What is Mortgage?

I personally do not understand what and how mortgage works. Every time the word mortgage has been uttered, no other things put into my mind but money.

Lately, during my vacation in our farm town, I asked my mom how top mortgage deals work. She explained to me a lot of stuff and even gave examples. But I honestly failed to grasp even one. I told that to my mom.

A day or two passed by, I looked over the internet for me to read and know more about it. I just then understood that mortgage is an amount of money being loaned to finance for something. It’s about money, indeed. After which, I just lurked also about a few information on mortgage deals and how things work.
