%; Midlands and northern cities: 6–9%; some northern towns: 8–12%. As a rule of thumb, gross yields above 7% are strong for UK residential property. Net yields (after all costs) of 4–5% are solid; anything above 6% net is excellent. Don't be seduced by very high gross yields in depressed areas — tenant demand, void risk, and capital growth potential matter as much as yield.
Gross yield: (annual rent ÷ property value) × 100. Simple and quick to calculate, useful for initial comparisons. Net yield: (annual rent − all annual costs) ÷ property value × 100. Costs typically subtract 25–45% from gross rent. If a property generates £12,000/year gross rent but costs £5,500 per year (mortgage interest, agent, maintenance, insurance, voids), the net profit is £6,500. On a £200,000 property, that's a 3.25% net yield vs 6% gross.
Gross yield = (Monthly rent × 12) ÷ Purchase price × 100. Example: £900/month × 12 = £10,800/year. £10,800 ÷ £180,000 × 100 = 6.0% gross yield. Net yield: subtract all annual costs from £10,800. If total annual costs are £4,500 (mortgage interest, agent 10%, maintenance £1,500, insurance £300, 4-week void), net income = £6,300. Net yield = £6,300 ÷ £180,000 × 100 = 3.5%.
Buy-to-let remains viable but requires more careful analysis than it did a decade ago. Section 24 (tax changes limiting mortgage interest relief for higher-rate taxpayers) means highly leveraged portfolios face a much higher tax burden. Higher mortgage rates in 2024–2026 have squeezed cash flow significantly. EPC requirements (properties must achieve EPC rating C or above to rent legally after 2028) may require upfront capital expenditure. Despite this, strong rental demand, shortage of housing supply, and long-term capital growth in quality areas continue to attract investors. The key: buy in areas with strong rental demand, aim for higher yields, and run the numbers carefully.
Comprehensive cost checklist: mortgage interest (not capital repayment for cash-flow calculation); letting agent fees (8–12% for let-only, 12–18% for full management); annual maintenance budget (1% of property value is a common rule of thumb); landlord building and contents insurance (£150–£400/year); annual gas safety certificate (£60–£100); EICR (electrical inspection, £150–£250, every 5 years); void periods (budget 4–8 weeks/year); ground rent and service charges (leasehold flats); property management for self-managing landlords (time cost); and income tax on profits. Don't forget acquisition costs (SDLT second home surcharge, legal fees, survey) and eventual capital gains tax when modelling total return.
