When European Buyers Use Lizaz Invest
- Before paying a deposit (Kapora) or signing a notary promise-to-sell on a plot in Kocaeli or Sakarya.
- When comparing two industrial OSB or logistics parcels whose m² asking prices hide major earthwork or infrastructure differences.
- When overseas heirs or diaspora families want to evaluate the real buildable envelope of family-owned land in Türkiye.
Independence & Regulatory Scope

Why Price per m² Misleads Overseas Land Buyers in Türkiye
Online property portals frequently advertise rural or agricultural land in Sapanca, Kartepe, Kandıra or Karasu as “villa land” without disclosing watershed protection zones (İSU/SASKİ), Law 5403 soil-protection restrictions or missing cadastral road frontage.
Similarly, industrial plots outside Organized Industrial Zones (OSBs) can require costly highway access permits, retaining structures or transformer installations that erase an apparent purchase discount.
