A foreign family wanted a new house near Poznan with a mortgage. The listing looked perfect — without due diligence, bank and post-move costs could have derailed the deal.
Technical survey

Before the preliminary contract we insisted on an independent technical handover. Defects were listed; the seller disputed the report. Outcome: an annex requiring fixes (~PLN 15,000 of work per the survey) instead of a large price cut.
Mortgage and paperwork
Ambiguous contract wording could have triggered a bank refusal. Early notary and branch-head meetings clarified the deal before the full application. Full support: land register, deposit terms, house purchase, mortgage advice.
Outcome
Family bought the house, secured financing, and avoided repair bills after moving in.
