Housemate red flags — catch them before you sign anything
By Ted — founder, Rumy · Updated 25 July 2026
Most share-house horror stories were visible at the inspection; people just wanted the room enough to squint past them. The two rules that prevent nearly all of it: never pay anything before you've seen the room and met a human, and treat "too easy" with the same suspicion as "too hard".
Here are the flags that matter, sorted by where you'll meet them — and which ones aren't flags at all but straight-up scams.
Money flags — some of these are scams
Real households are relaxed about money before you commit and precise about it after. Scammers are the opposite: urgent before, vanished after.
- Asked to pay bond, rent or a "holding deposit" before you've inspected or met anyone in person: walk away. This is the classic rental scam, full stop.
- "The landlord's overseas, pay and the keys will be couriered": a scam with decades of service. No legitimate arrangement works this way.
- Pressure to transfer money to "secure your viewing time": viewings are free everywhere on earth.
- Bond with no receipt and no written record of the amount: even between friendly flatmates, no paper means no bond when you leave.
- Cash-only rent with no record: fine for some households, but insist on a written note of what's paid — protection runs both directions.
Ad flags
- No photos of the kitchen or living room. You're joining the common areas; hiding them is a choice.
- Rent dramatically under the suburb's going rate: sometimes a genuine bargain, usually bait. Check the room against live listings in that suburb before you get excited.
- The room count and the bathroom count don't appear in the same sentence. Seven bedrooms, one bathroom is information you deserve early.
- Location given as a vibe ("inner north-ish!") rather than a suburb. Vagueness in ads is rarely accidental.
- Re-posted constantly for weeks. Rooms that never fill have a reason you'll learn on day one.
Inspection flags
- You can't meet the people you'd actually live with — "they're all out" once is life; twice is policy.
- The current housemates clearly didn't know you were coming. A household that doesn't communicate about who's moving in won't communicate about anything else.
- "Three other people are seeing it at five, I need an answer now." Real demand exists in Melbourne, but manufactured urgency at the human level is a negotiation tactic — decide on your own clock, even if that clock is fast.
- You're shown the room but conversation about bills, guests or how the house runs keeps sliding away. Slipperiness now is slipperiness later.
Interview flags
These cut both ways — a sharp applicant is checking the household for them too.
- Every answer is "easy-going": you've learned nothing, on purpose or not.
- Every previous housemate was apparently a nightmare: notice the common denominator.
- Money questions answered with charm instead of specifics.
- No questions back about how the house runs. Curiosity is what commitment looks like at this stage.
First-weeks flags — and what to actually do
Some flags only show after move-in. The response to all of them is the same: early, specific, in person. Passive-aggressive is a flag; being direct about a problem is not — it's the fix.
- The bills arrangement everyone agreed to verbally keeps not making it into writing: set it down now — the free VIC flatmate agreement has a clause for exactly this.
- The "couple of nights" guest enters week three: name the norm, kindly, before it calcifies.
- Notes on the fridge instead of words in the kitchen: answer the note in person, without heat.
- Your rent or bond receipts stop appearing: re-establish the paper trail immediately.
The compounding rule
One flag is a conversation; three flags is a pattern; a pattern at inspection stage is a preview. The cost of walking away is one more Saturday of looking. The cost of ignoring a pattern is a year of it — priced weekly, paid in advance.
The inverse holds too: a house that's precise about money, honest about its rhythm, and introduces you to everyone has already shown you how it handles the important things. That's the green flag that outweighs a small kitchen.
