Looking to purchase second property, need advice on different loan/financing options

[Chris Huang]

Hello! I am looking for some advice here. I currently have a MF in Massachusetts and I am ready to purchase my second property (SFH). Ideally, I'd like to rent the multi family unit I own, while living in the SFH. What are some different loan options I could use as I do not have enough for 20% down. I believe because I already have a mortgage on the MF it'll impact my debt to income ratio thus making it harder for me to get a mortgage on the SFH, but is there a way to communicate to lenders that I want to use the 'rent' to help pay for mortgage? Any thoughts here? Thank you
