Not privy to the exact details of the act but the article says the Obama administration adopted it last week.
I found this in another article:
http://themortgagereports.com/17092/fha-mortgage-insurance-premiums-mip-change-2015
Obama made this recent change to offset the jump interest rates
As noted, FHA premium have gone up (somewhat dramatically) in recent years
I do find this claim to be dubious: "Fewer loans have gone bad and, because of a change in how the FHA cancels MIP"
Not only did this change happen recently so would be very hard to measure its effect (FHA premium can now never be cancelled where it used to drop off at a certain point in time, depending on LTV) but it just doesn't make any sense at face value. It's like saying having fire insurance has prevented more fires from happening.
Anyway, my point is that Trumps first move as POTUS is to harm first time home buyers and/or low income borrowers
I expect much more if this type in future policies
