House prices will keep falling in the areas where prices are still dangerously high compared to incomes and rents. Banks say a safe mortgage is a maximum of 3 times the buyer's annual income with 20% downpayment. Landlords say a safe price is a maximum of 15 times the house's annual rent. Yet in affluent areas, both those safety rules are still being violated and there is still a huge housing bubble. Buyers are still borrowing 6 times their income and putting only 3% down, and sellers are still asking 30 times annual rent, even after recent price declines. Renting is a cash business that proves what people can really pay based on their salary, not how much they can borrow. Salaries and rents prove that those high prices will keep falling for a long time. Anyone who bought a "bargain" in those areas last year is already sitting on a very painful loss.
On the other hand, prices in some poor neighborhoods have now fallen well below the cost of renting. In those housing markets, gross rents exceed 10% of the price of a house. Housing prices could still fall more if unemployment rises or interest rates go up, but on a month-to-month basis, the buyer of a very cheap house wins. So the housing market is split.
It's usually still much cheaper to rent than to own the same size and quality house, in the same school district. On rich neighborhoods, annual rents are 2.5% of purchase price while mortgage rates are 5%, so it costs twice as much to borrow the money as it does to borrow the house. Renters win and owners lose! Worse, total owner costs including taxes, maintenance, and insurance come to about 9% of purchase price, which is more than three times the cost of renting and wipes out any income tax benefit.
The only true sign of a bottom is a price low enough so that you could rent out the house and make a profit. Then you'll know it's safe to buy for yourself because then rent could cover the mortgage and all expenses if necessary, eliminating most of your risk.
