Debt to income ratio

[Tevin Swain]

Good evening , I am new to investing and my goal is to take control of my own finances and improve my financial health. I understand that this takes time and discipline which is fine . There are two things I have questions about and I was looking for help toget answers these questions. What exactly is debt to income ratio , does this only apply to credit ? Or is this a term used for financial health? In regards to debt to income ration , what do banks and mortgage lenders look for and what is most important when presenting financial information? Ok... that is definitely more tha two questions but any question that BP can answer would be great!! Thanks in Advance!
