Traditional mortgages are what you typically think of with a 30 year fixed rate loan or similar product.  

It would fall under a commercial lending product and most commercial lenders to not want homes in their portfolio.

I assume that whatever we offer will likely get declined, but just thought it'd be a good chance to try something that makes me hella-uncomfortable, and that is trying to buy someone's house who hasn't listed it for sale.Thanks in advance for any thoughts/experience, and hope I don't offend anyone.

Lenders will then easily be able to review your finances and provide you with estimated numbers on different products like FHA vs Conventional. 

The headlines and experts all seem to indicate the RE market will level off (maybe even decline) in the near future.

The only drawbacks right now is that lenders are not really being as aggressive on ARM products as they used to be. 

You can try and contact some local banks and see what loan products they offer.

My full time profession is marketing and media production (content creation, digital marketing, website design and optimization, sales funnels, etc.)My question is this:Since I have the professional chops to make a killer website, should I create my own site in lieu of the eXp provided site?

The difference between that rate and the IRR on the syndication is your net return.Doubling your investment is an aggressive assumption in the current environment with high borrowing costs and declining values.

Id suggest that since you changed loan products, presumably without the permission of the seller, that you pay to get these items repaired so that you close and do not default on the contract.
