Even with prepayments, many interest-only mortgage rate lenders will still let you pay up to 20% of your loan balance during any 12 month period without prepayment penalties. This flexibility of interest-only mortgage rates gives homebuyers more incentives in taking an interest-only mortgage rate. Interest-only mortgage rate also reduces the income you need to have in order to qualify for a loan. Looking for a home mortgage usually involves you, your money, and a bank officer or a mortgage broker. So what's the big deal? You ask. The end result is the same - you get a mortgage; you get a new house. But these two job types are different and it is important that you at least understand that difference. Although mortgage rates have the tendency to move in the same direction as interest rates, their actual movements are also based on the supply and demand for mortgages. Mortgage rates have a slightly different equation in their supply and demand as compared to interest rates. This is the reason why sometimes, mortgage rates move differently from other rates. With adjustable-rate mortgage payments, there is little chance of you knowing what your future monthly payment would be. Some types of adjustable-rate mortgage payments have limits to the interest-rate increase. When an adjustable-rate mortgage reaches a certain percentage, the interest rate will no longer increase for the duration of that period. Reducing even a fraction of your mortgage interest rates can save you a great deal of money on your mortgage. The rise and fall of mortgage interest rates have become erratic during the past 20 years. As a rule of thumb, mortgage interest rates go up when the economy is strong and stock prices rise. On the other hand, if economy weakens, mortgage interest rates go down.
