The evidence chain for rent arrears, reminders and proceedings before a sale can affect income, leases, liability and price in an apartment building. A spreadsheet or verbal assurance is not enough.
The review therefore connects the evidence chain for rent arrears, reminders and proceedings before a sale with the lease, property file and handover. The starting point is section 1100 ABGB and sections 30, 33 and 37 MRG, applied to the specific lease; deadlines and claims are not inferred from a general assumption.
