Are parents a househack?

[Parteek G.]

I am currently purchasing a house and my parents are going to live with me. The mortgage will be ~$1,700 and they will be paying me $1,300 monthly. How can I leverage this situation to buy my first rental property? Reporting this $1,300 income on my taxes can help me increase my income. Also, I can show a portfolio lender that I am only paying $400 mortgage which can help me get a loan even if my DTI is off. Am I on the right path or thinking this correctly? Thank you so much in advance.
