It's certainly the case that some people might argue the main advantage of money loans with no credit check is that the borrower's earlier credit history is rendered totally beside the point. All past arrears, defaults and missed payments no longer matter in the slightest. Provided a guarantor with a good credit history is found then you have access to credit again, when you could not before.
The useful idea of money loans with no credit check came about as a result of fallout from the credit crunch of recent times. Lending practices had to change allowing ordinary people with bad credit scores to access new lines of credit. The solution was the guarantor loan which has proved very popular.
With money loans with no credit check you can borrow money easily irrespective of your past credit history. If someone consents to be your guarantor, like a parent, friend or relation, you will not be credit scored, so your past credit activities need not matter.
