Your loan still qualifies at the full note rate. The Year 1 and Year 2 payments above are temporarily reduced by a subsidy — they do not change how your loan is underwritten. Lenders evaluate your ability to repay based on the Year 3+ payment shown above, not the reduced early payments.
This calculator provides an illustrative example only, based on the figures you enter. It is not a Loan Estimate, a rate quote, or a commitment to lend. Actual rates, payments, terms, and costs depend on a complete application, credit approval, and underwriting, and will vary by loan program.
