I have been looking for similar data. I believe that mortgage defaults are a scapegoat for what is really happening in the financial world.
Let's just say that there are approximately 112 million households in the US (based on census data for 2008). If we assume that the home ownership rate in this country is 75% (the historical average over the last decade is much lower), then there should be about 84,000,000 people who own their home. According to a 2001 study by the Census Bureau and the Department of Housing and Urban Development (HUD), "nearly 40 percent of all residential properties in the United States, owner-occupied and rental units, are not mortgaged but are owned free and clear." This has most likely gone up over the last few years, but if this is anywhere close it leaves approximately 50,400,000 homes with some form of a mortgage on their home.
Lets assume that banks typically recover around 75% of a defaulted mortgage (remember that mortgages still have an asset backing them up, even if its value is declining). Now lets also assume that the average mortgage is $200,000 (also an aggressive number). That would mean that the $700 billion bailout proposed would allow for $50,000 per home on 14 MILLION homes.
That is 28% of all homes in America that have a mortgage associated with it. Call me crazy, but I can't see how this bailout is "really" only associated with home mortgages as is commonly espoused by the media and politicians. How many people do you know that have foreclosed and handed over their homes to the bank? Is it 28% of your friends and family?
