You should be able to force appreciation by renovating and raising the rents over time to get the 25% equity, not only normal appreciation.  

I understand the equity chase and investing in several properties from the one.

So - if you can tough out this first one for two years and can force some additional equity over and above the price plus construction then you are ahead.

Hypothetically, if I had a deal that I wanted to put in front of a pool of investors, that underwrote to a mid teen CoC and above 20% IRR, however requires only a small equity slug - does anyone have any advice on finding an audience with those yield requirements?

So you don't make as much money as you would with a sandwich but there's less risk and you can sometimes do the deal even when there isn't enough equity or a low enough payment for a sandwich to work.

Rehabbed it myself made it look better added central A/c put in a lot of sweat equity. 

Maybe an older house on land you could buy that eventually might be torn down and a new larger one built.You could also buy in a new subdivision stage zero and when finished out in a few years hopefully have some nice equity growth.I tend to not like areas that are EN VOGUE currently because of a stronger economy.

Then just repeat this process until I have enough money to put down on a commercial real estate property to start acquiring equity. 

I am wondering what method can I use to pull this equity out of the home to purchase more homes through owner financing techniques. 

. - You get your cash back - you will have around 20% equity on each deal when you refiGiven that buying a distressed property and refinancing take you 6 months because of the seasoning period, It is still better than saving money each month to buy another property.
