Now, your question was more about lending and what's possible so to really explore that technique of purchasing will require more than just a simple answer like this but for the sake of time I'll leave it at that for now. 

With cash out refinance obtaining a HELOC at 75% LTV, this technique was so valuable because so little of capital is tied up.I love trustee sale because it's a very straight forward process most of the time.

Planners associated with infinite banking (which is a technique that can be employed early and help speed up your investing) and real estate investing experience are probably a better fit for what you're looking for too.

In many cases the free option might be the better decision when it comes to improving your cash flow because of how quick and easy it is and because it’s far less complicated than going through a refinance.Strangely, I’ve also noticed that most real estate investing books never mention this technique either, and in rare case when they do touch upon it, they almost always gloss over the benefits such as paying off your mortgage faster than you thought possible at no cost.

I'm now using creative financing techniques to build a self storage/industrial portfolio with 3 partners.

I know equity stripping techniques have already been discussed in a much more formal context. 

Someone suggested Doorknocking as a marketing technique for me. 

After foreclosures dried up, I have had to shift my business focus and marketing techniques until the next wave of foreclosures happens.

This is true some times, but in some scenarios, brand new properties end up producing significantly MORE maintenance/repair headaches than older properties.The reasons are:1) Some building techniques/materials are far superior to those used in the past, but some are not, and some are unproven.

I will be buying my first duplex in the next few months and doing the house hacking technique .
