Loss makes me feel vulnerable. I've had my share, less than so many though, but enough to feel empathy. It's tough and I see it so much on Earth, too much suffering. The loss of free will I find unacceptable - what most of us refer to as rights.
Now, suppose that a homeowner puts down only 3% of their own money or 3. 5% for the FHA. That means if prices go down by only 3%, the house will be in negative equity and it would pay the homeowner just to walk away and say, "The house now is worth less than the mortgage I owe. I think I'm just going to move out and buy a cheaper house. " So it's very risky when you have only a 3% or 3. 5% equity for the loan. The bank really isn't left with much cushion as collateral.
