Lower Credit Card Limit = Lower Prospective Mortgage?

Question

I understand that higher credit card limits should increase your FICO score. For the sake of my question, let's assume that a minimum of that available credit is used, and a good credit history.

Why then, does TD Canada Trust's online calculator reduce one's available mortgage with an increase in credit card limit? I find that quite confusing and would really appreciate any insight that anyone might have.

Thank you in advance!

Answer 1

Most likely temporary, they had to check your credit in order to raise the rate. Just a guess went down 5-7 points?
