What does a mortgage broker need when you already own rentals?

The documents a mortgage broker needs for an investment loan, when you already own rentals, answer three questions for the lender. What comes in, what goes out, and what is already owed.

Your pay comes first, then each rental's rent, costs and loan, one document for each.

Recent payslips, and often the last tax return or notice of assessment.

Each lender sets its own list, so the broker says which ones it wants.

For each rental, the lease or a recent statement from the property manager. It shows the rent and how often it is paid.

The lender reads this as income.

The council rates notice, and any strata levy notice and landlord insurance. They show what the property costs to hold each year.

The latest statement for each loan, with its balance, rate and repayment. Credit cards, car loans and a study loan count too.

Each lender counts only part of the rent, and the share differs from lender to lender. So this post quotes no share.

The broker knows how each lender it uses counts it, which is why the same records can lead to different amounts.

PropRetire's broker pack puts a household's income, living expenses, properties, other assets and loans on one dated page, each figure as recorded with its date.

It works out debt to income from them and nothing more, and it reaches the broker as a download or by secure link.
