I'm in the market for entity config and tax planning/prep.

$60k profit pre-tax.

To defer all tax you must purchase in total at least as much as your net sale.

Does Bigger Pockets have a clever scheduling function on it at all?! 

From a tax perspective, you'll want to take what you paid for the property plus calculate the improvements you made to the property during your time of ownership.

If 1031 is to be implemented it must be done on the property level.2. 1031 generally does not apply to IRAs since they are tax-exempt. 3.

There are also additional costs of operating and maintaining an LLC, like separate bank accounts, annual report filings, tax filings, etc.2.

There are two reasons this is a bad idea.Investing with an SDIRA (assuming it is not a Roth) will often result in paying significantly more taxes. 

So if you buy a 5 bedroom house and rent the spare 4 bedrooms = you can still sell tax-free under the 121 (you just pay back depreciation) If you buy a duplex and rent 1/2 and live in 1/2.

Be sure to hold a hefty reserve to handle on-going maintenance, capex, taxes, and insurance.
