Can I make a low down payment without having to pay private mortgage insurance (PMI)? The Alliant Advantage Mortgage (AAM) program allows qualified homebuyers to make a low down payment without pricey PMI payments. First-time homebuyers: as low as 0% down payment on loan amounts up to $650,000 and a variety of ARM term options available. Non-first-time homebuyers: as low as 5% down payment (or refinance with 5% equity)
