These have no fixed repayment date, although you’ll have to agree to pay the money back within a certain period, most commonly a year. Within that period, you can decide how much to pay off and when you’ll pay it. The loan can be repaid whenever your funds become available without an early repayment charge, for instance, when your house sells or your inheritance probate clears. These tend to charge higher interest rates because they are riskier for the lender.
