Business debt alone has never stopped a borrower from qualifying for an investment property loan.
What lenders actually focus on is serviceability, not the size of your business debt. They'll take your business income, deduct your business loan repayments, factor in your personal income and expenses, and then determine what's left over to cover a new investment loan. The debt itself is largely irrelevant if the numbers still stack up.
Most lenders use a serviceability buffer of around six percent of the new loan amount. On a $600,000 investment loan, that's roughly $36,000 per year, or around $700 per week, that needs to remain after all existing commitments are accounted for. Hit that threshold with the right lender, and business debt typically won't be the obstacle you thought it was.
The complication for business owners is how income gets assessed. Because business income is less predictable than a salary, many lenders may use a two-year average rather than your most recent figures, which can sometimes reduce the income figure they'll work with. Choosing a lender with more favourable treatment of business income can potentially make a meaningful difference to your assessed borrowing capacity.
The key distinction worth understanding is that business debt doesn't disqualify you, insufficient serviceability does. These are two very different problems with very different solutions, and many business owners with significant debt are still well-positioned to purchase investment property once their numbers are properly assessed.
