I loved what you said about exchanging comfortability for profitability.

Here's mine:To Spend my time, knowledge, and energy on my passions in exchange for fulfillment, wealth, and purpose.

I found to her to have been helpful only when I had purchased new homes from her group, when I considered selling my homes or 1031 exchanges.  

Capital Gains are assessed on gains, so you'll not be taxed on the costs of improvements or costs of sale, as that would not be a gain.You may still be able to exchange this property, but you'll gain the needed clarity by speaking with an exchange company.

You may have to start small build equity and work your way up whether its 1031 exchange or just accumulating more assets..

@Turo Tales depends on your stratgey, however, to defer taxes, you could do a 1035 exchange and reinvest.

IDEAL situation would be to do short term (Airbnb) rental when it is not in use to supplement this luxury but I do realize with zoning laws/subletting and being a foreigner it may be problematic.I will be travelling to Ohau on March 27th - April 4th 2020.

It seems easier to use one person to handle all the exchanges but maybe that is not possible.Finally, whose responsibility is it to make sure all tax rules are followed?
