Opinions on the floor plan - double bungalow for rent

Economically, I don’t care about certain disadvantages up to a certain degree if I can use the apartment myself in old age. I only see that with a bungalow.

I strongly advise you against mixing the wishes of renting out and later personal use.

From your experience, can you say what deficit might arise when comparing a bungalow to a 1.5-apartment for rent of the same size? Or how can something like that be determined?

As I said, duplex bungalows have no market. Renters looking for duplex houses are the same target group as buyers of duplex houses. That means people who want a house instead of an apartment and just currently can’t find their own plot. For them, a converted attic is not a burden but a feature. Bungalow seekers do not want "wall-to-wall," but their peace on the property. And they want to invest their own capital, basically to live in their own money. That’s why I see your yield risk exactly in “two out of two housing units being vacant.” We once had a thread here – you were already on board then – with a four-apartment duplex. Something like that works on the rental market, but your single two-apartment rental floor does not. Basically, you are planning a six-family house where the upper apartments above the ground floor and the basement are missing. Why do you think this building type is not popular?

0.4 was actually an old value (from our development area).

Aha. First 0.4 and now 0.3 in another newly developed area with a similar structure – what does that say about the planning intent of the land-use plan issuer? – they want less sealing, never dream of a generous floor area ratio II! Be glad you don’t have the plot on your hands yet. Invest the money for the plot and the duplex bungalow into a medium-sized and two small condominiums; you will be happier with that.
