We would ask to see evidence of this income via payslips and bank statements. If the income is from self-employment, we would ask to see your latest 2 years tax calculations and overviews, along with your latest bank statement.
We will accept income where it is deemed reasonable for you to work the hours in both jobs for the foreseeable future. Any hours worked in excess of this may be considered but will be weighted accordingly.
