The single biggest advantage of selling your homestead is that you can take all the Cap gain tax free if you have lived in the home as your homestead for 2 of the last 5 years. 

It will familiarize you with the basic terminology and benefits.

The seller's LLC pays capital gains tax and depreciation recapture, while the buyer's LLC uses the purchase price as the new cost basis.

To Sum it up, its a good idea if you can exceed the cost of capital (higher rate than your cost of debt) with what you earn on your heloc/debt you pull out and invest.The question is how much gains above is enough to substantiate the risk of your variable interest rate, well thats up to your personal investing criteria.

Since the trust is a disregarded entity, the benefit is bypassing  probate, not tax issues or liability concerns. 

The reason being they see no benefit and they do not understand it.

I used to cold call, skip trace, send mailers, and don't get me wrong you will get success from it like James above, however as you gain experience you will realize you need deals faster, easier, cheaper, and with more "meat on the bones" and in order to have that you need constant deals flowing through your eco system and that's hard to do with mailers, cold calls, VA's and skip tracing etc.

They get a higher return since they are covering housing cost, have the $250k per spouse primary residence deduction in gains, is a savings account, higher leverage position, lower interest rate possible, will pay more premium for location, etc.House might be overpriced for REITs but not for home owners.  

I have been fortunate to meet two of those individuals and gained a mentor.
