California 15-Year Fixed Mortgages Half the time, less interest

A 15-year fixed repays the loan in half the time of a 30-year and can save a lot of interest. The catch: a bigger required payment every month, even when life gets expensive.

When it fits

Sometimes the 15-year is the clear winner. Sometimes a 30-year with extra principal gives you a safety valve. It depends on how steady your income is and how much cushion you keep.

Get my options

Good fit if

  • Steady income and a solid emergency fund
  • Refinancing and the shorter term still feels comfortable
  • You care more about total interest than monthly flexibility

Watch out for

  • The higher payment is required, even in a bad month
  • Don't drain savings to make it work
  • Compare retirement saving, other debts and cash reserves too

The program is only half the answer

We weigh the program against your whole picture: credit, income, the property, how long you'll keep the loan, cash to close, points or credits, and mortgage insurance.

The details that matter

Example: same loan, two terms

To isolate term alone, compare the same $300,000 loan at the same hypothetical rate. No fees, points, mortgage insurance or extra principal; actual pricing can differ.

15-year fixed: 6.000% interest rate · 6.000% APR · 15-year term · 20% / $75,000.00 down · 180 monthly P&I payments of $2,531.57.

30-year fixed: 6.000% interest rate · 6.000% APR · 30-year term · 20% / $75,000.00 down · 360 monthly P&I payments of $1,798.65.

Approximate full-term interest: $155,683 versus $347,515. First payment one month after a single advance; no balloon. Taxes/insurance/HOA excluded; actual housing obligation higher. Not a quote/approval; rates change daily.

  • The shorter term requires $732.92 more every month in this same disclosed example, even during an income interruption.
  • Taxes, insurance, HOA, and mortgage insurance are excluded. Compare cash reserves, repairs, retirement contributions, and other debts before committing.
  • Full-term interest assumes the loan is kept to payoff. A sale, refinance, fees, or extra payments changes the comparison.

Compare real quotes, not just equal-rate examples

Actual 15-year and 30-year rates can differ. A lower quoted 15-year rate would increase the interest advantage over this same-rate example; different fees can change it again. Compare both quotes and keep an emergency fund, rather than draining savings to force a shorter term.

  • Discuss mortgage prepayments alongside retirement saving and other debts with your financial advisor; interest savings aren't the only goal.
