In my opinion, it depends a lot on what kind of people you are. Rather perfectionists, urban, aesthetes, everything has to look impeccable, adaptable and tolerant regarding neighbors and their needs (then 2) or can you live with visual imperfections at first (then 1).
So far, I vote for 1 for the following reasons:
- We currently live in a property from 1945 where the heating pipes are partially laid on the surface. It does not bother us and we live just as well as if they were laid under the plaster. But for that, we have a detached single-family house, a large plot, a good location, neighbors further away.
- I think about: What is changeable and what is not? The large plot, the location, no neighbors or potential neighborhood conflicts, a high degree of self-determination and freedom in the design of the interior and exterior, the possibility to rent out a granny flat, and much more no one can take away from you. And everything else can be changed with time, motivation, yes, and also money.
- I neither appreciate semi-detached houses nor terraced houses.
- You can already negotiate the price. Maybe you will experience a positive surprise. Or you get offers for your desired changes and it is not as expensive as you thought. That was mostly the case for us, with our house. Maybe with the offers you can also negotiate the price down.
