Two sliders: the target rent, the household income. We tell you what your file can say to a landlord — then draft the message to copy into the listing’s contact form.
It’s the highest rent you’ll write about: the application is judged where it’s weakest.
Incomes add up. Up to 5 tenants, as in the app.
This application won’t convince landlords2.2× the rent
Your income covers 2.2 times the target rent. Below 2.5 times, it’s better to stay silent on this than to quote a figure that hurts you.
What would make this application work
Optional — one sentence of the message depends on it. Leave it blank and it’s simply left out.
No AI writes this message: every sentence is calculated from your numbers.
The listing’s form already carries its own reference and your identity: the message doesn’t repeat them, it goes straight to the point.
The project. One sentence from those you picked in the calculator — or nothing, if you didn’t answer: never a hollow line.
Affordability. Up to two arguments, in the order they convince: household income if it’s above 2.5 times the rent, otherwise the guarantor or the Visale guarantee if that alone is enough. Always a threshold — “more than 3 times the rent” — never an exact amount.
The request. A way to reach you directly, to move past the portal’s form and arrange a viewing.
No. No law sets a ratio: it’s a market practice, applied by most agencies. What is regulated is the list of documents a landlord can ask a candidate for — French decree no. 2015-1437 of 5 November 2015 sets it exhaustively.
Because a figure that hurts your case is worse than saying nothing. Below that threshold, the mention of income disappears from the message rather than show a weak ratio: what’s left is the project, job stability, and any guarantee. It’s exactly the threshold Swappart itself applies when writing to landlords.
Several options, in this order. The Visale guarantee, free and open to most people under 30 regardless of employment status (Action Logement) — check your eligibility on visale.fr. Failing that, a paid rent guarantee service such as Cautioneo or GarantMe, which act as a guarantor even without anyone in your circle to do it. Or a personal guarantor earning at least 3 times the rent. The tool also shows the highest rent your income covers on its own, without any of this.
The verdict is calculated in your browser: nothing is sent while you adjust the sliders. To draft the message, your numbers are sent once, the moment you click “Generate”, to the service that writes the text — nothing is kept. The exact amount never appears in the result either: the message only states thresholds, like “more than 3 times the rent”.
