Of course it's disingenuous.
Obama is not Bush's "heir". Obama ran for President. He wanted it. He got it. He owns it.
Q When did the Bush Mortgage Bubble start?
A The general timeframe is it started late 2004.
From Bushs Presidents Working Group on Financial Markets October 2008
The Presidents Working Groups March policy statement acknowledged that turmoil in financial markets clearly was triggered by a dramatic weakening of underwriting standards for U.S. subprime mortgages, beginning in late 2004 and extending into 2007.
Q Why is it commonly called the subprime bubble ?
A Because the Bush Mortgage Bubble coincided with the explosive growth of Subprime mortgage and politics. Also the subprime MBS market was the first to collapse in late 2006. In 2003, 10 % of all mortgages were subprime. In 2006, 40 % were subprime. This is a 300 % increase in subprime lending. (and notice it coincides with the dates of the Bush Mortgage bubble that Bush and the Fed said)
Some 80 percent of outstanding U.S. mortgages are prime, while 14 percent are subprime and 6 percent fall into the near-prime category. These numbers, however, mask the explosive growth of nonprime mortgages. Subprime and near-prime loans shot up from 9 percent of newly originated securitized mortgages in 2001 to 40 percent in 2006"

"Another form of easing facilitated the rapid rise of mortgages that didn't require borrowers to fully document their incomes. In 2006, these low- or no-doc loans comprised 81 percent of near-prime, 55 percent of jumbo, 50 percent of subprime and 36 percent of prime securitized mortgages." (Fed link above)
Q HOLY JESUS! DID YOU JUST PROVE THAT OVER 50 % OF ALL MORTGAGES IN 2006 DIDNT REQUIRE BORROWERS TO DOCUMENT THEIR INCOME?!?!?!?
A Yes.
Q WHO THE HELL LOANS HUNDREDS OF THOUSANDS OF DOLLARS TO PEOPLE WITHOUT CHECKING THEIR INCOMES?!?!?
A Banks.
Q WHY??!?!!!?!
A Two reasons, greed and Bush's regulators let them.
Q Why would Bushs regulators let banks lower their lending standards?
A. Federal regulators at the Office of the Comptroller of the Currency (OCC) and the Office of Thrift Supervision work for Bush and he was pushing his Ownership Society programs that was a major and successful part of his re election campaign in 2004. And Bushs regulators not only let banks do this, they attacked state regulators trying to do their jobs. Bushs documented policies and statements in timeframe leading up to the start of the Bush Mortgage Bubble include (but not limited to)
Wanting 5.5 million more minority homeowners
Tells congress there is nothing wrong with GSEs
Pledging to use federal policy to increase home ownership
Routinely taking credit for the housing market
Forcing GSEs to buy more low income home loans by raising their Housing Goals
Lowering Invesntment banks capital requirements, Net Capital rule (Going from 12-1 to 35+-1 in 2004, flooded the market cheap money)
Reversing the Clinton rule that restricted GSEs purchases of subprime loans (2004)
Lowering down payment requirements to 0%
Forcing GSEs to spend an additional $440 billion in the secondary markets
Giving away 40,000 free down payments
PREEMPTING ALL STATE LAWS AGAINST PREDATORY LENDING
But the biggest policy was regulators not enforcing lending standards.
