Because of that, the deals I began targeting are tear-downs or houses that require a substantial amount of construction to fully maximize the size of the lot.

That is, investments that generated large passive losses that a taxpayer used to offset a significant portion of their income.  

Maybe I can keep that portion and remove the rest of it.

Lately, we have been trying to ramp up our flipping side of the business, we recently partnered with a local hard money guy here in Atlanta who has a pretty good deal for us (15% down, 85% on purchase, 100% on the rehab cost, doing up to 75% of ARV, wrapping our points into the loan, at about 9.25% interest- and we are coupling this with private equity investments from local guys to cover the 15% + carrying cost, in exchange for  35%-50% of the profits- depending upon the size of the job and capital required. 

The size of the home would only be around 1600 sq ft. and I am looking at going with a basic rectangular shape. 

Is anyone out there in a mid size to large market making profit soley from real estate wholesaling?

If you've never done a remodel before, I would suggest hiring a contractor and having a good sized cash amount in your contingency.

You could split it up and lease them out or one day you could even sell them individually. my guess is you could build another building that size on the lot too.

I will add to you small sample size Brian Larsen.
