Good to know before investing in Belgium
- A main-residence lease must be registered (free of charge); the rental deposit is capped depending on the Region and its form (2 or 3 months of rent).
- Depending on the Region, energy renovation obligations may apply after the purchase: in Flanders, a home bought with EPC label E or F must reach at least label D within six years.
- Tax: a home let to a private person who lives in it is in principle taxed on its indexed cadastral income plus 40%, not on the actual rent; the owner still pays the property tax (précompte immobilier).
