The term you are looking for is non-recourse loans. Its available the world over but seldom in retail mortgage market. The US does it but not Singapore and many others.
Its not only those who were unable to make payments that abandoned their properties. There were those who handed it back to the bank and picking another similar or even bigger property when it bottomed out. These were usually business people who are able to repair their credit at an appropropriate and "convenient" time.
In the US, one has to remove all semblence of the commonwealth system to play the property market.
There are couple of features of the property market in the US that differs from us and those that offer recourse loans such as most countries.
- property asset is a much smaller part of a family asset portfolio.
- you will see people in the 25 to 55 age group relocate often usually every 3 years
- happy to take 2nd and 3rd mortgage on the same home.
- relocating from state to state
- very small downpayment or smaller equity which ties in with multiple mortgages so that they can abandon it when it turns south.
However the usual adages do apply
- worst house in the best street
- pay for land and not the house
The best position is to acquire quality property in the Eastern states but stay in the west for a great lifestyle. California is where the 1st downturn always begins.
Most Singaporeans migrating to the US tend to buy a huge property even though their income is much lesser than their neignbours. It also happens to other migrants as well. Eeventually they will change.
I am surprised to see banks in the United States are not pursuing every legal avenue available to claim for losses incurred after disposition of assets following a foreclosure sale. That is most probably the difference right there as the banks in Singapore will not cease action upon property repossession should monies still be owed after auction.
