What is cheaper? Single-family house or two-family house?

Good morning, for some time now I have been diligently paying into my home savings contract and have been wondering all along whether it is cheaper in the long run to build a single-family house or to build a two-family house right away in order to rent out the second half. In terms of pure construction costs, it will definitely be more expensive, but whether it will pay off later and I will have recouped the costs is the question that occupies me. Does anyone have experience with this?

That entirely depends on the additional costs for the apartment or on the rental situation where you are... If the rents are quite low where you are and you often have to expect vacancies, then it will of course pay off later, unlike if you can ask for a fairly high rent...

Regardless of that, you should also consider whether you really want to do it... many build a single-family house because they no longer want to live together with strangers in one house... and of course you will also have a certain amount of extra work with it!

I can only agree with my predecessor. You should ask yourself if you want to live house to house with a stranger.

If you can be sure to always rent out the apartment and do not catch any [Mietnomaden], a two-family house is significantly cheaper.
