The Obama administration is engaged in a broad push to make more home loans available to people with weaker credit, an effort that officials say will help power the economic recovery but that skeptics say could open the door to the risky lending that caused the housing crash in the first place.

President Obama's economic advisers and outside experts say the nation's much-celebrated housing rebound is leaving too many people behind, including young people looking to buy their first homes and individuals with credit records weakened by the recession.

In response, administration officials say they are working to get banks to lend to a wider range of borrowers by taking advantage of taxpayer-backed programs — including those offered by the Federal Housing Administration — that insure home loans against default.

Housing officials are urging the Justice Department to provide assurances to banks, which have become increasingly cautious, that they will not face legal or financial recriminations if they make loans to riskier borrowers who meet government standards but later default.

Thanks largely to the U.S. Federal Reserve, Jeffrey Nelson was able to put up a shotgun as down payment on a car.

Money was tight last year for the school-bus driver and neighborhood constable in Jasper, Alabama, a beaten-down town of 14,000 people. One car had already been repossessed. Medical bills were piling up.

And still, though Nelson's credit history was an unhappy one, local car dealer Maloy Chrysler Dodge Jeep had no problem arranging a $10,294 loan from Wall Street-backed subprime lender Exeter Finance Corp so Nelson and his wife could buy a charcoal gray 2007 Suzuki Grand Vitara.

All the Nelsons had to do was cover the $1,000 down payment. For most of that amount, Maloy accepted Jeffrey's 12-gauge Mossberg & Sons shotgun, valued at about $700 online.
