230 m² Paris apartment or similarly priced duplex?

My main constraint is the amount of time and cash I can absorb when maintenance arrives unexpectedly. Against that, I’m weighing a 230 m² Paris apartment and a similarly priced duplex.

The apartment may spread some work through the co-ownership, although that also means shared decisions and possible calls for major projects. The duplex could provide greater independence depending on its legal and physical setup, but it may put more maintenance directly on the owner. I’m comparing reserves, insurance, energy use, vacancy, tenant demand, resale prospects and management effort. Which building records, bills or ownership details would best expose the costs that are easy to miss in year one?
 
For the apartment, look beyond the current annual charges. Read recent co-ownership meeting records for discussed façade, roof, lift, heating or common-area works, including proposals that were postponed rather than cancelled. A healthy reserve does not necessarily cover every project.

For either property, request actual energy bills across seasons and clarify exactly what the insurance covers. At 230 m², inefficient heating can matter more than small differences in routine maintenance.
 
What exactly is meant by duplex here: a two-level unit within a shared building, or a property with its own roof and exterior? If it remains in co-ownership, the supposed extra control may be limited while you still accept stairs, more internal surface to maintain and shared-building costs.

I’d also challenge the assumption that the apartment is automatically easier to resell. Layout, floor access and running costs could outweigh the property label.
 
Agreed on clarifying the legal and physical setup, but I would not dismiss the stairs as a minor detail. They can narrow both the tenant and resale audience compared with a well-arranged single-level apartment, especially at this size.

I’d compare them on one sheet: five years of known or discussed building works, responsibility for roof/windows/exterior, realistic energy bills, insurance exclusions, management tasks, and likely buyer or tenant groups. Then stress-test one major repair and a longer vacancy. That should expose whether “more control” is actually worth the concentrated risk.
