Through networking, I have come to the conclusion that to accelerate my investing I would like to find a commercial lender that is BRRRR friendly and can offer no or 1-month seasoning periods for refinancing cash-outs, so that I can keep my money free and maintain the ability to acquire more properties, when needed. 

In conclusion, it seems as though reducing your living expenses first, and then focusing on increasing your active and passive income will most likely accelerate your journey the quickest while you maintain your full time jobs. 

There has to be a way to accelerate things.Is leveraging my current rental the easiest option to get into a 2nd property in less than 5 years?

If you get a cost segregation study though that identifies a significant percentage of the property is actually personal property with a 5, 7, or 15 year life you would be able to depreciate it much faster- perhaps even in the year of purchase with the new accelerated depreciation rules. 

I make most of my income selling properties, and had just planned on using the Net Rental Income to accelerate the loan payoff. 

Other factors like adjustable rates, calls, etc can come into play to accelerate a loan below 6%.  

I have spent hours reading the posts and it seems like people either just do it in their own name, or suck up the fees associated with an LLC and take on a commercial loan.I also read you can quit claim on a deed but after reading a couple topics, it seems like there is still a 50% chance the lender will consider it as a full transfer and exercise the acceleration clause.

Even wanting to be debt-free, I'd have a hard time accelerating loans in the 3% range.  

Then 2018 with private lenders in place I will be largely focused on flips to accelerate the principle pay down on the portfolio before starting to add more or expand into commercial. 

If they wish to keep the house then they should be able to take over the loan and continue paying it since it would be exempt from a due on sale or acceleration.
