DH would be sole applicant for a mortgage as I am not employed. However, I do have income from disability benefits and from other sources (from trading on financial markets) and pay £1500 into the joint account each month from other accounts. I will keep doing this when a mortgage is granted as my independent monthly 'income' will continue to be around £2,500 per month.
How can my income best be used to contribute to DH's/family monthly income wrt calculating how much can be borrowed given that DH will need to apply as sole applicant as I don't have an employer and am not classed as self employed?
