My wife and I are on the sidelines because we started a family.

I'd start by telling them you'd like to rezone to multi-family at 20 units per acres and see what planning says. 

I’ve been listening to bigger pockets on Spotify for a few months and I would love to find a multi family to buy.

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.

I have some family there that is planning to jump in the venture with me.

I'd even recommend looking up on public records of some beat up small family in the area and calling them personally to see if they would sell you their property that needs work, especially if they owned it over 10 year, that usually means they are tired of it, and investing in bigger projects.

I can only say that from our 100s of clients in your situation who are helping family in India and Pakistan own in the US, it widely depends what rules and regulations to follow based on your facts and circumstances.

Often it is based on how well you pay back history.
