Starting Out First home

[Reginald R Cloutier Jr]

Hi I'm new to this and looking for my first property. I'm actually going to check a place out over the weekend which has two properties on one lot. Needs a little work but I also want to live on one property and rent then other. I'm trying to run numbers based off info I have from listing, I will know a little more when I see it in person. But my question is in trying to run numbers because it's a mix of live and brrrr type deal? Thank you.
