The Federal Home Loan Banks’ fledgling Mortgage Purchase Program doesn’t appear quite as small as it once was. In fact, MPP appears to be gaining some serious ground on the competing Mortgage Partnership Finance program this year. Through the first nine months of this year, MPP purchased or funded a healthy $10.4 billion in mortgages. That was way up from the $4.3 billion in MPP mortgage fundings from all of last year.
