Lisbon duplex or serviced apartment: how should I price the hidden costs?

I’m nine days into comparing a 220 m² duplex with a similarly priced serviced apartment in Lisbon. My current impression is that the duplex would be simpler to maintain, while the serviced apartment offers more control but could leave me exposed to larger irregular bills.

I’m modelling insurance, energy use, local supply, tenant demand, vacancy and resale liquidity. The part troubling me is that the minutes mention “the work” three times without giving a firm estimate.

What would you put on a practical pre-purchase checklist, particularly for shared-building reserves and costs that tend to appear after the first year?
 
I would not treat that unexplained work as a minor detail. Ask what it covers, whether quotes exist, how the cost would be allocated and whether current reserves could cover any of it. Until those answers arrive, model a separate contingency rather than entering zero.

Also compare recurring management charges, what they actually include, likely furnishing or appliance replacement, and who handles problems between occupancies.
 
What is your intended use: personal occupation, a conventional tenancy, or frequent short stays? That changes almost every comparison. A serviced apartment may reduce hands-on work, but demand, vacancy and management costs depend heavily on how it will be occupied.

For the duplex, I’d also compare the usable layout rather than relying on 220 m² alone. Stairs and separated floors can narrow the future buyer or tenant pool.
 
I’m not convinced the duplex is automatically the simpler option. Two levels can mean more heating and cooling zones, more internal circulation, and potentially more maintenance points. The serviced apartment may have more shared costs, but some routine workload could sit within its service structure.

The real distinction is predictable monthly spending versus occasional large building bills. Those need separate columns in your model.
 
Insurance deserves a like-for-like comparison. Establish what the building policy covers, what remains with the owner, and whether the intended letting pattern changes the cover or price. The answer may depend on the building and insurer, so assumptions are risky here.

For resale liquidity, consider who would buy each property. The duplex may appeal to space-led buyers; the serviced unit could have a narrower audience if ownership comes with operating conditions.
 
Building on Anders’s point, I’d request earlier minutes and reserve information, then trace whether “the work” is a new issue or something repeatedly deferred. Three mentions without an estimate are enough to treat it as unresolved, not hypothetical.

I’d run two budgets for each property: an ordinary year and a bad year involving vacancy, higher energy use, an insurance excess, appliance replacement or a shared-building contribution. That makes the trade-off much clearer than comparing average annual costs.
 
When you say the serviced apartment gives more control, control over what exactly? Occupancy, pricing, choice of manager, interior works and the timing of sale may not all sit with the owner under every arrangement. I would list each decision you care about and confirm who can make it.

If the duplex is simpler only because it lacks a service arrangement, remember that simplicity can translate into more personal management workload.
 
One addition to my earlier question: test liquidity as a delay as well as a sale-price risk. If one property takes longer to sell or re-let, the carrying costs continue during that period.

My order would be: clarify the unidentified work, confirm what “control” means, compare ordinary and bad-year cash flow, then assess which layout and ownership structure has the broader future audience. Without the first two answers, the similar headline price is not a meaningful comparison.
