How To Borrow Money Interest Free
There are a number of ways to borrow money interest-free if you take the time to operate the methods. However, one of the simplest ways is to borrow it from a bank which offers "overdraft protection."
You've seen those offers by banks which extend to you a loan for the amount you overdraw your checking account. By setting up two or more (and the credit limits can go up to $5000 each) you can write yourself a "loan" from one bank, cover the loan with a deposit from another bank where you have overdraft checking, and then repeat the process over a day or two.
By covering each withdrawal with another deposit, you will not be charged interest since it would take two or three days for the records to catch up - by that time, you've made another deposit which covered the original loan. Operated this way, you can keep the money interest-free for quite some time.
