WRT to PMI, it is not that simple
first, lenders will often offer 2nd mortgages to cover the balance on the 1st mortgage to get around the need for PMI. I did this for my first home.
second, the value of the insurance is not for the full value of the loan. The insurance only covers a small portion of the value of the loan, because the bank (in foreclosure) also receives the asset (house) so no need to insure the whole thing.
third, people were failing on their loans nearly immediately, thus not even starting to pay PMI.
An Example.
Person A buys a $500,000 house with 0 down. he gets $525,000 to cover closing costs,etc (this may be an extreme example). The value of the PMI may only be 5 or 10% of the LOAN amount, lets say $50,000
so a year goes by and the borrower is faling to make payments and the overvalued house has lost $100,000 in value. house if foreclosed
BUT it gets worse. Lender has foreclosing fees, lawyers fees, (and I may be wrong here but is responsible for any liens on the house, ie taxes, workers, etc).
but the value of the house is only $400k but the real value is what can be received in a foreclosure sale-which will further lower the price cause a. there is a glut of houses for sale AND buyers realize lenders are very eager to unload the properties cause if they DONT unload them, they are paying property taxes, insurance on these houses.
