Dividend and Interest (mortgage calculator, deduct, lenders, reduce)

[KayAnn246]

I have dividend and interest income. I've seen some mortgage calculators include this as income calculation. How and when do lenders consider this as income for mortgage purpose?
Will I only need to show brokerage statements and tax returns?

2 years tax returns and evidence the assets still exist.

If you will be using any portion of those assets for your purchase, the proportionate income will be deducted. So say you use 25% of your assets to make the purchase, the dividend and interest income will be reduced by 25%. If you are liquidating much of the assets (over 70%), that income will be heavily scrutinized.
