It depends on the variables. How many years do you owe, the amount that you owe, what is your current credit score, etc. The best place to start is contact your CPA (Certified Public Accountant) and your lender. If you are currently on a payment plan you need to calculate this into your DTI (debt to income ratio) and provide all documentation and billing to your CPA and lender so they know what they are working with. Many loans require that your are in good standing with the IRS to be pre-qualified, etc. Some banks will allow you to use equity in order to purchase a home even in this event, however that is not always a guarantee. Ps. I would also contact a tax attorney to help with this process. Hope this helps, and best of luck to you in your purchase.
