Rental yield is the most quoted and least understood figure in property investment. Understanding the difference between gross and net yield is the single most valuable piece of financial literacy a new investor can acquire.
Gross yield is annual rent divided by purchase price. A property costing £200,000 and renting for £1,000 per month produces £12,000 a year, a gross yield of 6%. It is simple, comparable and almost never what you actually receive.
Net yield subtracts the real costs of ownership: service charge, ground rent, management fees, insurance, maintenance provision, void allowance and compliance costs. On that same property, those might total £3,400 a year, reducing net income to £8,600 and net yield to 4.3%.
The gap between 6% and 4.3% is where investor disappointment lives. It is also where diligence pays: two properties advertising identical gross yields can differ by more than a percentage point net, purely on service charge structure.
A further step is return on capital employed. If you purchased with a 25% deposit, your invested capital is £50,000 plus costs, not £200,000. Net income after mortgage interest, divided by capital actually deployed, is the figure that tells you how hard your money is working.
Our rule is simple: never make a decision on a gross figure. Ask for the full cost schedule, model a realistic void allowance, and stress-test the numbers against a higher interest rate than the one you are being quoted.
