This is sort of true, unless you are putting less that 10% down on a loan. In which case, the new system rewards you with lower fees which seems counter-intuitive. So a good borrower who puts 20% down actually pays more in fees for that loan than the same borrower does who only puts 10% down who pays more than one who puts less than 5% down.
And the PMI schedule (counter to your prior statement) didn't change. In fact, its worth noting, that while the fee schedule for the loan itself was rebalanced over many more Credit score categories (going from 740 as the top threshold to 780 as the top threshold) a similar credit score adjustment wasn't made for PMI calculations.
In effect, in the prior system, the better your LTV and the better your credit, the lower your fees. Which makes common sense. In the new system, your LTV serves as a bell curve, and both extremes (High and Low LTV) get significant discounts in fees vs. the middle of the road LTVs (70-85%), And thus those who are putting down a legitimate down payment (say 20%) are subsidizing those who can't or don't.
To put it succently, an individual with a 700-719 credit score who puts down 20% on a $500K loan pays more in fees than an individual with a 660-679 credit score who puts down less than 5% on the same loan. (1.375% vs 1.25%). In what economic world does that make sense?
