Optimistic ignores vacancy. Base uses INSEE vacancy when available. Pessimistic cuts rent 10%, lifts charges 20%, adds vacancy, and +1 pp on the rate if financed.
INSEE vacancy mapped to months: 0.8 mo/yr
| Optimistic | Base | Pessimistic | |
|---|---|---|---|
| Net yield | 5.1% | 5.1% | 4.3% |
| Net-net | -0.5% | -0.9% | -3.0% |
| Monthly cashflow (levered) | -€163 | -€163 | -€558 |
| After 30% illustrative tax (30%) | €1,120 | €1,037 | €687 |
| Vacancy used | 0.0 mo/yr | 0.8 mo/yr | 2.8 mo/yr |
The 30% line is a labeled haircut on unlevered net after vacancy. Not tax, IR, or LMNP advice.
Four named shocks, then all at once: rent −10%, rate +2 pp, +6 months vacancy, works +15% on price.
The combined shock turns levered cashflow negative. Reprice or pass.
