Why your second investment loan is harder than your first

There's a familiar pattern in investor finance: the first investment loan goes through smoothly, the second one stalls. Same job, same income, sometimes more equity, and yet the bank says no. Often, the issue is not just income. It is how the first loan was structured, how the existing debt is assessed, and which lender is looking at the whole position.

Lender servicing models are cumulative. Every existing loan you have gets stress-tested at the assessment rate (typically rate + 3%), and the resulting repayment is treated as a fixed expense against your income. So by the time you apply for loan #2, your existing investment loan is being assessed as if rates were 9%+, even if your actual rate is 6%.

The lender choice on loan #1 dictates this. Some lenders are more generous on servicing: they use actual rate for existing debt, accept higher rental yield assumptions, and assess rental income, expenses and existing debt commitments differently. Some lenders may recognise negative gearing add backs where their policy allows it, but this varies materially and should not be assumed. Others are tight. Most first-time investors don't know there's a difference, and the broker who placed the first loan often wasn't thinking three loans ahead.

What to do if you're hitting the wall on loan #2: (1) Refinance loan #1 to a lender with stronger servicing; this can free up $200k+ of borrowing capacity overnight. (2) Restructure loan #1 to interest-only (lowers the assessable repayment). (3) Move loan #1 to a lender that 'sits outside' the lender you want for loan #2 (diversifies your APRA risk concentration).

Loan portfolio strategy matters more than any single rate. We sequence lenders so each loan supports the next, not blocks it. The goal isn't the cheapest rate today; it's the portfolio you can build over 10 years.
