Get a Decision in Principle with Trinity Financial
Looking to understand how much you could borrow? At Trinity Financial, we make it easy to take the first step toward your new home with a Decision in Principle (DIP)—quick, simple, and commitment-free.
Why Get a Decision in Principle?
A Decision in Principle (also known as an Agreement in Principle or Mortgage in Principle) gives you an estimate of what you could borrow from a lender, based on basic financial information. It shows sellers and estate agents that you're a serious buyer and strengthens your negotiating position.
At Trinity Financial, we’ll guide you through the process and help you secure a DIP tailored to your circumstances—whether you're buying your first home, moving, or investing.

Getting a Decision in Principle (DIP) typically takes:
-
Within a few hours if you're working with a mortgage broker like Trinity Financial, assuming you provide all the necessary information upfront.

Same day in most cases, especially if your situation is straightforward.

A few minutes if using some online tools from lenders—but these are often generic and may not reflect what you can actually borrow through a broker.
