You buy an apartment. And a co-ownership.

01Documents tell the building’s story

Notaries list information to receive before the offer or sale agreement: funds, arrears, approved calls, pending proceedings, minutes and accounts. These explain the collective obligations attached to the unit.

Ask your notary and property manager to identify missing documents. Do not confuse a forecast budget, annual accounts and the status of funding calls.

02Read decisions, not just the total

For each important issue, distinguish discussion, decision, quote and funding call. Ask what was approved, what remains to finance and the allocation shares. Recent minutes may tell a different story from the advertised monthly charge.

The allocation of costs between seller and buyer must be clarified in the sale file, not inferred from a sentence in the listing.

03Your practical reading grid

Build a three-column table: issue, supporting document and question to resolve. Make unknowns visible and identify who can answer.

• Roof, façade, lift: condition and planned works?
• Accounts: which expenses recur each year?
• Decisions: which works were approved?
• Financing: which reserves and calls?
• Disputes: which matters are reported?

04What changes in your simulation

Separate operating costs from one-off capital expenditure. A significant future cost must not disappear behind a routine monthly provision. Give it its own assumption, timing and source.

A sound file does not always mean walking away. It may lead to a different price, financing or order of checks. Documents make that choice possible.
