I would like to manage a real estate fund as my day job in the future. lets just say hypothetically I am making $2 million a year from this and that is ordinary income.

Either an assignment or a "flip" would both ordinary income, including self employment taxes.

One BR units are significantly less valued by investors than 2 BR.  It

Invest after that and it's with post-tax money and you'll pay ordinary income taxes in dividends.

Knowing distributions from an IRA are going to be reported as ordinary income, and typically many years in the future, is the value of depreciation deduction lost (or partially so), when buying units inside a self-directed IRA?

Quick one,I understand profits from wholesaling activities are tax as ordinary income; but, is there a way to minimized the taxes that one needs to pay from money earned in wholesaling?

@Curt McClements if you are looking to invest in anything over a SFR as an investor ordinary financial institutions want the investor to put 25% down on the property.

If it takes you 4 months from start to finish buying,rehabbing,and then closing to make the profit at a 15k margin you would gross 3,750 a month for the time invested.You also get taxed at a much higher margin than ordinary income correct??

It will be taxed as ordinary income with self employment to boot.
