https://aiobs.org/how-healthy-and-costly-are-the-most-used-i... shows insulation cost for a (typical?) 1500sqft (~140m^2 for the rest of the world) home. The most common, and also the cheapest, type of insulation being fiberglass bats at $560. So if this home would cost $200k, that's 3% of the total price. So even if asbestos would be free, it would barely move the needle in total cost.
Edit: That $560 looks suspiciously low. Googling around some more shows an insulation (incl. installation) cost for a "typical" home at around $3500-$4500. In any case, a small fraction of the total cost of a house project.
