My reasoning is based on average historical total profits (cash flow+equity gains) LA was #1 in the nation since 2000.

I know I'll sound like a Millennial Socialist but after 25+ years of seeing it, the singular focus on profits & butt kissing at the expense of employee well being is a case study in toxicity. 

What is the best way I can profit from these properties?

@Karen YoungThe new law does not treat S-corporations any different from other types of entities, including no entity at all.There could be a tax benefit from an S-corp status if you run a highly profitable operation in flipping or wholesaling, as opposed to rentals.

While the syndicator will also benefit from selling at a profit, the person investing in this model is typically less interested in the upside profit.

Wont that impact my profits immensely?

From there I can sell after a few years for a nice profit.

I could easily walk away with 100K in profit afterwards.My issue is, if I sell it, I'm going to get hit with a tax bill unless I dump the money into a new home, correct?

If any of the variables go haywire, it could eat up your entire profit and possibly cost you money. 

They are going to use the profits of the sale to build an apartment over the existing attached two car garage OR build a tiny house on my property.
