Coin flips aren't fair. "I called it" isn't fair. Seniority isn't fair. The only fair way to divide things people want differently is the old-fashioned way: supply & demand. Whoever values the balcony most pays for it — and whoever's happy in the small room gets paid for it through lower rent. Biddler runs that market for you in minutes.
Every auction is scheduled by its organizer, but the clock works differently by type. Silent room auctions and stuff auctions get a beginning and end date & time — bid or adjust any time inside the window, with the action converging near the close. Live room auctions get a start date & time only — once they begin, rooms sell one at a time on short clocks.
There are two ways to auction rooms, and the difference matters:
| ⚡ Live | 🤫 Silent | |
|---|---|---|
| When | Everyone on at once, ~10 min | Any time over up to 10 days |
| How you bid | Openly, in real time, room by room | Secretly, on every room, editable until the deadline |
| Clock | 30/60/90s per room + 20s overtime bids | One end date & time for everything |
| Winner pays | Their final winning bid | Average of the top 2 bids ± even settlement |
| Feels like | A game night with money on the line | Sealed envelopes and a dramatic reveal |
Both end the same way: everyone chose their price, and the totals equal the rent to the dollar.
Best for: deciding rooms fast, together, with maximum drama.
Setup: the organizer enters the total rent, the rooms (name + details so nobody ranks the wrong room), and invites the roommates. Everyone privately ranks the rooms from favorite to least favorite — the average ranking sets the auction order, best room first.
Bidding on the best room opens at the "everything is equal" price:
First bid claims PAR; every bid after raises it by the increment. When the clock finally runs out — remember, last-10-second bids extend it 20 more, as many times as it takes — the leader wins the room at their bid and is out of the bidding.
Then the magic — PAR recalculates before each new room:
If the master sells high, everyone else's starting price drops. The last person standing takes the last room and pays whatever's left:
— often the deal of the century.
A room with no bids goes to the back of the line for one more try. If it passes twice, it drops into the stalemate bucket. If every remaining room ends up stalemated, the organizer chooses: 🎲 randomize the remaining rooms at an equal split of the remaining rent (with a 15-second speak-now countdown), ⏸ pause and restart when everyone's ready (maximum 2 pauses — and on restart the bid increment drops to $3 so tiny bids can break the deadlock), or 🛑 end the auction and figure out a different way to resolve it.
Best for: groups in different time zones, conflict-avoiders, and anyone who'd rather not bid against a friend's face. You're really only bidding on the premium.
Instead of a live showdown, the organizer sets a start and end date & time, and everyone privately submits one bid for every room before the deadline. You can change any of your amounts at any time until the auction ends — nobody sees anyone else's numbers until the reveal.
Best for: selling your couch, bike, or half your closet before a move — to friends, not strangers.
The organizer sets a start and end date & time for the whole sale — up to 10 days. Every item lists with a posted reserve (minimum bid) that everyone can see. Invite friends — or open it to your followers.
PAR is the "everything is equal" price: total rent ÷ number of people. It's the anchor for every auction — live bidding opens there, and blank blind bids default to it. Bid above PAR for rooms you want, below for rooms you don't.
Usually the opposite. The last person pays Total Rent − everyone else's winning bids — and since good rooms tend to sell above PAR, the leftovers shrink. In our example house, the last roommate paid $850 on a $1,000 PAR without placing a single bid. Patience pays.
They almost never do — that's expected. The difference is split evenly: (Rent − Sum of Prices) ÷ Rooms, added to (shortage) or subtracted from (surplus) every room. Totals always land exactly on the rent.
The organizer chooses the rule at setup: a random draw, or "highest theoretical total" — sum each tied person's bids across all rooms, and the bigger total wins (they demonstrably valued the house most).
Live auctions: the room goes to the back of the line for a second chance; if it passes twice it enters the stalemate bucket, and if everything stalls the organizer randomizes at an equal split, pauses (max twice), or ends the auction. Blind bids: a room nobody bid on just resolves at PAR, since every blank defaulted there.
No. Any bid in the final 10 seconds of a clock extends it by 20 seconds, on every auction type. The clock only truly runs out when everyone's done.
Live room auctions start at the date & time the organizer picks, with a per-room clock of 30, 60, or 90 seconds (whole thing typically ~10 minutes). Blind bids and stuff auctions can stay open up to 10 days (240 hours) — the organizer sets the start and end.
In stuff auctions you set the most you'd pay and let Biddler do the bidding. If your max is $80 and the next-best bidder maxes at $50, you lead at $55 — not $80. You only ever pay one increment more than the competition demanded. And if your max is below the item's posted reserve, the bid won't register at all.
Never. Rent goes to your landlord; stuff-auction payments go directly between friends (Venmo, Zelle, cash). Biddler only charges its own fee to run the auction.
The organizer controls price reveals: show all (default), let each winner choose, or hide all. Names and selfies are always up to each person.
Every Biddler auction ends the same way: everyone chose their price. The person in the big room chose to pay for it. The person in the small room chose to save. Nobody flipped a coin, nobody pulled rank, and the math always adds up to the dollar. Supply & demand — settled.
