HMO Rental Yield Calculator
House in multiple occupation yield.
Calculate HMO rental yield from property price, rooms, weekly rent, and expenses. Enter rooms let to see hmo gross and net yield from property price.
What this tool does
This calculator models the rental yield on a property divided into multiple occupied rooms. It computes both gross and net yield percentages by taking your property price, number of rooms generating income, weekly rent per room, annual weeks of occupancy, and total operating expenses. The result shows what percentage return the property generates annually in rental income relative to its purchase price. Gross yield reflects income before expenses are deducted; net yield accounts for them. The calculation is useful for comparing income-generating properties or testing how changes in occupancy, rent rates, or expenses affect returns. Note that the result assumes stable occupancy and rent levels, does not model capital appreciation or depreciation, and excludes financing costs, tax treatment, maintenance variability, and local regulatory requirements.

HMO (House in Multiple Occupation) yield = total rent across all rooms ÷ property price. HMOs typically yield 8-15% gross vs 4-7% for standard buy-to-let. Higher yield reflects higher management intensity (multiple tenants, more turnover, council licensing requirements) and higher expenses.
250k property, 5 rooms × 130/week × 48 weeks = 31,200 annual rent. Less 6,000 expenses (council licence, repairs, voids, communal cleaning, broadband) = 25,200 net. Gross yield 12.5%, net yield 10.1%. Strong returns - higher than standard BTL but more management work.
HMO regulation: licence required for 5+ tenants, some councils require licence for 3+. Article 4 directions in some areas restrict converting houses to HMOs. Fire safety regulations strict (interconnected smoke alarms, fire doors). Higher mortgage interest rates than standard BTL (typically 0.5-1.5% premium). Despite challenges, yield premium often justifies extra effort for active investors.
Quick example
With property price of 250,000 and rooms let of 5 (plus weekly rent per room of 130 and weeks let annual of 48), the result is 10.08%. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Property Price, Rooms Let, Weekly Rent per Room, Weeks Let Annual, and Annual Expenses. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
What's happening under the hood
Annual rent = rooms × rent × weeks. Net rent = annual - expenses. Net yield = net rent ÷ price × 100. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Where this fits in planning
This is a "what-if" tool, not a forecast. Use it to test ideas before committing: what happens if the rate is 2% lower than hoped, what happens if you add five more years. The value is in the scenarios you run, not the single answer you get from the defaults.
What this doesn't capture
Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. The number represents one scenario rather than a forecast.
5 × ££130/wk × 48wk - ££6,000 ÷ ££250,000 = 10.08%.

Sources & Methodology
Methodology
This calculator computes rental yield by first determining total annual rental income, then deducting operating expenses to arrive at net income, and finally expressing this as a percentage of the property price. Annual rental income is calculated by multiplying the number of rooms let by the weekly rent per room by the number of weeks the property is let annually. Annual expenses are then subtracted from this figure to derive net annual income. The yield is computed by dividing net annual income by the total property price and multiplying by 100 to express the result as a percentage. The calculator assumes a constant weekly rent throughout the let period, consistent occupancy across all rooms, and that expenses remain stable year-on-year. It does not account for void periods, maintenance variability, tax implications, or changes in rental rates over time.
