Lead based paint inspection waiver?

[Thuy Pham-Satrappe]

On the contract for a fixer duplex I am looking to purchase it looks like they pre-selected that I waive my opportunity for inspection of lead-based paint. Given the year it was built it seems like there is a reasonable probably that there may be some lead based paint. That being said, is it a real estate strategy to mark that box so buyers can't withdraw offer upon discovery of lead based paint upon inspection?
