Roll high-rate debts into your mortgage.
Moving high-interest debt into your mortgage can lower your monthly payment; lifetime interest may increase. The debt is then secured by your home and spread over a longer time.

The default rate is an illustrative modelling input as of October 2026, not a quote. Enter your actual refinance rate.
Lifetime estimates assume unchanged rates and fixed monthly payments until payoff. Refinance costs are added to the debt portion; the existing mortgage is excluded.

Lower payment, longer runway — model the lifetime cost
Consolidating works because mortgage money is cheap relative to credit cards and unsecured lines. Swapping 19.99% revolving debt for a sub-5% mortgage rate can slash the interest you pay each year and free up real monthly cashflow — the before/after bars above show exactly how much.
The trade-off no one mentions
The catch is amortization. A balance you might have cleared in two or three years now rides on a 25-year mortgage. Even at a far lower rate, stretching it that long can mean more total interest on that slice over its life. That’s why the donut above models lifetime cost, not just the monthly drop — the smart play is often to consolidate for the cashflow relief, then apply prepayment privileges to clear the consolidated portion fast.
Two guardrails we put on every file: keep the new financing under 80% of your home’s value, and close or reduce the unsecured limits you just paid off so the debt doesn’t rebuild. If you don’t have the equity to refinance, a HELOC or a full refinance comparison is the next step.
