@deebouchie In your example I would assume you bought a 2 bed 2 bath apartment, even in a decent area most guests/tenants wouldn't be willing to pay more than 1k per month for a bedroom. The rent a room scheme is inclusive of utilities meaning that if you charge €900, you would need to subtract internet/gas/electricity from your profit.
The cons I see are:
- less privacy
- you'll have to share the fridge and the living space
- it'll be difficult or almost impossible to have family or friends over to stay overnight at a place you own
- sharing the kitchen and kitchenware
- unexpected maintenance costs
- potential careless/untidy tenant
Considering an optimistic net profit of 750 per month, that's 45k in 5 years.
Would you be willing to share the place you bought with so much effort for 5 years for 45k?
In my case, I would only consider it if I really needed the money for renovations or if the person living with me was a close friend.
