Key Insight: Choosing the Right Option
The lowest monthly payment isn't always the best choice. A 15-year mortgage costs more per month but saves dramatically on total interest. A 20% down payment eliminates PMI and often qualifies for a lower rate — but requires more upfront cash. Use this comparison to see which trade-off fits your situation.
