A past credit problem rarely closes the door.
Many lenders will consider an application with defaults or missed payments on file. What changes is which lenders, how much deposit you need and the rate you are offered.
Every lender asks the same questions: what happened, when, how much it was for, whether it has been settled, and how you have managed credit since. A small default from four years ago that has been paid off is a very different picture from a recent one that is still outstanding, and lenders treat them very differently.
