Calculating DTI for STR

[Kevin Murray]

Greetings all. Scouring the internet for answers to this question but haven't found anything definitive. I'm looking to purchase a property for STR and do not own the home I live in. I rent a home and have never before purchased a home.

Is my rent for the home I live in included in my DTI?

Would there be any possibility of a lender including any revenue from the STR in my projected income?

Any help from the community would be very much appreciated!
