Borrowers might see a jump in their mortgages, according to Zillow.  An analysis by Zillow determined that proposed reforms to the GSEs, Fannie Mae  and Freddie Mac , may increase monthly payments by up to $400 a month.
The changes being considered by Congress are intended to reduce tax payer risk in the event of another market crash. Fannie and Freddie have been under government conservatorship since September 6, 2008 following the housing crisis. However, Zillow’s analysis shows the changes may decrease housing affordability as borrowers seek alternatives, by seeking shorter loan durations and facing higher rates.
"Some GSE reform proposals could lead to the end of the 30-year mortgage as we know it, which has long been the bedrock for financing homeownership in America," said Zillow Senior Economist Aaron Terrazas. "If monthly payments do rise and, more importantly, stay elevated, at some point we'd expect home prices to come down a bit in response to this decreased purchasing power, and some long-time owners could opt not to sell to preserve their smaller monthly payments.”
Borrowers seeking alternatives to the 30-year mortgage may face increases in their monthly rates by as much as $400 as they move from a 30-year loan to a 15-year fixed-rate mortgage. Additionally, 30-year non-conforming loans, which are not guaranteed by the GSEs, would cost borrowers around $20 more per month.
“A shorter loan period would mean the lifetime cost of the home is lower, and some households may be able to absorb the extra monthly cost on their mortgage,” said Terrazas. “But in the nearer term, first-time homebuyers or buyers on the margin could feel a real pinch as homeownership becomes significantly less affordable."
Zillow notes that until these changes are officially signed into law, there is now way to know for certain how GSE reform will impact borrowers.
