This depends on your deposit as the more deposit you have the higher the income multiple. You could get up to 4 times joint income from one company but the norm is 3.75 - 4 times the first plus 1 - 1.5 times the second. As you have similar incomes then the alternative multiplier that companies use of 2.75 - 3 times your joint income will be better, i.e. �129,000. As I said though it depends on your deposit.
