How Zemmer works
Zemmer helps people find a home in Luxembourg two ways: buying together with people who fit, or renting a room you can book for your dates.
Buying together
For people who cannot buy alone: we match buyers into a group, check it, and hand it to the selling agency.
- 1
Build your housing profile
Tell us your budget, savings and mortgage situation, and how you want to live. It takes about ten minutes.
- 2
Apply for a share
Pick the properties you like and the share that fits your budget. Apply alone or with people you already know.
- 3
Get scored against other applicants
We first check whether a group can afford the property together, then how well its members would live and own together.
- 4
Agree on the co-ownership terms
Your group negotiates the co-ownership agreement clause by clause on Zemmer, ready for the notary.
- 5
Hand over to the agency
Zemmer passes the qualified group to the selling agent, who completes the sale. Our fee is due only when the deal goes through.
Renting a room
No profile or finances needed. Pick your dates, see what is free and book.
- 1
Search by dates
Stays start on the 1st or 15th and end on the 14th or at the end of the month. Only rooms free for your whole stay are shown.
- 2
Pick a room
Photos, floor plans, rent, charges, deposit and a 12-month calendar for every room.
- 3
Book
Send your dates. Most rooms are confirmed at once and the dates are blocked for everyone else; some landlords approve each request themselves. Nothing is paid on Zemmer for now.
- 4
Move in
Sign the lease with the landlord, give them the deposit directly and pay the later months as agreed.
You pay the rent and the deposit (at most two months) directly to the landlord under your lease. Zemmer never holds your deposit. Online card payment will come later; we will say so here.
How the compatibility score works
Every applicant for a property is compared with every other applicant. Groups are ranked by a score out of 100.
Can the group buy together?
Combined savings must cover the deposit and purchase costs, each share must fit what its buyer can borrow, and the shares must add up to the whole property. A group that fails here is not proposed.
Will they live well together?
For buyers who will live in the property, we compare daily rhythms, cleanliness, noise, guests and how people handle money and disagreements. Dealbreakers such as smoking or pets rule a group out.
Do they want the same thing?
Owners need to agree on how long they plan to keep the property and when they want to buy, so timelines are part of the score.
For agencies
- 1
List the property
Add the property and how it can be split into shares. Our team reviews it before it goes live.
- 2
We build the group
Buyers apply, Zemmer scores them, proposes the best group and coordinates the co-ownership agreement.
- 3
You receive a ready group
You get the group, their agreed terms and their contact details, and complete the sale as usual.
What it costs
Browsing, profiles and applying are free. Zemmer charges only when a deal goes through: when a group buys a property, or when a room is let, with a commission on each month of rent taken from the landlord’s side.
