How long will you own the property for?

What other costs will be involved in purchasing and maintaining the property?  Will the investment income cover those costs and the interest repayments"

Can I negatively gearing my loan so that the interest I pay is greater than the income I receive from my investment?

How will this loan impact on my taxable income? 

How much are you relying on the profit from this investment?

Should I take a principal and interest loan (paying back the loan amount and the interest) or should I look at paying interest only and pay the loan amount back when I sell the property?
