In addition to over 30 business-related transactions, I've completed 3 personal residence transactions.

Single family residence in Los Angeles (built in 1962) has only 1 covered parking spot, and a second cannot be added.Do I have to comply with current parking requirements (2 spots) to add a detached accessory structure for storage etc. 

If the inspection results indicate no major fixes are needed, it will have that going for it, plus it's located in a low crime area, and the target tenant for this kind of residence is less likely to trash the place (B+ neighborhood). 

He's not looking for an investment, just a primary residence. 

I bought their house as my primary residence.

Citizenship and residency become an issue for non-us tax paying entities. 

After reading so many stories of success here on the site and really thinking pretty heavily on my future I had moved to the conclusion of renting out the home rather than “house-hacking” or making the home my primary residence.

As well as a certain percentage I’d like my personal residence paid down to.

If the rent is fair market value, and it is primariry residence of your daughter, it is an investment property for you and thus qualify for 1031. 

The regulations are basically 1) You must be the permanent resident of the unit you wish to rent, 2) You must be registered with the City as a business and as a short-term rental, and 3) You may only rent 90 unhosted nights per year.
