Buying a Four Bedroom Home: What Not to Do With Your Loan

Buying a four bedroom home in Kariong goes more smoothly when you sort out your loan structure before you fall for a house. A bigger home means a bigger loan, so small choices about repayments, rates and deposit can add up to thousands of dollars.

If you are juggling school runs, work and open homes, it helps to have someone steady in your corner. Here are the mistakes we see most often with larger family purchases on the Coast, and how to sidestep each one.

How Much Can You Borrow for a Four Bedroom Home?

Your borrowing capacity is the maximum a lender will let you borrow based on your income, expenses, debts and deposit. It varies from lender to lender, so one bank's answer is not the final word.

A common mistake is searching by price first and checking capacity later. Lenders assess your living costs, credit card limits and other debts, so a card limit you never use can still reduce what you can borrow. Checking this early tells you which Kariong homes are realistic before you get attached to one.

A broker can compare home loans from the lenders on their panel. That makes it easier to find the lender whose rules suit your situation, rather than hoping your own bank does.

Variable, Fixed or Split Rate: Which Suits a Larger Loan?

A variable rate can move up or down over time, a fixed rate stays the same for a set period, and a split rate divides your loan between the two. The right mix depends on how much repayment certainty you need and how much flexibility you want.

Each option has a trade-off. Variable loans usually allow extra repayments and offset accounts, but your repayments can rise if rates do. Fixed loans give certainty, but extra repayments are often capped and breaking the loan early can trigger costs. A split loan gives you a bit of both, but you need to manage two balances.

If your budget is tight, certainty on part of the loan can let you sleep better. If you expect to receive a bonus or sell another asset, the variable portion lets you put that money to work. Compare the features on offer, not only the headline rate, because fees and rate discounts differ between lenders. Our home loans page outlines the main products.

Interest Only vs Principal and Interest: A Worked Example

Interest only repayments are lower at first, but you are not paying down the loan, and the repayments jump once the period ends. Principal and interest repayments cost more each month but reduce the balance from day one.

Consider a family buying a four bedroom home who borrow $700,000. We will use an illustrative rate of 6.75% p.a. for both options, which is not a current offer.

On a 30 year principal and interest loan, repayments come to about $4,540 a month. On interest only for the first five years, repayments are about $3,938 a month, which is roughly $600 less. The family is tempted by the lower amount.

After five years, though, the balance is still $700,000 and only 25 years remain. At the same illustrative rate, principal and interest repayments rise to about $4,837 a month. That is nearly $300 a month more than the 30 year loan would have cost, and they have not reduced the debt in the meantime.

The outcome: the family chooses principal and interest and uses a linked offset account to keep some flexibility. Interest only can still suit some buyers, such as investors, but for an owner occupied home loan the higher repayment after the period ends needs to be planned for.

What Does a Mortgage Offset Account Actually Do?

An offset account is a transaction account linked to your loan, and the balance in it reduces the amount you pay interest on. It lets you keep savings accessible while cutting your interest cost.

Using the same illustrative 6.75% rate, $50,000 sitting in an offset against a $700,000 loan means interest is charged as if you owed $650,000. In the first month, that is roughly $280 less interest. Your actual saving depends on your balance and your loan.

The trade-off is cost. Loans with a full offset can carry a higher rate or an annual package fee, so it only pays off if you keep a meaningful balance in the account. If your savings are small, a loan without an offset may cost you less.

Why Home Loan Pre-Approval Comes Before the Open Homes

Home loan pre-approval is a lender's conditional indication of how much it is willing to lend you, and it lets you make offers with more confidence. It is not a final approval, because the lender still needs to assess the property and confirm your details.

Pre-approval usually has an expiry date, and your circumstances can change in that time. A new car loan, a job change or a higher credit card limit can all alter the outcome. Avoid taking on new debt between pre-approval and settlement, and tell your broker about any changes straight away.

If this is your first purchase, our first home buyers page covers what extra support may be available. Rules on grants and duty concessions depend on your circumstances and change over time, so confirm them with Revenue NSW before you commit.

Lenders Mortgage Insurance When Your Deposit Is Under 20%

Lenders Mortgage Insurance (LMI) is a one-off cost that may apply when your deposit is small compared with the property value. It protects the lender, not you, and the cost depends on your loan to value ratio (LVR) and your lender.

The main risk is that the premium can be added to your loan, which means you pay interest on it. Some buyers reduce or avoid LMI by waiting to save a larger deposit, but that means more time paying rent while prices and rates may move. Whether to wait or buy sooner is worth running through with a broker using your own figures.
