Consolidation moves higher-interest balances into a mortgage secured against your home. Monthly obligations usually fall. Whether the total cost falls is a separate question — and the more important one.
Run the comparison properly
- List every balance, its interest rate, and its minimum payment
- Calculate roughly what the current path costs in total interest if nothing changes
- Calculate the new mortgage payment, and the total interest over its amortisation
- Add every transaction cost: penalty, appraisal, legal, discharge, lender and brokerage fees
- Compare total cost to total cost, not payment to payment
A lower payment is not automatically a saving
The structural change matters too
Unsecured debt becomes debt secured against your home. That generally lowers the interest rate, and it also means the consequences of falling behind are much more serious. This trade should be made deliberately, not incidentally.
The question nobody enjoys
If the balances accumulated because monthly income does not cover monthly expenses, consolidation clears the cards without addressing the cause. Many households consolidate, rebuild the balances within two years, and end up with both the mortgage and the cards.
Consolidation works best when something specific has changed — a one-off event has passed, income has increased, or a concrete budgeting plan is in place alongside it.
Two structures to compare
| Refinance the first mortgage | Add a second charge |
|---|---|
| One payment, one lender | Two payments, two lenders |
| May trigger a prepayment penalty | Leaves the existing mortgage untouched |
| New rate applies to the entire balance | Higher rate applies only to the new portion |
| Usually a longer term | Usually a shorter term |
