two houses, one long term rental one is my personal

[Samual Armentrout]

Hey guys long story short i own one long term rental (paid off) cash flowing around $1080 a month, My second home is a 4 bedroom 3 bath house , the mortgage is $1350 and i house hack with two roommates so between the long term rental and my roommates i dont pay any for my mortgage. I also have a business which takes up alot of my debt to income ratio due to trucks and other equipment. Im wondering how i can get into more rentals and continuing growing my portfolio as i cant see that the bank or lenders will allow me to purchase anything else due to the debt to income.
