A 4.5% example behaves like a lower-rate case for a 30-year loan. It is the lowest of the three illustrative rates on this site, not a live offer or a prediction.

If you are moving from a starter home to a broader market segment, this case gives a clean lower-rate baseline. It is useful for comparing monthly comfort against better school zones or shorter commutes.

Illustrative fixed-rate example, not a current offer or an affordability assessment. Monthly principal and interest only; excludes taxes, insurance and fees. The example above stays fixed when you edit the calculator below.
