Pulte's move to treat VantageScore on par with FICO loosens how mortgage credit is priced rather than making homes more affordable. Pulte claims it saves $1,600 per Rocket closing, yet the score fee gap is about $9; the real change is VantageScore 4.0 running up to 20 points higher. That may push home prices up. VantageScore was never tested through the financial crisis or for negative convexity, which MBS buyers must know, so they are expected to push back. x.com x.com x.comÂ
