I do pretty decent for my age, and I live at home still, so I've been saving up a lot of money.

Then I plan to become a travel nurse and we will live in the RV while the two are being rented out and go from there buying more properties.

I am considering living in one of the units myself.

If you live in your short-term rental (STR) property in a future year after claiming depreciation, depreciation recapture does not occur immediately.

I pull permits for removal of load bearing walls, addition of bathrooms or bedrooms, addition of footage.

What do you think of my essentially 7-word answer? "It's like selling pizza by the slice".  Too simple? Just right? How would have you answered? 

The company I currently use for my other investment homes said they don't offer management for any co living... unless everyone in the home is on one lease.

Yea, the guide is a living document that I've updated several times throughout the years.

What zoning code could I request a zoning variance or rezoning that would allow us to have the 2 livable units on parcel, one primary residence and one additional living unit (known currently as ADU)?

My wife and I have one rental unit and are trying to move toward our next property, but still are trying to learn more and find additional ways to make some side income to speed the process.
