For two years now we’ve been hearing that the refi boom won’t last. And guess what? It’s lasted. In fact, it’s lasted so well that this year mortgage bankers will fund $1.7 trillion in loans compared to $1.4 trillion in 2011. Lenders are happy and vendors are happy. There are many regulatory changes looming on the horizon but one of the most important (to smaller players) is the possibility of higher net worth standards coming from Fannie Mae and Freddie Mac, and maybe GNMA. We know lenders are making good money in 2012 so now is the time to ask: are they putting enough money away for a rainy day – money that can be used to bolster their net worth position?
