Writing a listing for your spare room
Someone is moving out at the end of the month and you have twenty minutes to write the advert. The instinct is to describe the room — dimensions, light, the new mattress — and to keep everything else warm and unspecific so that as many people as possible reply.
That instinct produces the worst possible outcome: forty enquiries, thirty-five of which are from people the house will not suit, and no way to tell which five are which without spending six evenings finding out.
A listing is a filter, not an advert
You are not trying to maximise replies. You are trying to maximise the proportion of replies worth answering, which usually means writing something that actively deters people.
Every fact you leave out gets discovered eventually — at the viewing, in the second week, or in month four when it turns out the person who took the room needs quiet before ten and the kitchen is directly under their floorboards. Discovering it late is expensive for both of you, and the cost lands on you as well: a housemate who leaves in three months means doing all of this again.
So the useful test for every sentence is not does this sound appealing but would someone self-select out because of this, and would that be a good outcome? If yes, keep it in.
Describe the household, not only the room
The room is the part a photograph handles. The household is the part that determines whether this works, and it is almost always the part left blank.
Worth stating plainly:
How many people live here and who they are in the loosest sense — how many, roughly what stage of life, roughly what hours. Not names, not biographies.
Who holds the tenancy and what your position is — whether you are the owner, the head tenant, or one of several joint tenants. Say which. You do not need to explain what the category implies, and you shouldn’t try to; what it means legally varies by jurisdiction and a local tenant or housing service is the place for that. But the person reading needs to know who they would be dealing with, because the answer changes what they are agreeing to.
How the house actually runs. Whether people eat together or separately. Whether the living room is used or is effectively a corridor. Whether it is a house where the kitchen gets cleaned tonight or tomorrow. Whether anyone’s partner is around most of the week. This is texture, not rules, and it is the single most predictive thing you can write.
The availability date, and whether it is firm. “Available now” when the current occupant leaves in three weeks wastes everybody’s time and reads, later, as the first thing you were vague about.
What not to write here: the terms. A listing is not the place to set out who pays what share of which bill, how chores rotate, or how the deposit is handled between you. Those belong in something you agree in writing before anyone moves in, and working out what goes into that document is a subject for elsewhere. In the advert, one line — “we’ll put the arrangements in writing before you move in” — is enough, and it is quietly reassuring.
State the disadvantages in your own words
Every room has three or four things that will make someone say no. You get to choose whether they find out from you or from the doorway.
The room is small. It faces a main road. It is on the third floor with no lift. The bathroom is shared between four. There is a cat. The boiler is loud. The window is frosted. Someone works from home in the room next door and takes calls.
Writing these yourself has two effects. It filters out the people for whom each is a deal-breaker, which is the entire point. And it makes everything else you wrote credible, because a listing that admits a fault is read completely differently from one that doesn’t — see what a room listing tells you for the receiving end of that.
The phrasings to avoid are the coded ones. “Cosy”, “characterful”, “would suit a student”, “no drama”, “must be easy-going”. Experienced readers translate all of these, usually accurately, and the translation is worse than the fact.
Where the line on selection sits
You are allowed to choose on behaviour, logistics and preferences: hours, noise, how much shared life someone wants, whether they can afford the room, whether they can start on the date you need.
You are not choosing on protected characteristics — race, religion, national origin, disability, family status, sex, sexual orientation and their local equivalents. That is not a screening axis on this site, and if you are the one advertising, selection and advertising law may well apply to you directly. What it covers, and whether a live-in arrangement is treated differently, varies by jurisdiction; your local tenant or housing service will know what applies where you are. Check before you write a preference into an advert, not after.
The practical version: write about the household and the logistics, and let people decide whether they fit. Describing the house honestly does far more filtering than any stated preference, and it does it without putting you anywhere near that line.
Flag check
FLAG CHECK — reading back your own draft
· No photo of the actual room
→ flag to every reader. Assume
they think it is a scam.
· Price given as "negotiable" or omitted
→ flag. Reads as a bidding
process nobody wants to enter.
· Household described only as "friendly
professionals"
→ not a flag, but does no work.
Costs you the good enquiries.
· You mention the room is small and dark
→ NOT A FLAG. This is the
sentence that earns trust.
· You name the schedule clash you know
the room has
→ NOT A FLAG. It filters the
person it would fail.
· Draft asks for a deposit to reserve the
room before a viewing
→ WALK AWAY from your own draft.
This is the exact structure of
a scam and honest readers will
leave.
After you publish it
Where you put it changes who answers, so it is worth reading where rooms are actually advertised before picking one channel and refreshing it.
Then expect the enquiries to be mostly bad in a specific way: short, generic, and giving you nothing to go on. That is a property of the medium rather than of the people, and the ones that are specific about themselves are worth answering first. From there it becomes a process problem, handled in choosing between people when you have the spare room.
What a good listing can’t do
It cannot make the pool bigger and better at once. An honest, specific advert gets fewer replies than a vague warm one — that is the mechanism working, not failing, but if you need someone in the room by Friday it will feel like a loss.
It also can’t screen for the things nobody discloses about themselves. Nobody writes “I leave washing up for a week” in a reply to an advert, and no amount of care in your own text extracts it. The listing’s job ends at getting the right five people to write to you. Everything after that is conversation, and a conversation is a small sample too.
