A buyer’s example
Check what changed when the flat was renovated
A freshly finished Kyustendil flat can look ready for winter on a viewing. Ask what work was done behind the finishes and what relates to the shared building. See whether the bathroom has working ventilation and ask about any recent work to windows or plumbing. Note which work has a dated record and which the seller describes from memory.
At a second flat, compare the same things before weighing the walk from the centre or Hisarlaka. If both properties suit your route, ask what each would need to be comfortable through a full winter. Have an appropriate tradesperson look at anything you cannot assess during the visit, and keep planned shared work in its own line of the budget.
