Agreed with Adey, you'd be better trying to consolidate your loans into the mortgage or leave them as they are for now. Every time you apply for credit it registers a credit search on your file. If many searches appear on your file, this can decrease your credit score.

I'd recommend just working out a budget for yourself, including the mortgage payments, to help eradicate the debt asap. Or if you really want a consolidation loan, you could apply for it after mortgage completion.

Best of luck
