Ideally I would like to purchase a apartment condo (1000 sq foot) in the Mountain View Sunnyvale area and pay additional money instead of paying rent and building zero asset.

On the other hand, you and I both know that this will lead to a TON of calls/complaints/negative posts on social media about a disagreement of whether a previous building professional should fix something for the new owner once out of warranty, not the contractor’s fault to begin with, etc.

I have 2 small commercial office buildings in one LLC with multiple partners including myself. 

I'll see if I can post of the current build.

It doesn't look like you would be getting much from the sec121 exclusion.Not sure how selling this property would get your more funds into your Roth IRA, unless it just because it frees up money to make the contribution..If you need funds to build up a reserve / rain day fund / etc., this might be a way to go... 

Once I purchase my new home in GA, I’m wanting to keep buying more rentals and start building a portfolio, just not too sure yet on what approach to take.

I can send you a list of contacts in Ohio to help you build your team, property manager.

At $200+ a sqft plus a year of construction loans, I'm uncertain building in Phoenix area is a project I want to take on. 

What type of content or advice do you share to build credibility?

Oh, also, I think paying for all of the utilities and building that into the cost is better as well.
