You are simplifying too much. Interest rates are only one portion of the housing market in total. Like everything it is supply and demand. Housing prices drop when there is a large amount of houses available and few buyers. Interest rates only effect demand, and not supply. Most likely interest rates will remain low as long as the housing market is weak. Many factors go into whether or not someone wants to buy a house, and interest rates are only one factor.
Why would interest rates not affect supply? Some people aren't even bothering to sell right now because they can't get enough to break even. Supply in housing is derived from who is actually selling. If sellers leave the market because interest rates rise and buyers decrease, this obviously affects supply.
If they can't break even now with prices what they are and interest rates what they are, they are not going to break even in a year or two when houses are 10% cheaper and interest rates begin to go up. Foreclosures will still happen, which will add to supply. People will still move for work or retirement, which will still add to supply. Interest rates going up will have very little effect on how many people are buying houses because there are so few buying now. Interest rates will not go up until housing prices begin to rise which will drive buyers into the market. One reason there are so few buyers now is that housing prices are still dropping. It is a bad investment to buy a house now that in two years will be worth 10% less. Buying a house now will immediately put you underwater in the first month.
Personally, I am waiting for the market to hit bottom before I buy a house. Every month I save a little more and my potential future house gets cheaper, so my future mortgage continuously gets cheaper every month. I will not buy a house until that trend reverses itself.
