When you run your Product Comparison search you will be shown Rates based on the Loan Amount and LVR that you use for your search.
The above example is $1,500,000 with an LVR of 75%
You will see those same Rates displayed in the Comparison itself according to the Loan Amount and LVR in the left hand panel.
When you then select a Product and 'Apply Product to Loan' it will be added to the Products section of the Opportunity.
If the rate displayed appears to be incorrect you will need to check the Details section for the Security Total Amount and LVR displayed there as this is what the Products section is using.
In the above example, the Security amount is $1,000,000 so the effective LVR becomes 150%. If the Security field is grey then it is using entries in the A and L section. All Securities marked as 'Yes' used as Security will be totaled.
In this example the second Security needed to be marked as 'Yes' used as Security.
Now the correct 75% LVR is being used for the Rate calculation.
