What prevents interest rates from rising?
To protect yourself from an increase in interest rates get a fixed rate loan. The loan terms: interest rate, number of payments, monthly payments will be fixed for the loan. Of course if rate for the rest of the market drops during the period of the loan, you may be able to refinance the loan. But if you can't refinance, or won't refinance, the drop in rates for the rest of the market doesn't help you. If you want to be able to have your rate float you can get a variable rate loan. Of course it can float up, or it can float down. So you take that risk. Because of that risk adjustable rate loans start at a lower rate. If the market interest rate drops far enough many people will refinance into a fixed rate loan at a lower rate than they could have gotten at the start. For adjustable rate loans the lender, during the application process, details how the rate is determined. It is pegged to be x% above some national or international interest rate that they don't have any control over. If that base rate moves then your loan rate may move. They also specify how often it will adjust, and the maximum it can adjust between each adjustments and over the entire life of the loan.  That rate that starts initially lower than the fixed rate loan is the enticement that many people have to pick an adjustable rate loan. Some do it because they believe they will payoff the loan before the rates get too high, or they will see enough increase in income so they can afford the higher monthly payment if rates rise. If they are wrong about these things they may find themselves in trouble. The terms of the adjustable rate loan still have to follow the terms of the contract: the lender can't change the % offset or the source used to used to set interest rate.
