Stupid question, I know but, have you approached the bank that you originally defaulted the loan with? As they would be fully aware of your history, would they not be more inclined to offer you a mortgage? Possibly 92-95% mortgage? You could always get a loan to cover the short-fall and remortgage in 12 months to clear the loan? IMO tho think you'd be mad getting 100% mortgage at the moment anyway - interest rates are sky-rocketing at present and as stated by previous posters, your house value may not rise in line with it.
Only other option that I can think of is your partner going for the mortgage on their own - won't be offered as much tho!
