Should I consolidate my debts into my mortgage?

It can help cash flow, but it has a catch. Rolling high interest debts such as credit cards, personal loans and car loans into your mortgage usually lowers your total monthly repayments and the interest rate on that debt. However, stretching short term debts over a long mortgage term can mean paying more interest overall unless you keep up higher repayments. Whether it suits you depends on your situation.

Rolling your debts into your mortgage is one of the most heavily promoted ideas in lending, and it can genuinely help, but it also has a catch that is easy to miss. Here is a balanced look at debt consolidation so you can judge whether it actually helps your situation.

What debt consolidation does

Debt consolidation rolls higher interest debts, such as credit cards, personal loans and car loans, into your home loan. Because the mortgage rate is usually much lower than those debts, and the repayment is spread over the mortgage term, your total monthly repayments typically fall, which can ease cash flow pressure immediately.

The immediate benefit

The clear upside is breathing room. Replacing several high interest repayments with one lower rate repayment can free up cash each month and simplify your finances into a single payment. For someone struggling with cash flow, that relief can be real and valuable.

The catch most people miss

The catch is the term. A credit card or car loan might have been paid off in a few years, but rolled into a 30 year mortgage, that debt is now stretched over decades. Even at a lower rate, paying it over a much longer period can mean paying more interest in total, unless you make extra repayments to clear it faster.

How to keep the benefit without the cost

You can capture the cash flow relief while limiting the long term cost by continuing to pay more than the minimum, effectively paying off the consolidated debt over a shorter period within the mortgage. The discipline to keep those higher repayments is what separates a smart consolidation from an expensive one.

Address the cause too

Consolidation treats the symptom, not always the cause. If the debts built up through ongoing overspending, consolidating without changing the underlying habits can lead to the debts building again on top of the larger mortgage. It works best as part of a plan to genuinely get on top of the debt.

It is not right for everyone

Whether consolidation helps depends on your debts, your discipline and your circumstances. For some it is a sensible move that saves money and stress; for others, the long term interest cost or the risk of re accumulating debt makes it the wrong choice. It deserves a clear eyed look rather than an automatic yes.

Weigh it properly

Because the benefit and the catch both depend on your situation, the useful step is to weigh the immediate relief against the long term cost for your specific debts. A broker can model what consolidation would mean for you, usually at no cost to you, and free financial counselling is available if debt is causing stress. This is general information, not advice.

In our experienceConsolidation is a great servant and a poor master. Used with discipline to keep repayments up, it saves money and stress. Used as a way to lower repayments and carry on as before, it quietly costs a fortune over thirty years.

It usually lowers your monthly repayments and the rate on that debt, easing cash flow. But stretching short term debts over a long mortgage term can mean paying more interest overall, unless you keep up higher repayments to clear it faster.

What is the catch with debt consolidation?▾

The term. A debt that would have been paid off in a few years, rolled into a 30 year mortgage, is stretched over decades. Even at a lower rate, that can mean more total interest unless you make extra repayments.

No. It depends on your debts, discipline and circumstances. It can save money and stress for some, while for others the long term cost or the risk of re accumulating debt makes it the wrong choice.
