Is this "fee" taxable ?

I was able to depreciate (off the top of my head) over 100k last year, meaning, my taxable income was 100k less even though I turned a profit on my rentals.

That is not possible within IRS rules, other than by taking a (potentially taxable) distribution from the IRA.The questions I would suggest you ask are related to keeping the Roth IRA as a tax-sheltered vehicle.  

This longer life would negate some of the tax benefits that are afforded to owners of residential rental properties (due to the shorter depreciable life on those types of properties), and would most likely cause your rental income to be taxable more often then not, right?

You need a legal professional who is tough when needed, wise and very experienced.Legal expenses are deductible against taxable income if you're structured properly.Then again, this is the type of expense you should only need to put out once.All that said, of course, it sounds like you need to be dealing with the local LLC-friendly banks.

Also, if your parents are listed as the owner, then they will owe any taxes on any taxable income from the rents, as well as being able to deduct the depreciation from that income. 

UBIT is Unrelated Business Taxable Income, as discussed above.  

Get the income first, then explore ways to reduce the taxable portion.My $0.02 ...

You could do a partial 1031 and take some cash out which would be taxable but still shelter the rest in the new rental.So many ways to go.
