You have the ability to sell while limiting your capital gains tax because you lived in 2 of the last 5 years. 

It is my understanding that the new owner will have the house at the cost basis of my purchase price, for calculating capital gains taxes or depreciation.For gift tax purposes for you - FMV.For capital gain tax purposes for the recipient - your original basis/purchase price 

Where is the income tax of 49% here?

Can you either rent out your current property if there’s been little/no appreciation, or sell it tax free?

The property owner's tax professional can help them with that and ensure they don't pay taxes twice on the same income.Disclaimer: My advice/opinion in this post is just that, my opinion.

This is tax free. 

This appears to be a 'transfer tax' instead of an income tax. 

Of course to maximize your tax benefit it needs to be sustainable over time. 

Is $107k your true net, or do you have any other expenses (mortgage, taxes, lodging taxes and fees, insurance, utilities, landscaping, WiFi, etc.)?

I'm looking for referrals for a custodian, tax attorney, and a CPA to set one up and advise me.
