Really no feasible reason for a licensed individual to get into the NET listing or assignment nonsense.

But I can tell you my plan that seems to be feasible. 

But if you put the effort (and money) into targeting 5000 or 10,000 properties you will have a much better shot than if you're targeting 350.Only you can realistically evaluate if that is a feasible course.

If this is feasible I could then pay off $60k to my Uncle ($20 for the downpayment and $40 for renos + a profit) and use the rest to build an emergency fund, and work on my next deal...

No reason not to have others helping pay the mortgage & build equity.I know you can make that happen with conventional investment financing (25% down), but I have to defer to @Jerry Padilla on the differences/feasibility of financing it as a personal vacation property. 

Is it feasible to use a hard money lender as a new home builder?

Does anyone have any thoughts on the feasibility of something like this?

Experienced investors who are known quantities AND pleasant and trustworthy people to do business with will get "expensive" but very feasible prices for money.If you want 6% - 8% for five years better talk to your Aunt Sally.

With that said, is it even feasible to use a HELOC instead of a refi?

He says he did not detach the receipt prior to mailing...he has done this in the past, so it's entirely feasible he did this again.
