My first flat was a studio behind the port, thirty square metres, and I signed for it in a hurry because a friend of a friend was leaving and it felt like a scoop. What I had not worked out was how much money leaves your account in the same week you get the keys. That is the number nobody tells you.
In brief
- Day one costs far more than one month’s rent.
- The “three times the rent” rule has no legal basis.
- Photograph everything before you unpack a single box.
- A bail mobilité takes no deposit at all.
Start with the day-one number, not the monthly one
The figure that trips up first-time renters is not the rent. It is the pile of payments that all land at signature.
| What you pay at the start | Typical scale in France |
|---|---|
| First month’s rent and charges | One month, often pro rata |
| Security deposit | One month unfurnished, two furnished, charges excluded |
| Agency fees, where an agency is involved | Capped per square metre by decree, by zone |
| Home insurance, compulsory before the keys | Annual premium, often paid upfront |
| Utilities and internet activation | Setup costs, sometimes a first bill |
Add a van, a mattress and the fact that nothing in an unfurnished French flat includes a light fitting, and you can see why the first week hurts. Work that total out before you start viewing, because it changes which rents you can actually reach.
Budget rules, and where they stop being useful
Two rules matter here and they answer different questions.
The 50/30/20 rule, popularised by Elizabeth Warren and Amelia Warren Tyagi in their 2005 book All Your Worth, splits after-tax income into 50% needs, 30% wants and 20% savings and debt repayment. It is a sanity check on your whole budget: if housing alone eats most of the 50%, transport and food have nowhere to go. Useful for deciding what you can sustain.
The rule that decides whether a landlord picks you is different and blunter. French landlords and agencies conventionally look for a net monthly income of at least three times the rent, which mechanically puts the rent-to-income ratio under about a third. Worth knowing precisely: this has no legal basis. Neither the civil code nor the housing legislation imposes it, it is a market habit, and it is lawful only as long as it is applied to every candidate alike and not used as cover for discrimination. Knowing it is custom rather than law will not get you a flat on its own, but it tells you that a solid guarantor or a strong file can compensate.
Where to actually look
Portals cover different ground depending on the city, so use more than one and check each is still active before you rely on it.
In the United States, Apartments.com covers the widest national footprint, while city-specific platforms have historically been where the real inventory sits: StreetEasy and Nooklyn both grew out of the New York market and know it far better than any national aggregator. Rental platforms come and go, so confirm a site is still operating before you build a search around it.
Two methods that no portal replaces. Walking the streets you actually want to live in and photographing the agency boards, which is how I found two of my three flats. And asking people already living in a building you like, because the flat that comes up in June is often let before it is ever advertised.
Viewings: twenty minutes, used properly
Spread tours over two days rather than cramming them into one afternoon. After the fourth flat they blur, and you will remember a terrace and forget a boiler.
What to check while you are inside, in rough order of how expensive it is to discover later:
- Damp: corners behind furniture, the ceiling of the bathroom, the back of built-in cupboards.
- Water pressure: run the shower and a tap at the same time.
- Heating: what type, who pays for it, and what it costs the current occupant.
- Noise: open a window to the street, and ask what is directly above and below.
- Sockets and light fittings: count them, because retrofitting either is not your job as a tenant.
- Phone signal: check it standing where the bed will go.
Film a walkthrough on your phone with the commentary out loud. It is the only reliable way to compare four flats a week later, and it costs nothing.
The lease, and the document your deposit depends on
Read the lease properly, and treat the inventory as the more important of the two papers.
The état des lieux d’entrée is annexed to the lease and is the reference against which your deposit is judged when you leave. Do it slowly, in daylight, and photograph every mark, every scuffed skirting board and every appliance you are handed. Note meter readings on the document itself. The moment to be pedantic is the day you arrive, not the day you leave.
If anything was promised verbally, a free first month, a repaint, a repair before entry, it belongs in writing in the contract. A verbal promise from a departing agency is worth exactly nothing three months later.
The shortcut worth knowing if you are only staying a while
For students, people on temporary assignment, apprenticeships or internships, the bail mobilité is a furnished lease of one to ten months created by the ELAN law. It cannot be renewed or extended past ten months, and the landlord is not allowed to ask for any security deposit at all, though a guarantor is still possible through the Visale scheme. On a coast where seasonal work and short postings are common, that removes the single biggest cash barrier to a first flat.
Move-in week, in order
- Take out home insurance before signature, since the landlord can require proof of it.
- Do the inventory and keep your own dated copy, photographs included.
- Open the electricity, gas and water accounts in your name from the day the lease starts.
- Register your new address with the bank, the post and, if you are new to France, the town hall for anything local.
- Find out where the bins go and when. It sounds trivial until your first Sunday evening.
What I wish someone had told me at twenty-two: nothing about the first flat is permanent, so stop optimising for the perfect one. Optimise for a lease you understand, a deposit you can afford to leave sitting there for a year, and a building where somebody answers the door when the plumbing fails in August.
