Not sure how to navigate buying one specifically to live in. 

Rented my house we originally lived in 12 years ago because we couldn’t sell it when we moved and that’s how we got started. 5 years ago we made a plan and an effort to accumulate multi family properties and did that.

Being based in the Raleigh area and having lived in Chicago I am biased toward Raleigh area for investing. 

Since you're living in it, the worst case scenario is paying the full mortgage which hopefully you would be able to do anyway. 

However, you can use a cost segregation study to break the property into different class lives and claim more depreciation up front.

I would go with your gut on which home you would rather live in.

I originally lived in the casita while I rented the front home out.

Similarly, you can offset credits from the activity against the tax on up to $25,000 of nonpassive income after taking into account any losses allowed under this exception.If you’re married, filing a separate return, and lived apart from your spouse for the entire tax year, your special allowance can’t be more than $12,500.

What I've found so far is the property has to be self-managed for the first year and you either need to live in it 14 days or 10% of total days it was available to rent, whichever is greater.
