From a strictly cash flow perspective, not ROI, Cash on cash, etc where you would benefit from the leverage, paying an expense such as mortgage interest only puts a portion of that back in your pocket on taxes. 

Fairly new to this and although I understand how to run most of the critical calculations to analyze the deal the part I am struggling with is understanding the best methodology when it comes to the "Refinance" portion of the deal.There are (2) extremes:Option 1: Take the full LTV that is offered even if it means running cash neutral/negative as it is buying the next house and the combined income of the (2) houses versus one is more than just the one.

What are some options for their ability to request repayment of their contribution plus their portion of the appreciation?

There has to be logic to that somewhere, and it sounds like nobody really understands it all, but some people understand specific portions of it.

You can withdraw some portion (or with pre-tax dollars of a 403(b) all) of the funds but you WOULD likely incur a penalty and/or a tax.The "hack" of using your retirement account funds in investment real estate comes primarily from the idea that you can funnel funds into a Self-Directed IRA from a number of different sources (like rolling over a 403(b) when you separate from the service that sponsored it).
