Your best interest rate and most often the lowest will most likely be from a private source such as a parent or friends. However, when you borrow money from your parents or friends it is essential that you treat it as a business transaction. You should commit to making payments on time and the person who is loaning you the money agrees to not bring up the fact that they made the loan to you to others. Written terms of agreement help to eliminate any possible miscommunication between the two of you as well as establish a legally-binding contract that makes the transaction seem more real to the both of you.
Additionally, your own bank or financial institution is a great resource to consider. Often they will offer more than one loan package. Consider your options and when you have determined that you can meet the terms of the loan, get those terms documented and compare them with the offers of other financial institutions.
Loan or Finance Companies are also another great option to consider. Historically, they companies are considered as being there for high-risk clients there are a few that offer the lowest loan interest rates as well as a variety of rewards, instead of penalties, for early loan payoff. This resource may end up being your best bet in your quest for a low personal loan interest rate.
Always compare multiple possibilities from a wide array of potential loaning institutions before committing to a singular loan. When you do, you will get the best personal interest rate you can.
