You'll pay ordinary income taxes on distributions only. 

Lets ask @Bill Exeter and @Steven Hamilton II for input, but I'll give mine.No, spec build are not elgible for 1031 because they're ordinary income, not investments.If you have an LLC you own sell you a house it will have zero effect on taxes.

None of the others had reviews at all, and very few of them looked like contractors that did ordinary work.  

Also, any interest and points income is taxed at ordinary income rates.

Currently, my exit is planned on all 80 rentals around 2021 from rental properties purchased between 2009 to 2016.I love paper way more but I think free and clear cash flow rentals structured properly for asset protection are a nice hedge against deflation/hyperinflation and also I use the depreciation as write-offs to offset my ordinary income as an agent/real estate professional.

I agree with @Brit Foshee that you should hang in their for the tax-free advantages, but would also advise that you include these issues in your consideration of your next project.

With flipping you'll have No capital gains tax....it's ordinary income plus self employment.
