Most Lenders use 100% of Child Support and/or Alimony income provided that it does not exceed 30% of the total income being used to qualify. You must be able to provide copy of separation agreement and proof of receipt of funds by way of bank statements.
If you’re paying Child Support or Alimony, you must include this payment as a monthly debt obligation. Again, the lender will need to see a copy of your separation agreement or some proof that these payments are being made (ie. we’ve used cancelled cheques as proof of payment with a couple of lenders).
