IMO here's the differences between the areas you mentioned:1.

You're likely better off attending your local REI meet-up to see if you can find an investor who has house-hacked or is currently house-hacking their primary home.

Your success in this space will also translate to different type of business relationships. 

After they moved in, we started to get some mild complains from our neighbors (for the rented unit which was our primary residence until we moved out in another house a few miles away). 1.

Depending on comfort and cash, it might be a viable option as you can build equity and then sell without having capital gains, assuming it's your primary residence and you've lived there for 2 years.

I have lived in Austin for almost 20 years where I own one house that has been my primary residence for four years now. 

I've done it for two different properties and happy I didn't go FHA for that reason- although everyone's circumstances are different.

Was this a flip or a new primary? 

There are a bunch of ways to do this depending on the property type, usage, and you (income and credit scores).If this is a primary residence, you can get up to 90% of the value of your home minus any exisitng debt. 

Points I can roll into the cost and don't mind a buy down if necessary.My primary concern is the bleed rate monthly for the build, Airbnb stabilization and the year after while we season it and prep for final financing for long term hold.
