So if I wanted a house for 517K, I would only need to put down $25K + Fees & Closing costs.My regular banks and credit unions don't offer this type of loan and I'm trying to avoid the PMI for a standard Jumbo loan. 

Obviously a licensed agent is the regular way to sell a home.

Not to mention, getting a HELOC can take a few weeks just like getting a regular mortgage as the underwriting is similar if not exactly the same.

If these are from a flipper I wouldn’t doubt they are overpriced...I get regular phone calls for management assistance from investors who were sold a bill-of-goods in Toledo only to realize they were had. 

If so, anything other than a regular purchase through the short sale process is a no-go, unless this Realtor is up for creative scenarios.

Invest in a low cost S&P 500 Index (if possible in your 401k) on a regular basis and since your 30, you have ~35 years until retirement, and whenever the market pulls back you can contribute more, because you know the market will go through several cycles before you need the money.Hope this helps @Emeric Harney 

I currently work a regular 9-5 that’s not so great in pay but enough to cover bills while I pursue my entrepreneurial dreams in real estate as well as another project.

They've just regular Joe's with no licenses or specialties.

I've told them that I'm an investor and I can't pay what a regular homeowner can pay or I wouldn't make any money. 

I believe you will have to pay taxes as regular income when distributing those proceeds to yourself.
