This would allow you to maximize tax deductions at ordinary tax rates.

Also, if your AGI is below a certain threshold, you can offset 25k against ordinary income.

If I can park the 388k ($415-27k) for one year at CD rate of 4.5% and then est 300k (after paying cap gain/depr recap) at 3.0% (assume CD rates lower) that interest income of about 24 months net of ordinary income tax is about the same as my current mortgage.Trying to play devil's advocate and think why selling this year does not make sense. 

Quote from @Conrado Balicusto: Quote from @Chris Seveney: @Ryan DaultonWe use it for private lending - because the tax benefits are lost with real estate When lending usually it’s taxed at ordinary income rates if using your own cash so using a sdira I prefer for lending and my w2 income savings for real estate to maximize tax efficiency  Thank you for the insight on private lending and tax efficiency.

If you had identified the property, the cost and the travel cost would have been added to the basis of the property and depreciated.These initial investigatory costs are treated differently for flipping and rentals.1) Flipping: The travel cost to investigate will be treated as a business cost and deducted as an ordinary travel cost.

Plus it's ordinary income so it's a nice tax hit.

I could perhaps use Section 179 for the solar overall, as solar would be necessary, although not ordinary to conduct R & D. 

It can potentially be deductible as an ordinary or rental expense, an itemized deduction or simply non-deductible. 

It's pretty common practice to have something like that in a property management agreement, and if it falls under that limit they're going to pay it and not notify the owner except in regular monthly updates because it is below the threshold of what is an ordinary expense in the course of business.

Remember, if you decide to sell in a few years, any bonus depreciation comes back as ordinary income.
