In this area, according to several rental price indexes and real estate agent information, the rent would be around €11-12 per square meter (about $12-13 per square foot), which equals roughly €400 (about $440) cold rent plus possibly a carport space, with a yield of approximately 5%.
Great, then you would roughly break even after 20 years. The downside is that you constantly have to renovate with student tenants, and after 20 years, you essentially have to gut the property.What bothers me is the garden access, or rather the lack of it.
The roof terrace is nice for eating and having coffee.
But what about the children?
Sandbox, slide, etc.
Always having to go through the entire house just to get a glass of juice?
Parents are always sitting there and can’t do anything, not even join for dinner.

How did you calculate the 5% return? The money for building the granny flat has to be raised first. Taxes also apply, plus maintenance.That's correct. Already included in the future household budget. Reserves for maintenance, rental vacancies, insurance, etc.kaho674 schrieb:

setting aside reserves for maintenance + covering potential rental losses + withholding the security deposit as a backup + using second-hand but good-quality fixtures and fittings found on sites like Ebay Classifieds for the rented self-contained unit + doing some of the work yourself here and there.

During my studies, three of us students even lived together in a basement flat share (3 rooms, 1 bathroom, 1 kitchen) in a family’s detached house. Then you know what your family can look forward to.

With a separate entrance to the granny flat and the main living area, contact with the landlord (despite having two children) was barely noticeable for all of us. Here, however, it is very noticeable: on the one hand, you drive your cars to his garage entrance, then what?... pass by the apartment and walk around the house to get inside, or go through the storage basement. Which is nicer? I find this completely thoughtless. Who wants to enter their home by walking through a storage or utility room, stumbling over some stored play or sports equipment? And then possibly have someone curiously listening through the connecting door to the granny flat?! Or just walk around half the property?
On the ground floor, the garden can only be accessed through the front door. You don’t need to build for that. For me, that is inadequate.
Although the ground and upper floors are quite large, the staircase is rather modest, which is not necessarily negative. I find the living-dining area too large... uncomfortable. Too far from the kitchen.
At the moment, I can’t decide whether these large rooms are a positive/generous feature or just oversized. I don’t want to only criticize, but for a sense of spaciousness in a house, in addition to large rooms, I expect some highlights like an open staircase, an atrium, or an open gable. If those aren’t present, as here, I would rather plan the rooms at a “normal” size.
For me, the biggest flaw of the house is the lack of a direct connection between the living spaces and the garden, whereas the granny flat is clearly the central point for the family.
