How to Underwrite a Coliving Deal

8 stepsTwo to three days per building, done properlyFor operators and investors assessing a specific building

The short version

Run the legal filter before the financial one. Establish the lawful bed count — licensing threshold, planning position, minimum room sizes, amenity ratios — then model against that number rather than against the floor plan. Most coliving models that fail after exchange failed at step one, not at step six.

The most expensive coliving mistakes are made in the wrong order. Operators run the numbers first, get excited about the yield, and then discover the planning position or the amenity ratio has removed two beds from the model that made it work.

This is the sequence we use. It is deliberately front-loaded with the checks that can kill a deal outright, because a fast no is worth more than a slow maybe.

  1. 01

    Establish the lawful use before anything else

    Is the intended use permitted at this address? In England, three to six sharers is use class C4 and the change from a family dwelling is permitted development — unless an Article 4 direction applies. Two of the four UK cities in our cost index have removed that right citywide. Seven or more sharers is sui generis and always needs permission. In the US, the equivalent question is the unrelated-occupancy limit in the municipal zoning code.

    Where this goes wrong

    Check the address, not the postcode district. Article 4 boundaries can be ward-level and do not follow anything intuitive.

  2. 02

    Find every licensing scheme that applies

    Mandatory, additional and selective schemes are separate designations with separate fees and separate boundaries, and they change on their own timetable. Check the council's own live scheme rather than an aggregator, and note when the designation expires — a licence issued late in a scheme may not run the term you assume.

  3. 03

    Derive the lawful bed count

    Measure every intended sleeping room against the statutory minimums — 6.51 m² for one adult in England — and against the amenity ratios that apply locally. In Toronto that is one bathroom per four dwelling rooms, which caps rooms at compliant bathrooms multiplied by four regardless of what the floor plan shows. This number, not the plan, is what you model.

    Where this goes wrong

    Modelling the floor plan rather than the lawful count is the single most common way a coliving acquisition model turns out to be wrong by two beds — which is usually the difference between the deal working and not.

  4. 04

    Price the regulatory cost of opening

    Licence fee plus planning application fee where one is required. Across the UK cities we have indexed this runs from about £755 in Birmingham to roughly £2,486 in Bristol. It is small against acquisition and large against first-year cash, and it lands before any rent arrives.

  5. 05

    Build the rate from the catchment, not the city

    Comparable private rooms within a genuine commute of the same employers or campus. Regional averages are context: the ONS puts West Midlands average private rent at £971 a month, which tells you very little about a specific street. Model the achieved rate rather than the asking rate.

  6. 06

    Model the trough month, not the annual average

    UK coliving demand thins from late May to mid-August. A building averaging 90% across a year is often running low eighties in July, and if your debt service is level and your covenant is tested quarterly, the trough is what matters. Two to three points of annual occupancy movement is normal — the largest UK student operator went from 97.5% to 95.2% in one year with two decades of leasing history behind it.

    Where this goes wrong

    A model with occupancy flat for five years has a bug rather than a plan.

  7. 07

    Carry lease-up as a cost

    A first building in a market where you have no brand does not fill on the timeline a spreadsheet assumes. Our planning assumption is 45–70% average occupancy across the first six months, and that the revenue lost in ramp-up should sit in project cost rather than being treated as a delay.

  8. 08

    Stress it, then decide

    Take the lawful bed count, the achieved rate, the trough month and a five-point occupancy fall, and see whether the deal still services its obligations. If it only works at the base case, it does not work — you have found a building that requires everything to go right, which is not an investment thesis.

Before you apply this

What this sequence assumes

It assumes you are buying or leasing an existing building to convert or operate. A development scheme carries a different set of front-loaded risks — consenting route, programme, construction cost — and yield on cost rather than entry yield is the measure that decides it. Nothing here is legal, planning or investment advice; take it on the specific address.

Frequently asked

What should I check first when assessing a coliving property?+

The lawful use at that address — the planning position and the licensing schemes that apply. Everything financial depends on the lawful bed count, and the lawful bed count depends on those two answers. Running the numbers first is how operators end up with a model that assumes beds they are not allowed to let.

What occupancy should I underwrite at?+

The bottom of the band, not the top. Our planning ranges are 45–70% average through a six-month lease-up, 80–90% in year one, and 88–94% once stabilised. Underwrite the bottom and treat the top as upside — every operator we have watched get into trouble did the reverse.

How long does proper coliving diligence take?+

Two to three days per building for the checks above, most of which is confirming the planning and licensing position with the authority rather than modelling. That is time well spent against the cost of discovering an Article 4 direction after exchange.
