96.7% of credit reports contain errors and around a third of those
damage your credit score to such a degree that you will likely be
refused a loan.
There are many things you can do to massively increase your credit
score in a relatively short period of time. For instance:
You should check your credit score at least every 4 months.
There are plenty of free credit score checking websites you can
do this through.
Check your credit history for mistakes, and get them corrected
- in most countries, credit agencies have to provide you with
free access to your credit information and are duty bound to correct
mistakes
Dont cancel a long term credit card - a large part of your credit
score is related to how long you have held a credit card.
