How much is reasonable to pay?
What percentage(if applicable) of someone’s take home income is expected to be paid in a consumer proposal, or does it vary due to the person’s circumstances?
What if a person knows that there will be higher costs in the future (for instance, housing costs), but not in the present? Should one talk this over with a trustee?
Thank you.

The development of consumer proposal depends on several factors and can vary significantly from situation to situation. Your are best to discuss these types of things with a trustee in your local area and they will be able to help develop a reasonable proposal that will take into account both the level of debts but also the expected increases in cost of living.
