The prices for mortgage-backed bonds, and by extension, the mortgage rate a lender offers, are constantly responding to economic factors. In a strong economy, the rise in inflation (i.e., the general price level of goods and services) speeds up as greater demand increases competition for financing, goods, services and labor. This drives mortgage rates higher. A slow-down or recession causes mortgage rates to fall. The U.S. stock market is considered a leading indicator of economic activity. If it tanks, demand for investment shrinks and mortgage rates drop. Conversely, rates rise when the stock market is strong. When there is high unemployment, the economy is relatively weak and mortgage rates tend to fall. If jobs are easy to find, the economy is strong, and rates rise. Like the stock market, rising foreign markets indicate a strengthening world economy and higher rates. When foreign markets tumble, it puts downward pressure on interest rates.
To be clear, you don't need a pre-approval to start looking at houses. However, since a pre-approval is essentially the same as a full mortgage approval, just without a specific home in mind, it can be an extremely valuable shopping tool. Specifically, if you submit a pre-approval along with your offer, it tells the seller that you're a serious buyer who is not likely to run into trouble when obtaining financing. One caveat: A pre-approval and pre-qualification are two different things. A pre-qualification is based solely on information you provide and is not a commitment to lend money, therefore it doesn't carry nearly as much weight.
Foreclosure mediation programs have been created by cities, counties, and state governments. A number of local court systems have also created mediation programs that will ensure lenders, banks and homeowners meet with an attorney or professional mediator to explore all solutions to a foreclosure. Learn more on foreclosure mediation programs and whether your state or local government offers one.
