Planning ahead and keeping the future in sight is important for investors that are getting caught up with interest rates, said Mortgage Choice spokesperson Belinda Williamson.

"With much attention placed on lenders' home loan interest rates, it is easy to lose sight of the bigger picture and to neglect to factor in other loan aspects that may offer longer-term benefits to borrowers than a loan with simply the lowest interest rate,” Ms Williamson said.

"Investors should do their finances a favour by choosing a home loan on more than interest rate alone.

“A loan's features, such as an offset account or redraw facility, associated fees, and whether you choose a fixed, variable or split interest rate will have an effect on how much you will pay in overall interest and how long it could take to repay the loan,” she said.

Additional features that give investors the flexibility to continue borrowing are an important part of financing a property portfolio.

“When looking to make multiple property purchases, the flexibility of a loan product can be more important than its interest rate,” Resi Home Loans chief executive Lisa Montgomery told Smart Property Investment.

“The flexibility of a product is the key to leveraging for that next property,” Ms Montgomery said.
