I'm not sure if they'll consider the full payment or your payment plan amount when you apply for a mortgage. That might even vary from lender to lender based on how strict their underwriting standards are. I would read up about debt-to-income ratios and how they affect the amount you can afford for your mortgage. Basically, your student loan payment will count against your "back-end" or total debt ratio. You could also visit with a lender and share your situation and see if they consider the full payment amount or the IBR amount when calculating that ratio.
Makes sense. Thanks!
