could you expand on your techniques for finding buyers, or explain a little about your network, i.e. selling to other investors...

Using available data and financial techniques I developed over time I identified a few neighborhoods that have homes that if bought and rented could provide the mix or rental income and gross yield that I seek. 

Keep in mind when using a "no money down" technique, you are still paying, just in other ways like with your time, effort, blood, sweat, first born...I know a bunch of guys that are doing a lot of deals, and most of them are not really killing it.  

The IRS doesn't have any set qualifications or licenses required to do cost seg, but they assume cost seg is only done by individuals with knowledge of construction, construction techniques, design, estimation procedures and the tax code i.e. construction engineers or architects trained in cost seg.

Now that the market is slowing down, I'll probably start using this technique again.

What are the benefits of that technique?

@Bill Hampton nailed itI'm for posting the resources such as books, read first then speak to a profissional CPA so you can understand what's being conveyed.Bigger Pockets has published a The Book on Tax Strategies for the Savvy Real Estate Investor: Powerful techniques anyone can use to deduct more, invest smarter, and pay far less to the IRS. 

I'm currently utilizing the same marketing technique (post cards to absentee owners via Click2Mail), and I'm still getting calls and potential leads.

It is such a localized industry I don't see how they can teach applicable techniques.

These were based on very specific conditions that must be met without exception.We have even used these techniques for pre-nuptial agreements and post nuptial agreements and for partnership in businesses by using a UCC1 filing instead of a mortgage lien or a Trust DeedA final point: this structure is powerful but is no substitute for acting prudently, having the proper insurance coverage and never thinking that insurance is a waste if money because you have not been sued.Choose an experienced attorney who is not trying to gouge you because all your assets could be stripped with just one entity.Many times investors go to Attorneys asking for asset protection and the attorneys steer them away from equity stripping because it is a lot of tedious and specialized work, so most are unfamiliar with it and frankly it does not pay much.Most attorneys would rather structure several LLCs for each of your assets and flow them through to Corporations that are anonymous in NV with them (the attorneys) as nominees using Land Trusts with them yet again as Trustees and so on..
