That’s what I found after researching as well. Now on the opposite side of the spectrum, we bought a house with zero insulation in the attic. Paid $1800 for I think 16" of blown in insulation. Simple return on that was less than 6 months. Next will be crawl space insulation and encapsulation. That’s going to run around $3000 and I expect maybe 2-3 year return on that.

Hah, did the same. I removed all of the old insulation too, which was worse! Sealed cracks and holes, then blew in new loose fiberglass up to R-60.
