Real estate rental is divided into successive decisions, the financial impact of which varies greatly depending on the type of lease chosen, the profile of the targeted tenant, and the management method selected. Comparing these parameters before publishing an advertisement helps avoid months of rental vacancy or disappointing returns. This article measures the concrete differences between the main options available to a landlord.
Unfurnished, furnished, or mobility lease: comparative table of the three formulas

The choice of lease type determines the duration of commitment, applicable taxation, and the profile of candidates. Rather than treating each option in isolation, a direct comparison helps identify the formula suited to your property and your strategy.

| Criterion | Unfurnished rental | Classic furnished rental | Mobility lease |
|---|---|---|---|
| Minimum lease duration | 3 years (6 years for a SCI) | 1 year (9 months for a student) | 1 to 10 months, non-renewable |
| Main target audience | Families, established professionals | Students, young professionals, expatriates | Interns, relocations, training |
| Tenant turnover | Low | Medium to high | High by nature |
| Security deposit | 1 month’s rent excluding charges | 2 months’ rent excluding charges | No deposit allowed |
| Flexibility for the landlord | Limited (long notice period) | More flexible (shorter lease) | Maximum (short duration, no renewal) |
The unfurnished rental offers income stability over several years. In contrast, the furnished option often generates a higher unit rent due to the provided equipment, which partially compensates for the more frequent turnover.
The mobility lease, still underutilized by many landlords, targets a mobile clientele (professional training, internships, temporary assignments). The absence of a security deposit may seem risky, but this lease is aimed at profiles often covered by a Visale guarantee or an employer. To delve deeper into the specifics of each formula, resources like the rental page on Immo et Moi detail the obligations specific to each regime.

Tenant solvency: the real lever to reduce the risk of unpaid rent

Selecting the tenant is the most structuring decision in a rental process. Competitors talk about “finding a good tenant,” but the reality lies in analyzing the application, not in the impression left during a visit.
The rent should not exceed a significant portion of the candidate’s income. The rule commonly applied by professionals is to verify that the remaining income after paying rent is sufficient to cover current expenses. A candidate whose income is just enough relative to the requested rent presents a significantly higher risk of unpaid rent, even with a guarantor.
Documents to analyze in the tenant’s file
- The last three pay slips or, for a self-employed person, the last two tax notices, allow verification of income regularity and not just its occasional amount.
- The employment contract (CDI, CDD, temporary) provides an indication of the stability of the professional situation, which weighs as much as the gross income level.
- The certificate from the previous landlord or the rent receipts confirm the payment history, a more reliable indicator than a simple declaration on honor.
- A valid identity document remains mandatory, but it also serves to cross-check the information from other documents.
A landlord who only looks at the salary amount without cross-referencing these elements exposes themselves to unpaid rent as early as the third or fourth month. Systematically cross-referencing income, professional stability, and rental history significantly reduces this risk.
Setting the rent: gap between personal estimation and local market price
The majority of landlords overestimate their property when first renting it out. An excessively high rent leads to prolonged vacancy, the cost of which quickly exceeds the expected rent difference.
To properly calibrate the amount, you need to compare your property to similar rentals in the same geographic area: same surface area, same floor, same level of equipment. Online listings allow for this comparison, but be careful to distinguish between advertised rents (often negotiated down) and rents actually charged.
In areas subject to rent control, the landlord cannot freely set the amount. Cities like Paris or Lyon apply a ceiling by neighborhood and by type of housing. Exceeding this ceiling exposes the landlord to forced compliance and reimbursement of overcharges to the tenant.
Rent and rental profitability
Setting a rent slightly below the market may seem counterintuitive. Conversely, this strategy attracts more applications, allows for better profile selection, and reduces rental vacancy. Over a full year, a property rented for twelve months at a reasonable rent yields more than a vacant property for two months at a high rent.
Also include recoverable charges in your calculation. A rent inclusive of charges simplifies management but sometimes masks an underestimation of provisions. Detail the recoverable items from the lease to avoid disputes at the end of the year.
Rental advertisement and inventory: two documents that protect the landlord
The advertisement is not just a marketing tool. It legally binds the owner to the description of the property, its surface area, and its equipment. An imprecise or exaggerated advertisement can be contested by the tenant after the lease is signed.
Specify the exact living area (measured according to the Carrez law for condominiums), the amount of rent excluding charges, the amount of charges, the type of heating, and the energy class from the DPE. These mentions are mandatory, and their absence can lead to the nullity of the advertisement.
The entry inventory, conducted jointly with the tenant, constitutes the only admissible proof in case of disputes over damages. A hastily completed inventory (boxes checked in a rush, no photos) systematically turns against the landlord in case of a security deposit dispute.
Each room must be described separately. Note the condition of the walls, floors, ceilings, woodwork, sanitary and electrical equipment. Add timestamped photos for each observation. This document, signed by both parties, freezes the condition of the property at the time of key handover.
Real estate rental relies on measurable trade-offs: type of lease, rent level, quality of the tenant’s file, rigor of contractual documents. Each of these parameters directly affects the actual yield of the property and the level of risk borne by the owner.
