A lender offers you a mortgage interest rate based upon a number of factors, but by far the most important is the secondary market for mortgages. Banks typically sell their mortgages to aggregators like Fannie Mae and Freddie Mac, which are government-sponsored enterprises that buy and repackage mortgages. Aggregators issue mortgage-backed bonds to investors in the secondary market. The daily fluctuations of supply and demand affect the interest rates investors require to buy these bonds. As the economy strengthens, investors require a higher interest rate on bonds because of growing competition for their investment dollars. Banks peg their mortgage interest rates to the daily interest rate on mortgage-backed bonds in the secondary market.
The programs vary in what they can offer. In some cases direct financial assistance may be provided to help you pay your mortgage for a short period of time. Payment plans or reduced monthly payments may be offered. However most of the government programs and non-profit organizations will help facilitate some form of loan modification to qualified homeowners. This will provide families time to get back on track by ideally lowering their monthly payment, reducing interest rates or waiving fees.
