I am open to the a person having a business model that is successful without banks.

This is the first time I am trying this so I hope they come through.Also, I am actually hopeful that the costs will end up closer to 3500 since they said the closing company is trying to get me some discounts since I am closing multiple cash out loans simultaneously.Now after this the issue is finding more properties that I can use the same model with :-), they are getting to be few and far between.

Depends on your business model but for buy and hold ... would go with 30 years because I could get more properties leveraged.

ALL of these systems use the exact same model (free seminar, three-day training up sell, additional training up sell, mentoring up sell).

Tour/show a model to the public.5.

My goal is to develop a model that can be repeated from one property to the next. 

Essentially this model puts an LLC between your SD IRA and the investments, the major benefit of this is what you see advertised as "Checkbook Control" which is a simple way of saying you control the LLC which invests in assets, so you have a checkbook possibly debit card, and whatever other products your bank account comes with.

Many of us including myself talk about our strategies, styles, niches and business model on our website.

Account Closed you can reach it with any real estate investing strategy - the best approach is to do whatever you really enjoy doing and then model after those who reached the goal. 

It can also be used as a point of negotiation with a serious buyer, plusthey can pick the model they want.
