7 Things to Check Before Taking Out a Home Loan

A home loan is usually the largest and longest financial commitment a person ever makes. A 25-year mortgage is 300 consecutive monthly payments – three decades of your income already spoken for.

Yet most borrowers ask a lender only one question: what is the monthly payment? Lenders are glad to answer, because there is an easy way to make that number look good – stretch the term. You walk away feeling you got a deal, having quietly agreed to pay tens of thousands more.

These are the seven things worth settling before you sign, roughly in order of how much money they move.

1. The Term – The Most Expensive Number on the Page

This belongs first because it moves more money than anything else on the list. Take a $300,000 mortgage at 6% and simply change the term:

Look at the two ends. Moving from 15 years to 30 years cuts the monthly payment by $732.92 – genuinely helpful if money is tight. But total interest rises from $155,683 to $347,515. You are paying an extra $191,832 to reduce the monthly figure.

If you can service the 15-year payment, do it. If you cannot, take the longer term but treat overpayments as a priority whenever your income allows.

Term	Monthly Payment	Total Interest	Total Repaid
15 years	$2,531.57	$155,683	$455,683
20 years	$2,149.29	$215,830	$515,830
25 years	$1,932.90	$279,871	$579,871
30 years	$1,798.65	$347,515	$647,515

2. Your Deposit – Every Extra Percent Works Twice

Most lenders will finance 75% to 95% of a property’s value; the rest comes from you. The instinct is to put down as little as possible and keep cash in hand. That is usually the wrong call, because a bigger deposit helps you twice.

First, it shrinks the loan directly. Second, it lowers your loan-to-value ratio, and lenders price risk off that ratio – a lower LTV often unlocks a materially better interest rate. On a $400,000 property, moving from a 10% deposit to a 20% deposit cuts the loan by $40,000 and can drop your rate into a cheaper band at the same time.

3. How Much of Your Income Should the Payment Take?

A widely used guideline is that total debt payments – mortgage, car finance, credit cards, student loans, everything – should stay at or below about 40% of monthly take-home pay. More cautious advisors suggest 35%.

If your household takes home $6,000 a month, that puts the ceiling around $2,400 across all debts. An existing $400 car payment leaves roughly $2,000 for the mortgage, not $2,400.

• Use take-home pay after tax, not gross salary.
• Do not count bonuses or commission as though they were guaranteed.
• If you are combining two incomes, consider how the payment would look on one.
• Remember that property taxes, insurance, and maintenance sit on top of the payment itself.

4. Fixed or Variable Rate?

This is a question about your tolerance for uncertainty rather than a question with one right answer.

Fixed suits borrowers on a steady income who need certainty to budget. Variable tends to be cheaper over time and more flexible on overpayments, but only if you could absorb a rise without strain.

Ask one specific question: if rates rose by two percentage points, what would my payment become? If that number frightens you, choose fixed.

Factor	Fixed Rate	Variable Rate
Monthly payment	Predictable for the fixed period	Moves with market rates
Starting rate	Usually slightly higher	Usually slightly lower
Risk	None during the fixed term	Payment can rise
Best when	Rates are expected to rise	Rates are expected to fall
Overpayment rules	Often capped or penalized	Usually more flexible

5. The Costs That Are Not in the Interest Rate

The advertised rate is not the price. These charges sit outside it:

• Arrangement or origination fee – commonly 0.5% to 1% of the loan, often non-refundable.
• Valuation and survey fees – to confirm the property is worth what you are paying.
• Legal and conveyancing costs – unavoidable and frequently underestimated.
• Property transfer taxes or duties – often the single largest additional cost.
• Buildings insurance – typically mandatory as a condition of the loan.
• Early repayment charges – relevant if you might move or refinance.
• Late payment fees – worth knowing before you need to know.

Together these routinely add 1-2% of the purchase price. On a $300,000 loan that is $3,000 to $6,000 before you have made a single payment. When comparing lenders, ask for a full written breakdown, not just the rate.

6. Your Credit Score Sets Your Rate

Credit scoring decides which interest rate band you are offered, and on a loan this size a small difference in rate is a large difference in money.

On a $300,000 mortgage over 25 years, moving from 6% to 6.5% raises the monthly payment by roughly $95 and adds around $28,500 in total interest. That is half a percentage point.

• Pay every bill on time for at least six months before applying – payment history carries the most weight.
• Avoid multiple credit applications in the run-up; each hard search can dent your score.
• Keep credit card balances well below their limits.
• Do not close long-standing accounts – length of credit history helps you.
• Check your credit report for errors and dispute them early; corrections take time.

7. Can You Overpay, and What Does It Cost?

Overpayment is the most effective tool a borrower has, and its value is front-loaded. Because interest is charged on the outstanding balance, money paid in the early years removes interest that would otherwise have compounded across the whole remaining term.

Even modest, regular overpayments compress a mortgage noticeably. Paying one extra monthly payment per year on a 25-year loan typically clears it two to three years early and saves a substantial sum in interest.

Conclusion

A mortgage is a relationship measured in decades, so an extra hour spent on the numbers is time well spent. The single most important takeaway: do not accept the term as a default. Take the shortest one you can genuinely afford.

Before signing, get three figures in writing from every lender – the monthly payment, the total amount repayable, and a full list of fees. Compare those three, not the headline rate. The cheapest monthly payment and the cheapest mortgage are rarely the same product.

Frequently Asked Questions

How large a deposit do I need for a home loan?

Most lenders require between 5% and 25% of the property value, with better interest rates available at lower loan-to-value ratios. A larger deposit reduces both the amount borrowed and the rate you are offered, so it lowers your cost twice over.

Should I choose a 15-year or 30-year mortgage?

A 15-year term costs far less overall – on a $300,000 loan at 6%, about $155,683 in interest versus $347,515 over 30 years. Choose 15 years if you can comfortably afford the higher payment. If not, take 30 years and overpay when you can.

What percentage of my income should my mortgage payment be?

A common guideline caps all debt payments combined at around 40% of take-home pay, with some advisors recommending 35%. Remember that property taxes, insurance, and maintenance are additional costs beyond the mortgage payment itself.

Is a fixed or variable rate mortgage better?

Fixed rates give payment certainty and suit borrowers who need a predictable budget. Variable rates usually start lower and allow more flexible overpayments, but your payment can rise. Ask what your payment would be if rates rose two points, and decide from there.

Are there penalties for paying off a mortgage early?

Often yes, particularly on fixed-rate deals. Many allow overpayments up to around 10% of the balance each year and charge an early repayment fee above that. Always confirm the overpayment allowance and any penalties before you commit.
