Hello all, I have been planning of taking a mortgage loan and in this perspective I have been getting the necessary information. What are the necessary requirements that are required to get qualified for a mortgage?

that's a very broad question.... good credit, enough income compared to debt, enough down payment, enough reserves

Your credit score at the time of application.The amount of debt you're currently carrying.Your income, relative to the amount you want to borrow.The size of the down payment you can make.
