@Parius Futch Since TK is just a shortcut way to purchase properties with renovations completed and tenant in place (don't buy TK unless this is part of the deal), and given that you already own properties so have experience under your belt, it is definitely a faster way to expand vs doing it yourself. 

No need to wow the tenant unless it's getting it rented that much faster or for a higher rent rate.

The faster you get in deep, the more you will learn.Good luck.

And you have better chances getting REO because you can see the property faster and make the offer as property come on the market.

Once you figure this out then you need to find a mentor to help you get there faster.

@Eric Teran how much cheaper/faster is the modular/prefab route vs traditional construction? 

Which once able to take out equity from the second purchase and the repayment of the first home equity lone of credit, after having the necessary 20% equity in a mortgage if not needing the money for a current purchase, utilize home equity lines of credit on each mortgage, and use the money from the HELOC and pay down the same mortgage to be paying down the principal substantially faster on each property free and clear. 

I know it is unpleasant, but the faster you deny the better.

In class will be faster

In terms of geography, I would think large, affordable and sunny locations are growing faster than small, expensive or cold locations.
