Good debt, unlike bad debt, is debt that is secured. That means it has something behind it, something that if you cannot repay the debt, can cover the amount. Lenders like good debt as they know if anything happens they are safe. So they will offer you a lower rate on the debt, as it is safe it is not bad debt. It is good for you because it makes you look like a sensible borrower, which will be reflected in your future affairs. The lenders can then use this good debt to make more money and lend to other lenders so good debt makes the financial world go round.
Bad debt is just the opposite; it is debt that has no security. Security is collateral, like a house or a job, but a bad debt is not backed by anything. This means it has a much higher rate and cannot be traded. It also means you look like a bad borrower, because an unhealthy deal is always the last option. It reflects someone who cannot control their spending, who does not have collateral and equity and does not have control of their finances.
Bad debt can be credit cards or it can unsecured loans. It can be excessive phone bills and it could be store cards. All these things can be procured without a house and without a job, so they ook bad on any future scores.
Bad debt gives you a bad name. Because it is unsecured, and detrimental to your future finances, it is noted and used when it comes to future decisions. A lender will look to your credit score and notice when you had bad loans and how you managed them. This means bad debt affects good debt.
The simple way to control your bad debt and your good debt is to talk to a financial adviser. A financial adviser will immediately spot what responsibilities are hindering you and which ones will help your future. It might be a lot of work weaning yourself off of bad debt, but its crucial in securing good debt and a good financial future.
