The property value must be a minimum of $250,000 USD, and the credit score requirement is at least 700 points, among other conditions.

Learning from agents commonly working with investors is your next opportunity to find a mentor.To be honest, I wouldn't try to find a mentor from random investors on the internet.

However, aside from that, I couldn’t find much information about them, and the only online presence seems to be the wife’s LinkedIn profile (though I’ve never met her in person and am just going off her profile picture on Zillow).After submitting the application through Zillow, we attached our income (two months of pay stubs for each of us from our current jobs), work references, credit and criminal background, rental history, and the contact info for our current landlord (who just so happens to be my fiancé’s father).

I've been self-employed for only 6 months, and loans are proving difficult to come by despite my great credit (not to brag, I'm moreso frustrated and seeking help).

So, When one person, the GURU, has a lot of people sending him leads, most don't work out of course, but some do and they are blasted all over the internet.

Once you start processing the credit/criminal, the money is spent, and you can't get it back.

If I have several options, I would prefer a HELOC with no initial draw requirements (i.e. to establish a literal line of credit that I have no specific short term plans to use), i.e. not something like the better.com HELOC. 

No matter your level of experience, credit standing, or financial resources, Property Investment Funding, LLC is eager to partner with you.

Any local bank that does this kind of financing should be able to approve you as long as you have a good enough credit score and never declared BK.

Quote from @Jaycee Greene: Assuming you pay asking price, I'd estimate the down payment for something like that using a hard money loan (HML) would be around 40% of the purchase price and your monthly payment would be $2,600 with an interest rate in the low 7% range (probably need a 700+ credit score to get that).
