Two families in a single family home?

[Monica Davies]

I'm wanting to house hack, but I have a little family, so I need my own space, and the multi-family in my area are too expensive to cash flow right now.

I'm thinking of getting a single family home, with a mother in law apartment with a separate entrance, living in the basement, but eventually renting it to two families as an unofficial duplex.

Are there any cons to this, other than paying by own utilities?
