@Derek Helm - I think our Ultimate Beginner's Guide and Podcast are probably great places to start to get you up to speed on real estate investing concepts and ideas.

We are curious as to how we can speed up the acquisition of new properties by utilizing an outside loan and this brings me to some questions.

The difficulty I'm reaching now is the good old DTI limit - my desire/ability to scale is outpacing the speed of my tax returns that verify my income/adjust my DTI.  

We understand the concept of buying speed and are willing to do so.

Still some of the challenges associated with "Class C" neighborhoods, but there is strong capital appreciation potential due to the anticipation of the high-speed rail line.

Out of money or out of deals is a common occurrence, but these are only temporary speed bumps. 

Now you're all driving the exact same speed at 60 mph.It is a mathematical reality that you are now all driving the same speed and you are not going any faster than anyone else. 

Usually speed wins, especially when we're looking at a market that has rising interest rates and more buyers that are waiting.As far as the advice about the types of houses to choose and sell, that will most definitely depend on your area and goals. 

Important to remember the baseline, though ... this is a from more-or-less stupidly high price appreciation and speed-to-sale times on the market. 

Even if the seller is not concerned about speed, the "sure-thing" cash offer will almost always trump a financed offer.
