I was thinking something like a Trader Joe's (small footprint grocery that people will travel to shop at) and maybe another coffee shop or restaurant.

DO NOT TRADE RENT FOR WORK.

In fact day traders flip the same stock many times tax free in IRAs.

Exploiting private partnerships would necessitate that the trader understand tens of different asset classes better than the MPs that allow for the security to be traded at a discount.

If you are interested in more of the transactional type deal and market at hand (day trader), appreciation may not be a factor. 

Another example is how many BP'ers are among the top 200 note traders in the country?

You may also want a TIN for your Ira If you are doing wholesaling that would be considered a “trader business” and UBIT would apply.

I'm kind like making a comparison between the tax treatment of Real Estate Pro Status and Trader Status Pro:Stock/Futures Trader:- trader trading futures has a preferable tax rate instantly although one doesn't have trader status- For trader status, they could write down the unlimited number of losses instantly, it's not hard to attain trader status once the LLC is in place, one just need to display their trading logs.

While stock investments are also generally passive, you do have those that consider themselves active traders.

.- Better- Gambler- Speculator- Trader- InvestorThe gist that I got was the difference between investors and speculators are hold period and leverage.
