Simply gifting him half the property now wouldn’t immediately allow him to claim the exclusion without fulfilling this residency requirement, I don't believe.One thought would be to use a HELOC to pull just enough equity out of the current home and use it to buy a smaller home, or at least the down payment.

What I don’t understand, and help me on this, is why someone would simply want to purchase the Mortgage/DOT without the note. 

You never get hurt taking a profit.  

., to be honest, if you can't simply explain it in a post, you have already lost a vast majority of investors.  

Im assuming that is what would catch any errors in owner distributions, deposits, profit/loss? 

In order to do this you need to have deal flow and you need to know 1) How to recognize a good, profitable deal, 2) How to put together funds quickly to buy the deal before someone else does and in such a way where you are protected and the deal is protected, 3) How to run the project so that you follow the budget and don't overspend or overbuild, 4) How to attract an end buyer or a renter and which documents to use to protect yourself and the buyer, 5) If you are going to keep the property then you need to know how to set up the property from the start to best help you in the refinance later, and 6) You need to know how you are planning on managing the property from the beginning in order to make sure it will be profitable at the end.

Without a firm base and working familiarity with these three areas the investor will not have the knowledge to analyze, negotiate and close advantageous real estate transactions. 2- Experience - the first few deals are likely to be smaller, harder, with more “surprises” and not as profitable as the investor imagined.

I find that hard to believe, but you can always call HR and simply say you are trying to confirm if X works there and not say why you need to know.

Considering that, you are likely going to see appreciation year over year, which essentially will be additional equity you'd capture just by simply living in the home. 

Oversimplifying it just a bit, the investor profits from:- a non-refundable option paid by the tenant-buyer which gives them the right to purchase the property within their option period- the spread between the rent paid by the investor to the property owner and the rent paid to the investor by the tenant-buyer over the life of the option- the spread between the price ultimately paid by the investor when they exercise their option with the owner and the price ultimately paid by the tenant-buyer when they exercise their option with the investorClear as mud?
