Cash-flow does not fit that equation.

If I were to put 2400 per year back towards the mortgage, the 6.375% equates to only (maybe) 150 per year that I am "making", but if you do that for a few years up front you can shave off years on the back end of the mortgage.  

You may have read how this is possible (it is "possible"), but the costs to do it will be very high given your lack of experience and know-how.You are looking for someone to invest with you, but what is in it for them in this equation? 

However, over the last 20 years there have been some favorable plms and rev rulings (particularly surrounding trusts) that owning a membership in an entity and converting that to tic still equated to the same level of ownership.

Pick 10 people that are in foreclosure, and ask them if they want to sell their house or keep it.Correct. 10 out of 10 will say: "keep it".Now pick 10 tax liens people from your amazing tax liens list.Same equation, Do you want to sell or keep?

That equates to $4,286 a year in tax savings.

Finding an investment isn't even half the equation.

The Taxable Value is uncapped and equated to the SEV upon a sale or other transfer of property ownership, with limited exceptions.Homestead versus Non-Homestead Millage RatesCounties & cities in Michigan are allowed to set their own millage rates, with one restriction – a primary residence (Homestead) is exempt from up to 18 mills of school taxes on their Homestead property.

As such hiring an attorney is out of the equation.
