I agree that Mello Roos is local government and developer collusion to extract more money out of home buyers.
There should be a taxpayer revolt against it and do away with Mello Roos completely. That way builders will have to charge more for the houses. If buyers don’t buy, then builders have to cut the prices. It’s that simple. As a buyer, it works out to be the same. Either you pay with the mortgage or through Mello Roos tax.
Mello Roos is a hidden tax that few buyers paid attention to when house were appriciating at double digit. Now they feel the real pain.
