I am leaning towards remodeling since it would be my primary residence initially and perhaps I won’t get much return on my investment but maybe just sell it to family/friends instead… well, time to find a contractor!

Is it a good place to invest in multi family?

You don't want to narrow your buyer pool when you sell your house in future just because they might don't want the ADU but decent size backyard is always good and has its potential.If I were you, I would rather try to find deal in hayward/union city/san leandro single family house.

Exempt in Miami-Dade are single-family homes, duplexes, and buildings with a capacity of 10 or fewer occupants that are 2,000 square feet or less." 

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 4) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 5) this is related to the value added by the ADU, 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 a hand full on single family rentals in FL and live in CA.Any recommendations would be appreciated!

We never made an offer - a family friend approached us looking for help because they know we are investors.

My first investment was a condo, and I wish that I would have either waited to save up more or taken on a project to buy a single family home.

Does one post on BP, social media, friends and family, personal business connections?

If you open this as a single-member LLC, it gets a little tricky with additional state taxes when sold or if something were to happen to the single member and the property went to a family member.
