Everything on this page is general guidance, not personalised advice. Your actual situation may differ, always confirm your specific circumstances with a qualified broker before making a decision.

Before you try the calculator below, it's worth checking exactly what's on your file, that way your result reflects your real situation, not a guess.

What's My Realistic Starting Point?

Most people have more than one thing on their file, and deposit size changes everything. This gives you a fuller, more accurate picture than a single lookup ever could.

Step 1: What's on your file? (tick all that apply)
Step 2: What deposit do you have?
15% deposit
= 85% LTV

Depending on what's on your credit file, smaller changes in deposit may not move the result here. Some lenders expect a larger deposit before they'll consider more severe cases, so this varies by situation.
